Xiaomi Redmi smartphones support several methods of contactless payment.

| Mi Pay | Built-in to MIUI, supports UnionPay cards, works without the Internet | Limited list of banks, difficulties with foreign card binding | Partially (UnionPay only) |
| SberPay | No need to unlock your phone for payment, integration with the Sbera Ecosystem | It only works with Sberbank cards. | Yes. |
| Banking applications (Tinkoff, VTB, Alfa-Bank) | Instant payments, bonuses and cashback, not dependent on Google/Mi | You need to install a separate application for each bank. | Yes. |
For most users in Russia, the best choice is Google Pay or a banking application (if you have a single bank card). Mi Pay is only relevant for UnionPay cards or in Asian countries. If you have Redmi on Chinese firmware, Google Pay may not work, you will need to unlock the bootloader and install global software.
