How to know if there is NFC in the phone Xiaomi Redmi Note 7: all ways to check

Xiaomi Redmi Note 7 is still one of the most popular budget smartphones, but the question is about the availability of the smartphone. NFC-The thing is, the manufacturer has made this model in different versions, with and without a chip, and if you're planning to use your phone for contactless payments, smart devices or data, it's important to know if your phone supports this technology.

In this article, we’ll look at 5 reliable ways to test NFC in Redmi Note 7, including visual inspection, software methods and technical specification analysis, and learn which versions of the phone were equipped with the module, why it could be turned off in firmware, and what to do if NFC is available but not working, and information is relevant for all regions, from Europe to Asia, where configurations may have differed.

1. Model Labeling Check: Which Redmi Note 7 Versions Support NFC

The fastest way to determine whether you have NFC is to look at the exact model of your phone. The manufacturer has released the Redmi Note 7 in several versions, and only a few of them are equipped with a chip.

• 📱 Redmi Note 7 (lavender) - basic global version without NFC (most common in Russia and CIS).
• 📱 Redmi Note 7 Pro (violette) - version with improved camera, but also without NFC.
• 📱 Redmi Note 7S (Lavender - Indian modification, NFC absent.
• 📱 Redmi Note 7 (lavender) for Europe – a rare version NFC, labeled M1901F7G or M1901F7H.

To find out your model:

1. Open the settings → About the phone → Model.
2. Remember or write a code (e.g., M1901F7G).
3. Compare it to the table below.

⚠️ If your phone is bought in Russia or the CIS, there is a 99% probability that it does not have it. NFC, Even if the seller said otherwise, the exception is the devices that were brought in from Europe officially.

2. Visual inspection: where to look NFC-antenna in Redmi Note 7

NFC-The chip in smartphones is usually located under the back cover next to the camera or battery. In Redmi Note 7, the antenna (if any) is located at the top of the case, under a metal frame:

1. Remove the case and inspect the top of the phone (above the display).
2. Hold the phone to the light source at an angle – sometimes the antenna contours are visible as a thin grid.
3. Try to attach another one. NFC-device (e.g. bank card) to this area – if there is a chip, vibration or sound may appear.

The photo below shows the typical location of the antenna in the European version of Redmi Note 7:

If you didn't see the antenna, it doesn't mean it's not there -- in some batches, it could have been hidden under a layer of plastic -- but in 90 percent of cases, visual inspections give you accurate results.

3. Verification through Android Settings: Where to Search for NFC in the Menu

If NFC-There's a chip in the phone, you can turn it on through system settings. In Redmi Note 7, the path to the option depends on the version. MIUI:

• 🔧 MIUI 10-12: Settings → Connections and sharing → NFC.
• 🔧 MIUI 13+: Settings → Wireless networks → Additionally. → NFC.

If the NFC item is not on the menu, it can mean:

• ❌ The phone is physically missing a chip.
• 🔄 The option is hidden due to regional restrictions (for example, in firmware for China).
• 🛠️ NFC Disabled at the core level (solved by flashing).

Open "Settings" | Find the "Wireless Networks" or "Connections" | Flick to "NFC" | Try to turn on the slider

⚠️ Note: Some custom firmware (for example, LineageOS) NFC It can be displayed in the menu but not work due to lack of drivers.

4.Use of third-party applications for NFC diagnostics

If the system settings do not give a clear answer, install one of the specialized applications for checking hardware.

• 📲 NFC Check (by TagInfo) – shows the presence of the chip and its model.
• 📲 NFC Tools – Tests the reading/writing of tags, even if the option is hidden in the MIUI.
• 📲 AIDA64 — in the Sensors section → NFC displays the technical data of the module.

Example of the report from AIDA64 for the Redmi Note 7 with NFC:

NFC Controller: NXP PN547




Firmware: 1.0.2




Supported Protocols: ISO 14443-4, MIFARE, Felica

If the app shows NFC: Not available or a similar error, there is no chip in the phone. Note: some programs may give a false positive result on firmware with NFC emulation (for example, for contactless payments via HCE).

💡

Before installing apps, check reviews – some require root rights or show ads masquerading as scan results.

5. Testing by contactless card or other NFC-device

The most reliable way to test NFC performance is to try to read data from a bank card, transport ticket or other smartphone.

1. Enable NFC in the settings (if there is a paragraph).
2. Open the NFC Tools app or Google Pay.
3. Hold the phone back to the card (distance < 2 cm).
4. If the chip works, a tag detection notification will appear.

What to do if there is no reaction:

• 🔋 Check if the battery is under 15% low – some phones are turned off NFC low-charge.
• 📶 Make sure there is no foil on the card/device (it blocks the signal).
• 🛠️ Try to reboot your phone – sometimes the driver NFC "hanging".

⚠️ Attention: If the phone vibrates when you approach the card, but it doesn't read the data, the problem may be the firmware. EU-version MIUI or installing a custom core with support NFC.

6.Serial number and IMEI check: Xiaomi online services

The official website of Xiaomi allows you to check the configuration of the phone by IMEI or serial number.

1. Find IMEI in Settings → About Phone → General information or on the box.
2. Go to the Xiaomi authentication page.
3. Enter IMEI and CAPTCHA.
4. Find the NFC Support line in the results.

Important: Xiaomi may not show NFC information for older models (including the Redmi Note 7), in which case, refer to alternative databases such as GSMArena or DeviceSpecs.

7.What to do if the NFC in Redmi Note 7 doesn't work (although it should)

If all checks have confirmed the presence of a chip, but it does not function, the reasons may be as follows:

• 🔧 There are no drivers - relevant for custom firmware.
• 📱 Hardware failure – damage to antenna or plume.
• 🛡️ Blocking the region - some firmware is turned off NFC for Russia/CIS.

Decisions:

1. Update MIUI to the latest version via Settings → System Update.
2. Install. EU-The firmware (e.g. xiaomi.eu) is in them. NFC unlocked.
3. Check the antenna at the service center - it could be damaged during disassembly.

💡

If the NFC stopped working after falling or getting moisture, don’t try to repair yourself – the chip is static and easily damaged.
