In this article, we will analyze all the steps of NFC configuration โ from checking hardware support to linking cards to Google Pay, SberPay and other services.
Itโs important to understand that Redmi 9T came in a few versions, and not all of them are equipped with an NFC chip. Weโll show you how to check for a module without disassembling your phone, and also explain why even if it is available, payment may not work (spoiler: firmware, region or bank are to blame). If you have already tried to set up contactless payments and got an error, at the end of the article there is a section with solutions to 90% of typical problems.

Once activated, the system can request a reboot, you can agree. If there's no "NFC" on the menu, it means:
- ๐ You donโt have a global firmware (you need to re-flash it).
- ๐ Module NFC Disabled at the core level (solved by root rights).
