Short range data transmission. With it, you can exchange data between devices located at a distance of about 10 cm. NFC is a radio frequency data exchange at a frequency of 13.56 MHz, so it does not require the Internet to use it. Unlike Bluetooth, NFC does not require manual pairing or device discovery to transfer data. The connection starts automatically when another NFC device enters the range specified above.

make contactless payments with NFC NFC supports three modes of use:


1.- Read/write.

2.- Point to point.

3.- Card emulation.

At first, the devices would be used as smart cards, for example, when making a payment. In the second mode (Peer-to-peer), two NFC-enabled devices communicate with each other to exchange information and files. For example, in peer-to-peer mode, users can share Bluetooth connection settings, Wi-Fi, or photos. In the third mode, devices read information on NFC tags or tags embedded in billboards and smart displays, or write information to them. This mode allows you to read transport schedules, tourist labels and routes.

NFC devices consist of a reader and an antenna, or a tag and an antenna. The reader generates a radiofrequency field that can interact with the tag or with another reader, it operates in active communication mode. This type of communication is used in peer-to-peer mode. The tag is an NFC device that uses it in passive communication mode. This means that the tagged device uses the field generated by the initiating device. This type of communication is used in all NFC modes.


What is NFC technology on my cell phone and what is it for? NFC technology specifications

In addition to existing standards, the NFC Forum has compiled the best of these standards into documents that describe the use of devices using NFC technology and call them specifications.

For example, the enhanced NFC technique addresses the RF performance of an NFC-enabled device. This selection includes antenna power requirements, transmission requirements, receiver requirements, and waveforms (time/frequency/modulation characteristics).

NFC Analog 2.0 selection introduced active communication mode for P2P communication and NFC-V technology in polling mode.Version 2.0 provides full compatibility with devices that comply with ISO/IEC 14443 or ISO/IEC 18092.

Based on these specifications, the following communication methods exist for devices with NFC tags. NFC devices can be active or passive communication and exhibit one (or more) of the 3 modes of use.

1.- NFC-A communication method.- The NFC-A communication type is based on the ISO/IEC standard 14443A for contactless cards. Communication types differ in the signal coding and modulation modes used. NFC-A uses Miller code and amplitude modulation. Binary data is transmitted at about 106 kbps, the signal must change from 0% to 100% to distinguish between binary 1 and binary 0.

2.- NFC-B communication method.- The NFC-B communication type is based on the ISO/IEC standard 14443B for contactless cards. NFC-B uses the Manchester encryption method. Binary data is also transmitted at about 106 kbps. Here, instead of 100%, an amplitude change of 10% for binary 0 (ie low) and 100% for binary 1 (ie high) is used. In Manchester encoding, a transition from low to high represents a binary 0 and a transition from high to low represents a binary 1.

3.- NFC-F communication method.-
The NFC-F communication type is based on the FeliCA JIS X6319-4 standard, also known simply as FeliCa . The standard is governed by the Japanese JICSAP. This technology is the most popular there. Data transfer rate 212 / 424 Kbps, using Manchester coding and amplitude modulation.

What is and what is the NFC technology of my cell phone for?  
1.- Card emulation mode.- The card emulation mode allows NFC-enabled devices to act as smart cards. In card emulation mode, an NFC-enabled device communicates with an external reader like a normal contactless smart card. For example, when making a payment with an NFC-enabled device.

2.- P2P (peer-to-peer) mode.- The point-to-point mode allows two NFC-enabled devices to communicate with each other. communicate with each other to share information and files, so users of NFC-enabled devices can quickly share contact information and other files with a single touch. For example, users can exchange Bluetooth or Wi-Fi connection settings, or exchange data such as virtual business cards or photos.

3.- Read/write mode .- The read/write mode allows NFC-enabled devices to read the information stored on NFC tags (or tags) embedded in billboards and smart displays or communicate with another NFC device in read/write mode. The initiating device can read data from or write data to the second device. Using labels, you can read transportation schedules, access special promotional offers, read travel labels and routes, and more.

What is NFC technology on my cell phone and what is it for? NFC active and passive communication

1.- Passive communication.- In the passive communication mode, there is an initiating device, there is a target device. The initiator produces an electromagnetic field at a carrier frequency of 13.56 MHz, which enables data exchange and sends power to the target. The initiator then sends a command using direct field modulation. The listening device (passive or polling) responds using load modulation. This type of communication is used in all three NFC modes. In passive communication mode, the target device uses the field generated by the initiating device.

2.- Active communication .- In active communication mode, each device generates its own electromagnetic field. The initiating device generates an electromagnetic field at a carrier frequency of 13.56 MHz, uses amplitude modulation to send a command, and then deactivates the field. In response, the target device generates its own electromagnetic field and, modulating it in the same way, sends back a response. To avoid collisions, only the device emits an electromagnetic field. This type of communication is used only in P2P mode.What is NFC technology and how to activate it

Highlight the convenience of using NFC in Bluetooth and Wi-Fi networks as a mechanism for pairing and integrating a device into a network. This applies not only to smart homes. You can connect your mobile phone to a public Wi-Fi network. Connect a Bluetooth accessory to a mobile phone via NFC, such as a fitness tracker, headphones, speakerphone, Bluetooth wireless connection, billions of smart electronic objects. While Bluetooth technology provides the convenience of being always connected from a distance, pairing two devices via Bluetooth can be frustrating for the user (it is for me) when they have to search for these devices, then pair them and enter more code from the box. . Through close collaboration between the NFC Forum and the Bluetooth SIG, NFC helps speed up Bluetooth pairing by eliminating the long pairing step. Manufacturers of Bluetooth-enabled products can now encode pairing setup information on a thin, flexible NFC tag embedded in a Bluetooth-enabled device and provide an instant, secure, one-touch connection with another NFC device.

The same goes for connecting devices to a Wi-Fi network, thanks to the NFC Forum and the Wi-Fi Alliance. Using NFC tags makes it easy to connect to a wireless network at home, in the office, and on the go. Merchants and cafes protect their Wi-Fi networks with a password. To connect to a Wi-Fi network from a smartphone, tablet, or PC, the user must open the Wi-Fi settings, select the correct network name (SSID), and then enter the password. In April 2014, the Wi-Fi Alliance and the NFC Forum announced technology enhancements that can eliminate two key problems when connecting to a wireless network: choosing a network name and entering a password. To achieve this simplified connectivity, NFC Forum standard transfer information is encoded on a thin, flexible NFC tag that is integrated into the wireless router, either mounted on the wall, or even distributed as a business card. As soon as the user connects their NFC device to the NFC tag, all the necessary configuration information is automatically transferred from the NFC tag to the mobile device. With a simple tap on an NFC tag, users can surf the Internet faster than ever before.

The technology is used not only for contactless payments and tag reading. NFC is also used in smart home devices, cars, and even as keys.

What is NFC technology on my cell phone and what is it for? To make payments with the mobile phone

NFC chips are used in plastic cards for contactless payments, as well as in chip-embedded rings or bracelets. Usually, the bank's payment application is embedded in the chip, which interacts with the seller through the payment system during the transaction, as well as the customer's personal payment data. They are stored encrypted. The card's NFC module provides a contactless connection with the reader.

By emulating a card in a smartphone, the data is stored in the TSM (Trusted Services Manager), which integrates service providers and Secure Element chips. It is a complex of hardware and software that provides secure boot and security management using over-the-air (OTA) cellular technologies. TSM allows you to install and configure applications in the security element of the mobile phone and then maintain them.

What is and what is the NFC technology of my cell phone for? To identify yourself with the mobile

NFC technology is used for access control or identity verification. The technology allows, in addition to the usual access control, also to pay for services and accommodation, create passes, verify identity or grant other permissions. The simplest example of the use of NFC is in intercoms, where a tag with a key is sewn on the keyring and a tag reader is installed on the device at the door.

Hotels also use NFC to control customer flows and access based on privileges. Guests of such places do not need a physical key, as they can enter the room or visit other areas with just a smart. Your credentials are generated in real time and all transactions are processed directly on your smartphone to prevent data leaks or theft.

What is NFC technology on my cell phone and what is it for? For mobile trading

Companies offer users to store their bonus and gift cards, as well as loyalty cards in "e-wallet" applications, so they don't carry them around. With Google Pay, loyalty cards are integrated directly into the payment app, allowing you to pay for contactless purchases using NFC. Some stores also allow you to link coupons within their own apps. At the same time, the card data is stored in a secure element (Security Element or SE) of the smartphone, which protects it from being erased.

What is NFC technology on my cell phone and what is it for? For transportation with the mobile phone

NFC-based contactless transport cards are used in transportation, as well as in ski resorts on lift systems and funiculars. You can usually top up the card at a transportation ticket kiosk or online. It can also be integrated with Apple Pay and Google Pay. In August 2021, Moscow began testing Troika virtual card payments in Samsung Pay.

What is and what is the NFC technology of my cell phone for? For the protection of the car with the mobile

What is NFC technology on my cell phone and what is it for?  
An application on an NFC-enabled device allows you to use your smartphone as a car key. Simply hold it close to the driver's door handle to lock and unlock the car doors. In the cabin, the smartphone is placed in a special place on the dashboard, which is also a wireless charging pad, which allows you to start the engine.

In 2020, the Car Connectivity Consortium, which brings together car and mobile device manufacturers, released the preferred Digital Key Release 2.0. Includes support for vehicle locking and unlocking, engine start, user authentication, revocation of another user's digital key, digital key exchange, and key restriction. The latter is stored on the SE of the smartphone. Installed in-car NFC sensors are on the driver's door handle and on the front panel.

Apple introduced its NFC car key. Car Key can be linked to the Wallet app, allows you to unlock and start your car using your iPhone or Apple Watch, and can also be shared with others.

The introduction of NFC technology, in the car infrastructure will affect the cost of the model in the direction of increase. And more security. Although the manufacturers of NFC devices claim that it is one of the most secure technologies, due to its very limited range, it is almost impossible to scan it remotely, the reader must be at a maximum distance of 10 centimeters and the digital key is stored in a secure element of the mobile device.The limited range, by the way, on the other hand, can also be a certain problem, because the phone will have to be brought directly to the car door handle, you will no longer be able to open the car while standing in the store with full packages in their hands, as if with a key chain button.

What is and what is the NFC technology of my cell phone for? Identification and Access Control

NFC technology has a wide application in the hotel industry. This of course is not just about hotels, if we take a broader meaning then NFC technology is used for access control or identity verification. NFC provides access control to certain rooms or groups of rooms, first of all the room, this is a hotel room, but depending on the client's privileges, they can access the SPA area, or any other area or room where access is limited . NFC can also help hoteliers or owners monitor performance by keeping track of people visiting a particular room or passing through an area.

The hospitality solution offers guests a completely new experience. Depending on the chosen solution, guests can pre-book and book rooms themselves using their mobile devices. Upon arrival, they can use their smartphone to check in or out.

When guests arrive at the hotel, they immediately go to their room and open the door with their smartphone. No more queues at the reception after a long journey. No keys or cards. This solution is safe, convenient and saves time for everyone.

Both guests and hospitality companies benefit from the use of NFC in a hotel. For example, a guest can enter their room faster if their smartphone is programmed to open the room lock, with NFC technology, and also eliminates the need to carry a physical token (eg an o card). In this case, it is unlikely that you will forget the key inside the room; According to unofficial statistics, one in two people does not part with a smartphone. And hotels save on the cost of physical keys.

In the event that NFC is used to control access, such as an event, exhibition or entertainment complex, owners can save costs by digitally registering attendees instead of issuing physical cards, badges or tickets.

What is and what is the NFC technology of my cell phone for? For medicine with the mobile

NFC can provide secure access to medical information. The technology is used to control access to computers, tablets and other devices.

NFC-enabled medical wristbands allow you to track patient movements. The staff can know in real time where the patient is, when was the last time the nurse visited him or what treatment his doctor received. The bracelets can be connected to smartphones or tablets so that they transmit data to the treating doctor. NFC smart bracelets also help track patients with life-threatening conditions like diabetes, asthma or allergies. In an emergency, the bracelet will provide detailed information to emergency physicians. HealthID Profile launches similar devices.

Finally, NFC tags are added to a drug's package or label to verify its authenticity, view detailed dosage information, or read about side effects. The label may also contain a web link to the manufacturer's website.

What is and what is the NFC technology of my cell phone for?  
In the gaming industry, the technology is used in the form of tags in which data is recorded, which is imported into the game application in the form of a hero or playing field. Activision released the game Skylanders: Spyros Adventure, where the characters were associated with real physical figures that are equipped with an NFC tag. The figure must be purchased and placed in a special portal so that the hero appeared in the game. Nintendo also implemented this strategy in the Amiibo game.

Activision has two game series that consistently feed them year after year. It is, of course, a series of Call of Duty games that breaks all possible records, as well as a series of children's products called Skylanders. Born as an offshoot of the Spyro the Dragon series, Skylanders has grown into a standalone series that has been released on multiple platforms. The series is so successful that, watching it, Disney spent a lot of money to make their Disney Infinity game with a similar message. And the point is that the heroes of the game are associated with real physical figures of these heroes. The figure is equipped with an NFC tag, this figure must be purchased and placed in a special portal so that the hero appeared in the game. This is genius. Skylanders revenue doesn't come from sales of the game itself, but from all these hero figures for it. This idea was followed by Disney Infinity and Nintendo Amiibo for Nintendo consoles. Implementation From the above, it is clear that in the gaming industry, NFC technology is used in the form of tags on which data is recorded, which is imported into the game application in the form of a hero or playing field. A little NFC magic from NXP:

What is the NFC technology of my cell phone and what is it for? For Internet systems (IoT) with the mobile

IoT systems use devices and sensors with different interfaces and connection mechanisms. Integrating an NFC interface into an IoT gateway or a microcomputer that acts as an aggregator for all devices allows you to seamlessly connect them. At the same time, an NFC-enabled smartphone, after registering with the gateway, can be used to send commands to devices and change their settings. In addition, the technology allows you to control even devices without an interface: light bulbs, security sensors or plugs.

NFC can also act as tags. They run without power and are small enough to fit inside a poster, ticket, business card, sticker, bracelet, key chain, pen, tag, and more.

The microchip in the tag can store small bits of data that can be read by an NFC-enabled device. An NFC tag can store a URL, contact information, or even commands and settings that the device will perform on the contact. To read or write data to NFC tags, use a special application, such as Trigger.

The integration of the NFC interface in the smart phone IoT gateway) allows you to seamlessly connect all devices to the gateway, regardless of the underlying technology wireless connection. An NFC-enabled smartphone registered with the gateway can be used as a "magic wand" to transfer settings to devices, a device can also be restored to factory settings or disconnected by touching a mobile phone's settings. a device can be copied to another, making it easy to replace the old device with a new one. NFC provides standardized mechanisms to support all of these deployment scenarios. What is NFC technology and how to activate it

NFC World maintains a list of smartphones with technology support. According to him, every iPhone since iPhone 6 found it. The latest iPhone 12 also supports NFC tags via the Launch Center Pro app.

NFC has also been added to the iPad lineup, starting with the iPad Pro, iPad Air 2, and third-generation iPad Mini.
All devices running Android 4.0 or later are available with NFC support. Samsung, for example, separately publishes a list of its NFC-enabled smartphone and technology specifications.

The NFC function is also built into smart wristbands, for example the Xiaomi Mi Band series. A smart watch with NFC can be used like a smartphone with the same chip. Generally, its use is limited and is used only for purchases and services.

There are NFC rings to pay for purchases. The rings can be used to pay for public transport, as well as an ID card. To use the ring, you need to install an app from its developer on your smartphone.

What is NFC technology on my cell phone and what is it for? How do you know if your phone has NFC?

In the case of Android smartphones, you need to go to the settings and enter "NFC" in the line "Search", and then connect the option. In quick settings, the N-shaped icon is usually found next to the Wi-Fi and Bluetooth icons. Also, some companies place NFC symbols on the battery of the smartphone. Finally, you can install one of the free NFC-enabled apps from the app store Scan the device and if the chip is embedded in the smartphone, the message “NFC is: supported appears on the screen ". If the chip is not provided, the program displays the message "NFC: not supported".

On iOS devices, you don't need to set anything, just take the phone to another device. However, you will need to set up billing for various services with your Apple ID where you are signed in to iCloud. iPhone 6 and 7 models made NFC payments with up to eight bank cards, and newer models can make payments with up to 12 accounts activated on one device.

What is and what is the NFC technology of my cell phone for? How to check if a phone has NFC?

There are several ways to find out if a particular phone supports this option. When you decide to buy a phone with the NFC function, it will be easier just to study the "Specifications" sections in the description of a particular device on the store's website or look for reviews of the selected smartphone on the network. If you have already purchased the device, you can find out if the device supports NFC in the following ways:

Read the labels on the box. There the presence of this option will be indicated or a corporate icon will be displayed.

1.- If the phone has a removable back cover, you can remove it and inspect the battery, which should also have a battery label. caveat. You can also see the antenna, which is a flat coil. It can be fixed on the back cover.

2.- Go to the configuration and go to the "Wireless networks" menu item. If you click the "More" button in the presence of a built-in module, the user will have access to actions that can be assigned to NFC.

The most popular NFC feature is still contactless payment. On Android smartphones, you can use Google Pay or Samsung Pay to pay for goods and services.

What is NFC technology on my cell phone and what is it for? With Google Pay.- Google Pay, formerly known like Android Pay, it allows you to make purchases and transfer money. You can also use loyalty cards, gift cards, and travel cards in the app. You will need a Google account to use.

You must first set up Google Pay. After downloading it from Google Play, you need to select your country of residence, Google account and enter your phone number. Then you need to enter the code from the message for authentication. Adding a debit or credit card is done in the Insights tab in the bottom right corner of the screen.

To add a loyalty card, gift card or transit card, you need to click on the credit card icon in the upper right corner of the main screen of the application.

You can link a bank account to Google Pay to top up your balance. To do this, go to the Statistics tab, select "Google Pay balance" and "add money", then enter the desired amount and click on "add bank account ".

To pay for purchases, you need to make sure NFC is turned on, and then hold the back of the device close to the payment terminal for a few seconds. When the payment is complete, a blue checkmark will appear on the screen.

What is NFC technology on my cell phone and what is it for? How to pay with Samsung .- Samsung Pay, a Unlike Apple Pay and Google Pay, in addition to NFC technology, it uses the MST or Secure Magnetic Transfer function and use it almost everywhere, even in older terminals that have not been updated to work with contactless payments. However, in 2021, support for this feature began to phase out, starting with the Galaxy S21 phones. Samsung Pay is available in 29 countries, including Russia. It is also available in the Galaxy Watch, Galaxy Watch Active, Gear and Gear Sport lines of smartwatches.

To set up the service, you need to launch the app, sign in to your Samsung account, and register a PIN or scan your fingerprint. You can add credit and debit cards from Mastercard, Visa and MIR payment systems to Samsung Pay, as well as make money transfers. In addition, up to 100 loyalty cards can be loaded into the service.

When paying, you must select a card on the main screen of the application and then place your finger on the fingerprint scanner or enter a PIN code. After that, you can connect the back of the phone to the payment terminal. A pop-up notification of transactions will appear at the top of the screen.

What is and what is the NFC technology of my cell phone for?  
The NFC function on the iPhone, as already excluded, is activated and deactivated by those applications that require it. To link a card to Apple Pay, you need to go to the Wallet app, click the "+" and follow the instructions. Since 2021, Russian users can link, in addition to Visa and Mastercard.

To pay, you need to place your finger on Touch ID or swipe on Face ID and hold the top of your iPhone close to the contactless reader. The smartphone itself activates NFC.

While the original NFC-enabled iPhone 6s only allowed payments through Apple Pay, iPhone 7 and newer models use technology to read NFC tags using third-party apps. Additionally, starting with iOS 13 and the release of the iPhone XS and XR, they can also encode blank tags using third-party apps like GoToTags. And finally, from the iPhone XS to the iPhone 12, smartphones are capable of reading labels in the background. Therefore, the user no longer needs to install third-party applications: simply touch the NFC tag to the iPhone and it will automatically read it. The system automatically searches for nearby bookmarks each time the screen is turned on. Once the tag is found and compared, it displays a notification that the user can submit data to the application for processing. However, background reading is disabled when using Wallet or Apple Pay, cameras, device is in airplane mode, or locks after restart.

To enable other NFC features on your iPhone, you need to launch the Commands app, open the Automations tab, tap the + in the top right corner, search for NFC, and select NFC Tag. Then you need to turn on the Bluetooth headset or other wireless device, connect it to the iPhone, bring the labeled device to the back of the smartphone and wait a couple of seconds. After connecting, you need to open the "Scripts" menu, select "Set Playback Location" and specify your iPhone; then select the connected device from the list and uncheck the "Ask when performing" box. The procedure must be repeated for each device.

NFC technology What is it and how to configure it? Security in NFC technology?

What is and what is the NFC technology of my cell phone for?  
In the early 2000s, NFC modules were designed invulnerable to hackers. However, the programmers later described a series of theoretical attacks that they could use to steal information and infect a smartphone with a virus. In 2012, the first critical NFC vulnerability was identified. At that point, MWR Labs finished the process of transmitting a virus, infecting a device, and taking full control of a smartphone in just five minutes. To do this, it was enough to bring the device to a label that contained malicious code.

To date, NFC signals are encrypted using cryptographic algorithms, and new encryption protocols are being developed in parallel. Also, in mobile banking apps, payments often require additional confirmation with a PIN code, fingerprint, or iris photo.

make contactless payments with NFC Secure NFC data storage Using a protected element, Of course, this has already been mentioned in the previous sections. One option for storing card credentials and sensitive information on a smartphone is the security element. We remind that SE is a physical chip on which applets of some applications with sensitive data are installed, for example, an applet for a payment application, a transport application, etc. This chip can be part of the mobile device's hardware platform, a SIM card, or even an SD card. We also record that the SE applets and data are managed by TSM, a trusted service manager. Rice. 21. Applets in a protected element.

All sensitive data, such as data associated with a virtual card, that is stored on the SE is protected in the same way as on a physical contactless card. However, there is an important difference. The SE is permanently connected to the smartphone and via the smartphone to the Internet. The potential of attacks is much higher than that of a real card. Data on a normal card can only be accessed if it is near a proximity reader and only if the proximity reader has been tampered with. This implies the need to control access to applets on the SE. And now, another nonprofit organization that develops specifications for secure digital ecosystems in the United States, the Global Platform, has lost the Trusted Execution Environment Specification, or TEE.

This environment, such a layer between the OS of the mobile device and the SE, in which the exchange of data and commands is protected. Here are the Global Platform specifications on cryptographic algorithms, TEE system architecture, etc.

make contactless payments with NFC Experts recommend following the rules:

1.- Make contactless payments ONLY in verified places: gas stations, supermarkets, coffee shops and shopping malls.

2.- Do not bring your smartphone near NFC tags located in public places, including advertisements.

3.- When using an NFC-enabled self-service terminal, check for stickers or other foreign objects.

4.- Do not share your smartphone with other people or place it near other devices in public places.

5.- Scan your smartphone for viruses and update paid applications.

6.- Deactivate the NFC function when you don't need it.

What is NFC technology on my cell phone and what is it for? How do they steal bank cards?

Skimming (from the English "to skim" - read fluently, swipe) is a type of bank card fraud, which is the reading of information from your magnetic stripe using a special technical device or a skimmer. Fraudsters also try to find out the victim's PIN code. After receiving the card details, you can copy them and withdraw all the money. RBC Trends found out how to use this technology and what steps you should take to protect yourself from this type of fraud.

To read data, skimmers are used - special devices that connect directly to the ATM, as well as to any receiving slot of the card capture reader. Fraudsters can set up portable magnetic stripe readers in hotels, cafes, restaurants, and stores.

A skimming device typically includes a magnetic reader, a converter that converts the information into a digital code, and a unit that writes the digital code to a data carrier.

make contactless payments with NFC Skimmers are of two types. Some accumulate information about different users, while others immediately transmit card data to fraudsters via a radio channel or via an embedded SIM card over cellular networks.

1.- Physical skimming is used in ATMs and terminals payment. Payment skimming is made possible when the vendor, waiter or any other person asks the buyer or customer for a card. At that point, you pass it through the reader, which is located next to the payment terminal and out of sight.

2.- Online skimming use it with malicious software. ATMs in card transactions can perform magnetic stripe data transfer in clear text. If the network connection between the ATM and processing is not protected by encryption, fraudsters can "eavesdrop" on the traffic through special overlays. They can also use social engineering to infiltrate the computers of bank employees and obtain information about ATM transactions. Finally, the attackers inject JavaScript code into the online store's servers where cardholder data is stored. If two-factor authentication via SMS does not exist at the time of purchase, fraudsters simply need to know the card's CVV code.

The most advanced form of online skimming is the practice of microtransactions. The organization may request the cardholder to make a test payment to confirm the reservation in order to validate the card. At the same time, the cardholder enters on the site (which may be a counterpart to the popular service) the data of his plastic, including the CVV code.

What is and what is the NFC technology of my cell phone for? Skimming devices?

Skimming uses a variety of card data readers. It all depends on the type of ATM or card reader.

make contactless payments with NFC Magnetic tape reader .- It consists of a small integrated circuit powered by batteries. Typically, the reader is encased in a plastic or metal case that mimics and sits over the actual card reader of the target ATM or other device. This component allows attackers to obtain information encoded on the card's magnetic stripe without blocking the actual transaction.

make contactless payments with NFC Hidden Video Camera .- Installed in or near an ATM, often disguised as promotional material. Allows you to read the user's PIN as they enter it.

make contactless payments with NFC Keyboard overlay .- It has the same purpose as a camcorder. It is an overlay on the actual ATM keypad and writes the PIN code when you enter it.

As many countries switched to chip cards, criminals adapted as well, and more sophisticated variants of skimmers began to appear. Some skimming devices are thin enough to fit into a card reader slot.

Skimmers can also be placed entirely inside ATMs, usually by corrupt professionals, or by drilling or cutting holes in the ATM lid.

make contactless payments with NFC Unknown ATMs .- The greatest danger for the user is unknown and street ATMs, especially those located in unlit areas - it is easier to install readers on them. It is better to use ATMs with anti-skimming or jitter pads installed. A jumpy card reader causes the card to vibrate slightly, which prevents fraudsters from recording information correctly.

The safest are ATMs located directly in bank branches. Such devices are regularly checked by the security service.

What is and what is the NFC technology of my cell phone for? What happens to the stolen data

The card's magnetic stripe stores information such as the plastic number, the card's expiration date, the cardholder's name, the service code (so that the cashier/terminal understands what functions the card has) and the verification code (similar to CVV). With this information, the scammer makes a duplicate of the plastic and accesses the card account. At the same time, you can withdraw money anywhere in the world until the account holder contacts his bank to block the card. In the absence of two-factor authentication, criminals can also make purchases from online stores.

he main danger of skimming is the imperfection of the legal framework for the protection of stolen funds due to information leakage. It will be difficult for the cardholder to prove in court that they did not actually withdraw money from the account.

Banks began issuing chip cards, which improved consumer security. Security researcher Brian Krebs explains: "Although data that is normally stored on the card's magnetic stripe is also copied onto cards with a chip, this chip contains additional security components that are not on the magnetic stripe." This means that thieves cannot duplicate an EMV chip, but they can use the data to clone a magnetic stripe or for other types of fraud

Kaspersky Lab confirms that chip cards can only be hacked under special conditions and with expensive equipment.

However, fraudsters have also adapted to the new conditions and have started using devices that are installed inside ATM card readers. This type of fraud is called "shimming." "Shim" is a thin, flexible plate that performs the same functions as a skimmer.

make contactless payments with NFC You must follow a few simple rules:

1.- Use those terminals and ATMs that are located directly in bank branches or other protected institutions.

2.- It is better to look for ATMs with antiskimmers.

3.- Do not use unknown ATMs.

4.- Before inserting a card in an ATM, inspect it .

5.- Do not tell anyone your PIN code, and when enter it, cover the keyboard with the palm of your hand.

6.- Do not give your card to strangers; do not store your data on public devices (for example, on office PCs); do not express this information over the phone if a "bank employee" calls.

7.- If the card is lost, immediately call the bank to block it; regularly check payment details in banking applications.

8.- Connect the SMS service-informing about card transactions .

9.- Issues chip cards only.

10.- Set a limit on the issuance of funds per day and per transaction.

11.- Abroad, withdraw money only at bank branches.

12.- If possible, use NFC on your smartphone by connecting Apple Pay, Samsung Pay, or Android Pay.

Note.- As an option< For additional security name="7" id="link8">, you can also install one of the "Skimmer Scanner" apps that checks Bluetooth transmissions to detect such devices.What is NFC technology and how to activate it
