NFC in Xiaomi Phone: How to Turn On, Configure, and Use It to the Maximum

NFC (Near Field Communication) is no longer exotic — it’s now embedded in most Xiaomi smartphones, from budget Redmis to flagship Mis and POCOs. It can pay with a single touch, exchange contacts, manage smart devices, and even automate routine tasks. But many users still don’t know how to activate hidden NFC features on Xiaomi or believe that the chip works only for contactless payments.

In this article, we will learn how to check for support. NFC In your model, where is the module, how to set it up for different tasks, from Google Pay to tag readers, and also talk about little-known features, such as how to use a phone instead of a transport card or how to create your own. NFC-If you think your Xiaomi doesn’t support the technology, don’t be too upset: sometimes the problem lies in firmware or regional restrictions.

How to know if there is NFC in your Xiaomi smartphone

Not all Xiaomi models are equipped with an NFC chip — especially for the budget line of Redmi and older devices. To avoid wasting time looking for a feature in the settings, check the specifications first.

The quickest way is to look at the labels on the box or in the documentation, and look for signs like NFC supported, Near Field Communication, or a wave icon, and if there's no box, use one of these methods:

• 🔍 Search by model: Enter your smartphone name (e.g. Redmi Note 12 Pro)+ 5G) + "NFC" Official Xiaomi websites or GSMArena reviews usually contain accurate information.
• 📱 Check through Settings: Open Settings → Connections and sharing → NFC. If there is no point, there is no chip in the device (or it is disabled at the firmware level).
• 🛠️ Diagnostics via the engineering menu: enter the code ##4636## in the Phone app, then go to Phone Information and search for the line NFC.

Note that even if NFC is specified in the specifications, the feature may be blocked in some regional versions of the firmware (for example, in Indian or Chinese models), in which case the flashing to the global or European version of MIUI will help.

Wherever NFC-The chip in Xiaomi phone and how it works

The NFC module in Xiaomi smartphones is usually located at the top of the back cover, next to the camera. The exact location can be determined by a small pictogram with waves (some models do not). It is important to know the location of the chip to properly attach the phone to the terminal or tag - the distance between the devices should not exceed 4-10 cm.

The technology operates at 13.56 MHz and supports three modes:

• 💳 Card emulation: The phone behaves like a contactless bank card or transport ticket (used to pay via Google Pay, Mi Pay or SberPay).
• 📱 Read/write: A smartphone reads data from tags or other devices (e.g., to automate tasks via Tasker).
• 🔄 Peer-to-Peer (P2P): Data exchange between two phones (contacts, links, files).

The NFC data transfer speed is low (up to 424 kbps), but it is enough to transfer small amounts of information, the main advantage being minimal power consumption and instantaneous connection without passwords.

💡

If NFC doesn’t work when paying, try removing the case – some materials (metal, thick plastic) block the signal.

How to enable and configure NFC on Xiaomi: step-by-step instructions

Activation of the NFC module takes less than a minute, but there are nuances depending on the version of MIUI. In new firmware (starting with MIUI 12), the path to settings is simplified, and in old ones, additional configuration may be required.

Follow this algorithm:

1. Open the settings (cog icon).
2. Go to Connections and Sharing (in some versions, Wireless Networks).
3. Slip on NFC.
4. Activate the slider Use NFC.
5. When you first turn on, the system may offer to download additional components (for example, for Google Pay) – agree.

After activation, we recommend setting the parameters:

• 🔄 Android Beam: Enable this option if you want to transfer files between devices (only works on Android until version 10).
• 💳 Default payments: Select your preferred app (Google Pay, Mi Pay or Banking).
• 📲 Reading Notifications: Useful for Debugging Labels.

Is the module enabled in the settings?

Is there a payment app (Google Pay, Mi Pay) installed?

Is NFC allowed for the right applications?

Have you tried removing the cover before using it?

If NFC is not working after turning on, restart your phone or check if the power saving mode is blocking the function. In extreme cases, reset your network settings (Settings → System → Reset → Reset your Wi-Fi, mobile network and Bluetooth settings).

How to use NFC on Xiaomi: 5 practical scenarios

Most Xiaomi owners only use NFC for contactless payments, but the technology is much more than that.

1. Contactless payments via Google Pay, Mi Pay or SberPay

To pay for purchases by phone:

1. Install the app (Google Pay, Mi Pay or Bank).
2. Add the card by following the instructions on the screen (confirmation via SMS or client bank is required).
3. When paying, unlock your phone and bring it to the terminal (no need to open the application).

Some Xiaomi models (such as the Mi 11 or Redmi K50) support payment even when the screen is off – just double press the power button.

2. Transfer of files and contacts between telephones

For data exchange:

1. Enable NFC and Android Beam on both devices.
2. Open the file (photo, contact, link) you want to transfer.
3. Hold the phones back to each other.
4. Wait for the beep - the transmission will start automatically.

Limit: The maximum file size is about 1 MB. For larger volumes, it is better to use Mi Share or Bluetooth.

3.Use of NFC-tagging

With tags (costs from 50 rubles), you can run scripts with one touch.

• 🚗 In the car: attach the phone to the tag on the panel – Bluetooth automatically turns on, the navigator starts and Wi-Fi turns off.
• 🏠 Home: The tag at the door turns on the "Home" mode, connects smart lamps and turns off mobile data.
• 🛏️ At night: the label on the nightstand puts the phone in silent mode and starts the alarm clock.

Use Trigger, Tasker or NFC Tools to set up.

Emulation of transport cards (Troika, Strelka, Metro)

In some regions (Moscow, St. Petersburg, Kazan), Xiaomi can be used instead of a transport card.

1. Download the official transport application (for example, Metro Moscow).
2. Link the virtual card to the phone.
3. When passing through the turnstile, unlock the screen and bring the phone to the reader.

5. Managing smart devices

Many smart locks, speakers (Xiaomi Mi Smart Speaker) and other techniques support NFC for quick setup, such as attaching a phone to a speaker to connect to it and automatically establishing the connection.

NFC problems on Xiaomi: causes and solutions

If NFC doesn't work or doesn't work, the reasons can be both software and hardware, and let's look at the typical situations and how to fix them.

If none of these things work, check the hardware health of the chip.

1. Install the NFC Check app from Google Play.
2. Run the test - the program will show if the chip is detected.
3. If the test fails, contact the service center (possible antenna break or damage to the module).

💡

On Xiaomi models with MIUI 13+, the “Fast Payments” function appeared – a double press of the power button immediately opens the application for payment (configured in Settings → Special Features → Quick Payments).

NFC Security: How to Protect Data and Avoid Fraudsters

Despite its convenience, NFC can become a vulnerability if precautions are not taken, and fraudsters use special readers to intercept card data from a distance (called skimming), but the risks are minimal if simple rules are followed.

The main threats and methods of protection:

• 🛡️ Unauthorized Reading: Use Covers with RFID-lock-off NFC, when not in use.
• 💳 Cloning cards: don’t store all card details on your phone – add only one basic for everyday payments.
• 📲 Malware tags: Do not bring your phone to unknowns NFC-Labels in public places (may contain harmful links).

MIUI has built-in protection mechanisms:

• 🔒 Blocking when unlocking: payments through NFC Requires unlocking the screen (configured in Settings) → Lock screen → Additionally).
• 📱 Access restriction: in Settings → Annexes → Permits may be prohibited from accessing NFC for unreliable.

💡

To completely disable NFC for payments, remove all cards from Google Pay and reset the module settings (Settings → Connections → NFC → Reset).
