On which models it works?

Before studying how to pay by card via phone Xiaomi, first of all it is necessary to clarify whether the mobile device supports this technology. Contactless payment on Xiaomi does not work in all models. To access the feature, you need to ensure that you meet a number of technical requirements:

  • Contactless payments will not be possible if there is no NFC module. With its help, the device creates a signal to transmit the necessary information to the receiving terminal. The absence of the chip indicates the impossibility of contactless payment for goods and services;
  • The second important point lies in the model. Generally, outdated versions do not allow access to the feature. In the case of Xiaomi, contactless card payment through the phone is supported on devices from the Mi line, starting with Mi 2A. Owners of smartphones of the popular Redmi Plus model will have to pay for purchases in the standard way;
  • The third requirement is to use strictly official software from the developers. Any tampering with it, like setting ROOT rights, limits access to the function.

One of the main reasons why the contactless payment Xiaomi Mi Mix 2S could not be set up, is the installation of third-party software on the smartphone.

How to use:

And finally, how to use Android pay on Xiaomi? It is necessary that the smartphone was on and was activated option NFC (it is sometimes turned off). If you have several cards in your wallet, you can choose the one to make the purchase with.

To pay successfully with NFC, you need to unlock the device and bring it to the terminal for 2-3 seconds until you see a message about the payment for the purchase and an image of a working card. Of course, sometimes the cashier may ask you to enter your PIN code and sign the receipt. It all depends on the settings of the bank that issued the card and the payment terminal.

  • If you have several cards connected to the device, one of them should be selected as a permanent card. To pay with another card, you need to open the application on your phone and select the card you want to pay with.
  • It is possible to pay with Android in some applications and sites. In these cases, the payment page will have a “Pay with Android Pay” button.

NFC allows you to use NFC to share information, just like you would use Bluetooth. But the transfer rate here is much slower. Therefore it is reasonable to transmit only small notes or contact cards. It uses Android Beam technology. It does not need to be installed separately, smartphones with the NFC module are present by default. But in some models you have to turn it on manually by moving the slider.

To transfer the files go to: “Settings” “Wireless networks” “NFC”. Check the box “Allow exchange of data when combining the phone with other devices. Start the file that is going to be transferred, put the smartphones with their backs to each other. Wait until a window appears on the screen inviting you to send the file. Confirm the transaction. In the same way, you can pass a list of contacts when you change phones.

Mi Pay system for Xiaomi

Mi Pay is a convenient and versatile payment service that allows you to make contactless purchases. It is in great demand and interest in China, but became known about it relatively recently in Russia. The principle is the same as when you pay by bank card, but with more protection. The mobile device imitates the data of a credit card attached to the service, and as a result, the payment terminal sees the smartphone as a card.

Now almost any store or supermarket uses a modern payment terminal that supports this technology. Let’s look at the benefits:

  • Now you only need to carry a mobile device, which easily replaces all cash and bank cards.
  • High time savings. The transaction process is several times faster, and you do not have to wait for the seller to collect and give the change from the purchase.
  • The subscriber can add several different banks to the system simultaneously and choose the desired account directly during the payment procedure.
  • Higher security level. The owner of a smartphone does not have to worry about the safety of money. Every purchase needs to be confirmed by entering a password or scanning your fingerprint.

Despite the simplicity of the general requirements to install, configure and use the application on Xiaomi, various difficulties may arise in private. If you faced one of these problems and successfully solved it, you can share your experience in the Комментарии и мнения владельцев.

A common cause of problems with the payment service in Xiaomi is the presence of an outdated version of the firmware on the gadget. To solve the problem, you just need to update the OS to the latest. In some cases, the updated firmware allows Android Pay to work even without locking the bootloader.

The installation of Magisk Manager (root-right administrator) allows to solve the problem with the root-right (the service works without turning it off). Tested with Android Pay on mi5s and mi5.
