NFC (Near Field Communication) technology has become an integral part of modern smartphones, allowing you to quickly pay for purchases, transfer files and connect to smart devices. However, not all Xiaomi Redmi 9 models are equipped with this module – it depends on the region of release and modification of the device. If you plan to use contactless payments or connect accessories via NFC, it is important to know in advance whether your phone supports this feature.
In this article, we’ll look at 5 reliable ways to test NFC on Redmi 9, from specs to hands-on tests with third-party apps. You’ll also learn which versions of Redmi 9 are exactly equipped with an NFC chip and which are not, and what to do if there is no module in the device. All methods are simple and require no special skills – just follow the step-by-step instructions.
1. Verification through phone settings
The fastest way to know if there is NFC is to look at the Xiaomi Redmi 9 system settings. The manufacturer usually hides the option if the module is not physically in the device.
- Open the Settings app (the gear icon on the home screen).
- Go to Connections and Sharing (or Wireless Networks in some versions of MIUI).
- Scroll down the list and find the NFC item.
If you don't have one, your Redmi 9 doesn't support NFC. If you have one but the switch is inactive, try turning it on. Note that some firmware may call it Contactless Payments or Mi Pay.
💡
If NFC-There is no option, but you are sure that your model should support it – update the firmware to the latest version MIUI. Sometimes the function is hidden due to software errors.
2. Analysis of the technical characteristics of the model
Not all versions of Xiaomi Redmi 9 are equipped with NFC-The manufacturer has released several modifications of the device for different markets, and their configuration is different:
| Model | Region | Support for NFC | Notes |
|---|---|---|---|
| Redmi 9 (M2004J19G) | Global version | ❌ No. | The most common modification for Europe and Asia |

| Redmi 9 Power (M2010J19SI) | India | ✅ Yes. | Redmi 9T for the Indian market |
Important: Even if your model is marked as NFC-supporting, check for the physical presence of the chip – some batches could be released without a module due to a shortage of components.
To accurately determine your modification:
- Open the Settings. → The phone.
- Find the model number (e.g. M2004J19G).
- Check the table above.
Visual inspection of the hull
NFC-The chip in Xiaomi Redmi 9 is usually located at the top of the back cover, next to the camera, and can be detected by the characteristic metal area under the plastic case:
- 🔍 Remove the cover – it can block the signal.
- 📱 Light the flashlight on the top of the back panel at an angle 45°. Look for a small rectangular contour (about) 1×1.5 centimeter).
- 🧲 Bring the magnet in — NFC-The chip contains metal elements and may be weakly attracted.
⚠️ Attention: Don't confuse NFC-chip with Wi-Fi antennas or GPS, which can also be seen under the body. NFC-The site is usually located closer to the center of the upper part, rather than at the edges.
It looks like NFC-chipboard?
4. Use of test applications
If the visual examination fails, install a dedicated NFC diagnostic application.
- 📱 NFC Tools (Google Play) – shows the presence of the module and allows you to test its operation.
- 🔧 CPU-Z — Sensors displays a list of supported sensors, including NFC.
- 🛠️ AIDA64 — detailed information about the hardware, including chip data NFC (if there is).
Instructions for checking through NFC Tools:
- Download and install the app from Google Play.
- Run it and wait for the loading.
- If the message “NFC not detected” appears, the module is not in the phone.
- If the app offers to enable NFC, your Redmi 9 supports the technology.
☑️ Checklist for testing NFC
⚠️ Note: Some apps (e.g. Google Pay) may show an error “Device does not support contactless payments” even if they have a contactless payment. NFC. This is due to a lack of certification for payment systems, not a hardware problem.
5. Verification through the Engineering Menu
For power users, there is a way to check through the hidden MIUI engineering menu, a method that requires caution, as incorrect actions can disrupt the phone.
Instructions:
- Open the Phone app.
- Enter the combination: ##4636###.
- In the menu that opens, select Phone Information.
- Scroll down to the RF Band Info section.
- Look for the NFC string – if there is one, the module is supported.
⚠️ Warning: Do not change any settings in the engineering menu unless you understand their purpose.This may result in loss of communication or resetting of settings.
💡
If the engineering menu doesn't open, your version of MIUI may block access, in which case use other verification methods.
What to do if there is no NFC?
If your Xiaomi Redmi 9 doesn’t support NFC, there are a few alternatives:
- 💳 Chip-enabled bank cards – most terminals support chip-free payment NFC.
- 📱 Outside NFC-Adapter – Connected through USB-C (For example, Sonoff Zigbee 3.0 USB Dongle Plus).
- 🔄 Exchange under guarantee - if NFC It is listed in the characteristics of the model, but is not physically present, this is a reason for the return.
- 🆕 Buying a new model – Redmi Note 11 or POCO X4 Pros have NFC basic.
You can also use it. QR-Contactless payment codes (via SberPay, Tinkoff Pay) or Bluetooth LE Connecting to smart devices (e.g. Xiaomi Mi Band).
