| NFC Check | Direct check of availability and performance NFC-chip | Download | "NFC not supported" |
How to use NFC Check:
- Install the application and open it.
- Press Check NFC.
- If an NFC message is not supported, there is no module.

6.Frequent NFC Mistakes and Myths in Redmi 9A
There is a lot of incorrect information about NFC in Xiaomi budget smartphones on the Internet.
- 🔄 "NFC The engineering menu (#4636##) only shows existing modules, but does not add new ones.
- 📲 "After updating MIUI appear NFC" — Firmware doesn't add physical components.
- 💰 "Paid applications activate hidden applications NFC" — No legal software can enable a non-existent module.
- 🔋 "NFC It's turned off to save the battery. "" It's not true. If the module isn't there, you can't turn it off.
Another common case is that users confuse NFC with other technologies:
- Bluetooth – for data transmission at a distance of up to 10 meters.
- Wi-Fi Direct – for sharing files without a router.
- Infrared port (IR) – for control equipment (there are some Xiaomi, but not Redmi 9A).
If you've met the advice of "switching the phone to activate NFC," it's dangerous.
- Break the phone.
- Deprived of the guarantee.
- Adding vulnerabilities to the hack.
💡
NFC is a hardware module, like a camera or a speaker, and you can't add it in software, like you can't turn on a flashlight if you don't have an LED in your phone.
