Owners of Xiaomi Redmi 9A often face confusion around the NFC feature — some believe that the budget model does not have it at all, others can not find the settings on the menu. In fact, the situation is ambiguous: officially Redmi 9A (model M2006C3LG) is not equipped with a hardware module NFC, but there are regional versions and methods of circumventing restrictions. In this article, we will examine all the nuances, from checking the presence of the chip to alternative ways to use contactless technologies.
It's important to understand that the NFC in Redmi 9A is a lottery feature. The manufacturer saves on budget models, so even on identical-looking smartphones, one can support the technology and the other can't. We analyzed data from the 4PDA and Mi Community forums, and we tested workarounds. If your device is not equipped with a chip, at the end of this article you will find the current ways to emulate NFC through third-party devices.
Verification of availability NFC-module 9A
Before you try to turn on NFC, make sure your Redmi 9A is physically supportive of the technology.There are 3 reliable ways to check:
- 🔍 Visual inspection: Remove the back cover (if possible) and look for a small metal board next to the battery. NFC-chip is usually labeled as NXP PN547 similarly.
- 📱 Testing through the Engineering Menu: Enter the code ##4636## in the phone application, then go to Phone Information → Hardware information. Item NFC It should be shown as Supported: True.
- 🛠️ Check through AIDA64: Install the application from Google Play, open the System section → Chipset, strings. NFC Controller confirms support.
If none of the methods showed a module, your Redmi 9A is not equipped with NFC at the hardware level, in which case move to the section on alternative solutions. Importantly, some sellers deliberately mislead by indicating NFC in the characteristics for the M2006C3LG model is a marketing hoax.
⚠️ Note: In the forums there are tips to ask NFC-Fastboot module. This is a fraud! The hardware part can't come back after the firmware is in place -- it requires a physical replacement of the motherboard.
Step-by-step instructions for turning on NFC (if there is a module)
If the check confirms the presence of a chip, follow this instruction. In MIUI 12/13/14, the path to settings may differ, so we will give a universal algorithm:
- Open Settings → Connect and share (or Wireless Networks in older versions).
- Scroll down to the Additional (may be called More) item.
- Slip on NFC – if there is no item, use the search by settings (the magnifying glass icon at the top).
- Activate the NFC switch and select the mode of operation: Read only - for scanning tags; Card mode - for contactless payments; P2P - for data exchange between devices.
Once activated, the status bar will show an icon N. If it is not, restart your smartphone. To check whether you are working, download the NFC Tools app from Google Play and try counting any contactless card (for example, a transport or bank card).

Configure contactless payments via NFC
To use Redmi 9A as a means of payment, you will need to:
- Install Google Pay (or Mi Pay for China) from the official store.
- Add a card with Mastercard Contactless or Visa PayWave support.
- In NFC settings, select Card Mode and link the Google Pay app as the default handler.
- Verification through SMS or banking application.
To minimize the risks:
- Turn off NFC in settings when not in use.
- Set a limit on contactless payments in the banking application.
- Use Google Pay with virtual cards instead of the main one.
⚠️ Attention: B MIUI There is a vulnerability (patch was released in version 14.0.5), which allows you to bypass the screen lock through the screen. NFC. Update your firmware if you use contactless payments!
