What is easier and safer: pay the old way with cash or card, or make purchases with systems like Apple Pay or Android Pay?
Apple Pay, Android Pay, and other contactless payment methods that don't require a bank card have become a part of everyday life. People pay with devices, they will rarely find a terminal that does not support these payment systems. However, many still wonder:

How safe is it to pay with my mobile?
"What if my phone is taken from me?" - Many ask this question when they hear about contactless payment. However, in the first place, your wallet may be taken away, where the money is. And secondly, it is the loss or theft of the phone that is a much safer incident from a fund safety point of view.

Understand that enabling Apple Pay on your phone requires setting a PIN to unlock your phone. The phone in sleep mode will be locked anyway, and those who don't know the pin code won't even be able to unlock it. In addition, each procedural payment must be confirmed.
Banks also provide additional security. Of course, not all banks are willing to solve controversial problems, however, the chances of getting your money back are much higher than if they simply stole your Wallet with money. In case of illegal debit of funds, you can write a statement both to the bank's security service and to the police.

Paying for your purchases with Apple Pay is more secure than card payments. If you lose your card, intruders can make small transactions that do not require entering a PIN code. And in some cases, knowledge of the card details and the secret code will suffice. At the same time, to block the card, you need to call the bank and the phone is paired with a default PIN code.

As for Apple Pay, even physically owning a phone doesn't make it easy to steal your money. Also, you can permanently lock the stolen phone yourself remotely; then it will not be possible to unlock it even with a PIN code,
As for Android Pay, when you enable this feature on Android smartphones, the security systems are also forcibly activated. You will need to install a pin code and also Android Pay cannot be enabled on "rooted" smartphones

How does mobile phone payment work?
The advantages of paying with Apple Pay or Android Pay is that you don't need to carry your money or card with you. All you need is a gadget that you will pay with. At the same time, I managed to pay, for example, for gasoline at gas stations with Apple Watch, when the phone was accidentally forgotten in the car. Internet access is also not required (this is the difference between Apple / Android Pay and payments using banking apps and NFC chips on Android smartphones).

Mobile phone payment works like this. The vendor (or a ticket / drink / fast food vending machine) initiates the payment and asks you to insert a card or attach it to the terminal. If you have an iPhone (not X), press the Home button twice and put it in the terminal.
Paying online (where available) with Apple Pay is also helpful because you don't have to share your credit card information with all sites. However, in this case, you can also use Money or PayPal accounts with a bank card linked to them.

Conclusions of why pay with IPhone?
Contactless payments are fast and secure. Don't listen to horror stories about severed fingers; firstly, a severed finger cannot be unlocked, at least an iPhone.
Secondly, there has not yet been a single such incident. But the wallets really are constantly being stolen, and it is not that difficult to copy the bank card details. So if you are worried about your money, it is better to use contactless payments and not to use bank cards (PayPass, PayWave), but to use gadgets on IPhone.

How to use NFC correctly?

For practical use, it is important to know how to use NFC. The instructions for use are fairly straightforward, but differ depending on the application. So, to pay for purchases with the correct settings, it is enough to enable the NFC option on the phone and take it to the terminal. The payment will be made automatically.

To transfer data, you need to activate the option on both devices and then perform the following steps:
1.- Select the desired file in one of them and bring them back to each other.
2.- After the sound notification about device connection, press the screen to confirm the file transfer.
3.- Wait for the end of the transmission, which will also be indicated by a sound signal.

Note.- The distance between the devices should not exceed 10 cm. To scan the tag, you need to enable the option on the phone and zoom in. To program the tag, you need to download a special application, for example, NFC Tools

Where else can NFC be applied?
The application of NFC technology is observed in many areas. Several main areas can be distinguished.

A.- Data transfer First, we will focus on data transfer. Also, this can be done with almost all types of files. For example, a user can transfer an image, a text file, or even a movie to another device. The only downside in this case is that you have to keep the phones close to each other. This can be time consuming when transferring large files.
Also, application transfers are allowed. In this case, you don't have to search for them in the Play Store, you just need to activate the function and transfer the file to another phone. The same applies to games, links to certain sites. The only thing that users are limited in this case is the data transfer rate (and also the need to adhere to a certain distance).

B.- Scan marks and programming
Another useful feature that the technology is associated with is the use of custom labels. These are small objects that can be attached to any surface or carried with them (in pockets, backpack). The phone automatically scans the labels, but you must create them first.

The general sequence of actions is as follows:
B.2.- It is configured by means of special software (that is, the actions that the phone will perform when approaching the label are prescribed). For example, the phone automatically switches to silent mode.
B.3.- The label (physical medium) is placed where it is needed according to the functions it will perform.

Note.- With this feature, you can program a tag to switch the phone to silent mode and then place it on the desk. After that, whenever the phone is close to the tag, no one can disturb the user. At the same time, after the work is finished, the phone will automatically switch to normal mode.

C.- How to share NFC files.
If you want to exchange files between your Huawei device (in this case, the P Smart) and another mobile phone, you can use the NFC standard. To do this, you must first enable NSF and also activate Android Beam. Then go to Settings> More> NFC> Android Beam. After that, just bring 2 mobile phones closer and select NFC to share your file.

D.- How to configure contactless NFC payment
Today, there is a real boom in the development of contactless payment systems. The user does not need to take out a plastic bank card every time he needs to buy something or pay for services. You only need to bring the phone with the NFC module turned on and the configuration done for the payment process to be successful.

In order to pay with your Huawei P smartphone, you need to do 3 things:
D.1.- ºThe activation of NSF can be done in two ways: in the quick start panel of the application and through "Settings". In the first case, swipe down to lower the notification curtain and click on the NFC icon. In the second, you must go to: "Settings"> "Device connection"> NFC. Here, set the switch to the "On" position. Another mandatory item in this menu is "Default payment application". But until special programs are installed on the phone, there will be nothing to choose from.
D.2.- The Google Pay installation is the second step to configure your Huawei smartphone. Download this app from Google Play Store, install it as standard. When the process is complete, you need to go back to the settings menu and open the "Default payment application" submenu. If in the first step (see above) the list was empty, it should now show "Google Pay". This is the application and you must choose.
D.3.- You can link a bank card through the Google Pay settings. When the application starts, the configuration process begins:
D.3.1.- On the initial screen, click on the "Add card" button.
D.3.2.- A scanning window will open. You can scan the card with a smartphone camera or enter data manually.
D.3.3.- After completing the billing information, click on the "Continue" button.
D.3.4.- In the next window, accept the terms of use of the service by clicking the "Accept" button. After that, you need to confirm your bank details via SMS with a confirmation code.
D.3.5.- The code received in the message must be entered in the field provided for this and click on the "Send" button.
