Technical requirements and compatibility of Xiaomi devices
To make contactless payments successful, your smartphone must meet a number of specifications, including the NFC (Near Field Communication) module, which allows you to transfer encrypted data to the terminal at a distance of several centimeters.

⚠️ Note: If your Xiaomi model specifications do not include a module NFC, It is technically impossible to make payment by attaching a phone to the terminal, in which case the only option is to pay for the terminal. QR-code.
The operating system also plays an important role in the setup process. Most payment solutions require an up-to-date version of Android, usually at least 6.0, to work correctly, although modern services require more recent versions to ensure the proper level of security. Xiaomi regularly releases MIUI shell updates that can affect the work of system security services.
Another important aspect is the device region and firmware version. Global versions of smartphones tend to have a full set of necessary certificates for working with banking applications. Chinese versions (CN) flashed on global software may face limitations or unstable communication modules.
NFC configuration and basic security parameters
The first step to successful payment is to activate the payment correctly. NFC-Go to the settings of the smartphone and find the section responsible for the connections and general settings of the network.
The system will offer several uses for the technology: card emulation mode, read mode or P2P mode. To make payments, you need to choose card emulation, which allows the smartphone to simulate a physical plastic card when you bring it to the terminal.

When choosing a security feature, give preference to HCE, as this provides better compatibility with most banking Android apps.

The main payment method for Tinkoff customers on Android devices is to use their own Tinkoff Pay app or the main banking application. After installation and authorization, you need to add your card to the payment section.
The app creates a virtual token of your card, which is then transferred to the terminal, which means that the real plastic data is not transmitted to the seller, which greatly improves the security of the transaction, and in the application settings, you can select the default card that will be offered for payment.
Settings → Applications → Tinkoff Pay → PermissionsMake sure the app is given all the necessary permissions, especially to work with NFC and access geolocation (if required to confirm transactions).Sometimes, the Android system may restrict the background operation of the app to save energy, leading to payment failures.

Payment security and data protection
Financial security when using a smartphone depends not only on the technology of the bank, but also on the actions of the user. Using public Wi-Fi networks to make payments can expose your data to the risk of interception.
Check the active session list on the bank app regularly. If you notice a device you don't recognize or a session from another city, terminate it immediately and change the login password. Two-factor authentication should be enabled at all times.
Do not install applications from unknown sources, especially those that promise to “improve” NFC or give access to paid features for free.
⚠️ Warning: Never share codes from SMS or push notifications with third parties, even if the caller is a bank employee.
If you lose your phone, contact your bank immediately to block your cards and use Google or Xiaomi’s Find Device feature to remotely clean your data, which will prevent unauthorized access to your finances even when your screen is unlocked.
