Pros and Cons of NFC technology?
Near Field Communication (NFC) is a short-range wireless data transmission technology. 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.
What is NFC technology and how to use it?
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.
NFC supports three modes of use:
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.
NFC technology specificationsIn 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.
Ways to use NFC technology
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.
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 used for?
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.
To make payments with the mobile phoneNFC 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.
To identify yourself with the mobileNFC 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.
For mobile tradingCompanies 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.
For transportation with the mobile phoneNFC-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.
For the protection of the car with the mobile
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.
Identification and Access ControlNFC 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.
For medicine with the mobileNFC 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.
To play with the mobile
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:
For Internet systems (IoT) with the mobileIoT 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.
NTF technology in mobiles?
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.
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.
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.
3.- Open the tone of notification by swiping from the top of the screen. Among the icons of available features, look for three precious letters. There you can quickly activate this option.
Will NFC work on mobile?
Cómo usar NFC en AndroidThe 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.
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.
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.
How to use NFC on iPhone?
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.
How to enable NFC on your cell phone?
Buying a phone with an NFC module is half the battle. Next, you need to know how you can activate the module to perform the necessary operations. Activating this option is very simple.
This can be done in two ways:
1.1.- See the phone configuration.
1.2.- Go to the menu item "Wireless networkss".
1.3.- Next, select the "More" subsection, where the NFC function.
1.4.- All you have to do is activate it.
2.- The second option to enable NFC is to use the notification tone. In it, you need to find the desired icon and just tap on it. Activation will be confirmed by a color change.
If your smartphone has an NFC chip, then to enable the data exchange function or make a payment transaction, you will need to activate a special application - Android Beam. It can be found in the settings under the "Advanced" tab.
Payment with Android Pay and NFCTo select a phone as the main payment instrument with NFC. download the Android Pay utility.
Google Pay is the fast and easy way to pay in millions of places: online, in stores and many more. It offers you everything you need to process your purchases and keeps your data safe. In addition, you can manage your account both on the website and in the application.
Shop smarter. Google Pay lets you store everything you need to speed through checkout with your phone. In addition, the “Home page” tab offers you all the information you need at the moment
Download Android Pay for Android
To work with Android Pay
1.- Download the official Android Pay application from PlayMarket.
2.- Run it on the device.
3.- Select Scan map. Scanning is done through the smartphone camera. In the presence of errors, it is always possible to enter the information manually.
4.- An SMS is sent with a confirmation code for the link to the phone attached to the "plastic strong>".
The application allows you to enter the data of several plastic cards at once, and the user simply selects the required one when paying.
Using a smartphone equipped with the NFC function, you can pay for purchases in the store. You can set the module to work automatically. To do this, do the following:
1.- In the settings, go to the "One touch payment" section and select Android Pay as the default payment method.
2.- Allow the application to start automatically at system startup.
It is important that the terminal has a contactless payment function. Also, when making a payment, there is a limit on the amount. If the purchase at a cost does not exceed 900 rubles, confirmation in the form of a pin code is not required card. If the amount is exceeded, the user is also required to enter a PIN. Additionally, it can be requested when making more than 4 consecutive payments.
Security in NFC technology?
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.
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.
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.
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.
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.
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.
Skimming devices?Skimming uses a variety of card data readers. It all depends on the type of ATM or card reader.
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.
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.
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.
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 happens to the stolen dataThe 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.
How to avoid being a victim of skimming?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.
Pros and Cons of NFC technology?
Advantages of NFC technology
1.- It has a high data transfer rate.< br />
2.- For example, payment with your help occurs almost instantly .
3.- The smartphone is becoming the main theme of our life.
4.- Replaces a lot of tools, documents, bonus cards and now also wallets.
5.- Having a device of this type with a bank card connected, it's not scary to leave home without a wallet.
6.- The use of technology for label programming allows you to significantly save time in performing monotonous operations.
7.- Many of them are replaced by taking the smartphone to the mark The use of NFC technology with official applications allows you to carry out payment transactions with a high level of protection.
8.- After all, information is transmitted over a distance of up to 10 cm, so it is difficult for an attacker to intercept it to go unnoticed.
9.- When making financial transactions through NFC, it is created a conditional account in which bank card details are not entered.
10.- All information is stored on the system server. This is additional protection of client funds.
