How to check for NFC in Xiaomi phone: from settings to tests

Why you need NFC and how to find it in Xiaomi

NFC (Near Field Communication) technology has become an integral part of modern smartphones, allowing you to quickly exchange data, pay for purchases and connect accessories. In Xiaomi phones, this module is not found in all models – its availability depends on the price category, sales region and even a specific modification of the device. For example, the budget Redmi 9A or Poco M3 do without NFC, while the flagship Xiaomi 13 Pro or Mix Fold 3 are equipped with it by default.

The problem is that the manufacturer doesn’t always focus on this chip in marketing materials. Users often find themselves buying a phone for contactless payments and then discovering that the module simply doesn’t exist. This article will help you figure out how to accurately determine the presence of NFC in your Xiaomi smartphone without parsing the case — from checking through menus to using third-party utilities and analyzing technical specifications.

Method 1: Checking through phone settings

The quickest way to know if NFC is available is to look at the system settings. In most Xiaomi models (based on MIUI 12 and newer), the path is as follows:

1. Open the Settings app (cog icon).
2. Go to Connections and Sharing (or Wireless Networks in older versions).
3. Scroll down to the Other Wireless Connections block.
4. Look for an NFC switch – if you have one, the module is installed.

On some devices (such as Xiaomi 12T or Redmi Note 11 Pro+), the NFC item may be hidden in the submenu Additional or More. If you don't find it in the first section, try searching for settings - type "NFC" in the bar at the top of the screen.

💡

On MIUI Global phones, the menu item name may be different from the Chinese firmware version. If you don't find NFC in Connections, check the Special Features section, and sometimes the chip is activated there.

Important: even if you have an NFC switch, it doesn’t guarantee that it will work. On some models (for example, the Redmi Note 10 Pro for India), the module is present in the settings, but does not function due to regional restrictions, in which case only firmware with NFC support or buying another version of the device will help.

Method 2: Analysis of technical characteristics

If you haven’t bought the phone yet or want to check the details before buying, check the official specifications. Xiaomi publishes full specs on its website, but there are nuances:

• 🔍 Official website: Go to the model page (e.g. Redmi Note 12 Pro) and find the Wireless Technology section. NFC will be specified by a separate paragraph.
• 📄 Documentation: in the box with the phone should be a brochure with technical data - look for a mention NFC Near Field Communication.
• 🛒 Marking on the box: some models (e.g. Poco) F5) have a list of supported technologies, where NFC It can be indicated by the contactless card icon.

Note regional differences: For example, the Xiaomi Mi 11 Lite for Europe is equipped with NFC, while the Asian version (with the index 5G NE) is not. To make no mistake, check the model number (located on the sticker under the battery or in the settings on the path About Phone → Model) and check it against a database, for example, on GSMArena.

Method 3: Visual examination of the phone

If you don't trust the software, you can try to find the NFC antenna physically, and most Xiaomi smartphones have it on the top of the back, right next to the camera, and you can see the signs of it.

• 📱 Metal plate: a small metal circuit (size) can shine through the glass panel ~2×3 centimeter).
• 🔄 Symmetrical location: The antenna is usually duplicated on both sides of the body for better reception.
• 🛠️ Disassembly: when removing the back cover (not recommended without experience!) NFC It looks like a small chip with a sign. NXP or PN547.

Warning: Don’t confuse the NFC antenna with the wireless charging module! the latter is usually larger and centered. In addition, in some models (for example, Xiaomi Mi 11), the antenna is hidden under the decorative panel and not visible to the naked eye.

⚠️ Note: If you decide to take apart your phone for check-up NFC, Remember, this is a security issue. In models with adhesive back mounts (e.g. Xiaomi). 12S Ultra) high risk of damage to plumes. For accurate diagnosis, it is better to use software methods.

Method 4: Test applications for testing NFC

If you have a module in your settings, but you doubt it will work, install one of the specialized applications, which will not only confirm the presence of the chip, but also test its functionality:

• 📱 NFC Tools (Play Market): shows the status of the module, allows you to read and write tags, Suitable for checking compatibility with payment systems.
• 🔍 NFC Check: a minimalist utility that only gives two options — «NFC supported" or «NFC not supported».
• 💳 Google Pay: If the app offers to add a card, it means NFC It works and supports contactless payments.

Instructions for using NFC Tools:

1. Download and install the app from Google Play.
2. Open it and click Reading (Read).
3. Bring the phone to anyone. NFC-tag (for example, a bank card or a tag in a store).
4. If a notification of the detection of the tag appears, the module is serviceable.

Note: on some firmware (e.g. custom LineageOS) applications may not see NFC due to lack of drivers, in which case only flashing to official MIUI will help.

Method 5: Checking through the Engineering Menu

For advanced users, there is a hidden engineering menu diagnostic method that works if NFC isn't displayed in the settings, but you suspect it. Careful: the wrong actions on this menu can disrupt your phone!

Instructions:

1. Open the Phone app.
2. Enter the code ##4636##
3. In the menu that opens, select Phone Information.
4. Scroll down to the RF Band Information block.
5. Look for the NFC string – if there is one, the module is installed.

On some models (e.g. Xiaomi Mi A3 with pure Android), the path may be different.

##284##

⚠️ Warning: The engineering menu contains parameters critical to system stability. Do not change the values in the Modem or Hardware partitions unless you are sure of their purpose.

What to do if NFC is available but not working

The situation where the module is detected but not functioning is more common than it seems, the reasons can be both software and hardware:

• 🔄 Resetting settings: go to Settings → The phone. → Reset and select Network Reset. That will return the settings. NFC factory-wise.
• 📱 Update firmware: check the relevance of the software in Settings → Update the system, in older versions. MIUI (11) NFC Could have been shut down by bugs.
• 🛠️ Antenna damage: If the phone fell or came into contact with water, the module plume could be damaged.
• 🔒 Regional restrictions: on some models (e.g. Redmi) K50i for India) NFC Software blocked. Solution - Global firmware ROM.

If the problem persists, try testing NFC with another device, such as holding your phone to an in-store payment terminal or another smartphone with NFC enabled, and a lack of response is likely to indicate a hardware malfunction.

💡

Before visiting the service center, check if the NFC is disabled in the security settings (Site "Additional settings → Privacy").
