NFC in Xiaomi smartphones: a complete guide to setup and use

Technology NFC (Near Field Communication has long ceased to be exotic – today it is built into almost every Xiaomi smartphone, ranging from budget Redmi to flagship Mi 14 Ultra. But many users still perceive it only as a tool for contactless payments, while the possibilities of the Internet are not. NFC-The module in Xiaomi devices is much wider: from smart home automation to data exchange with one touch.

In this article, we will discuss in detail how exactly it works. NFC Xiaomi at the hardware and software level, what models support the technology (including hidden nuances for different regions), and how to get the most out of it – from setting up Mi Pay to creating automated scripts with Mi Home. Particular attention will be paid to little-known functions that the manufacturer does not advertise, but which can significantly simplify the daily use of the gadget.

If you’ve ever asked questions like “why” NFC Not working after the update MIUI?» Or, "Can I emulate a bank card on Xiaomi?" you'll find not only answers, but also practical solutions with step-by-step instructions. And for older models, we've prepared a current list of devices with support. NFC Explain why some features may be blocked in your area.

What is it? NFC How it works in Xiaomi smartphones

NFC (Near Field Communication (Near Field Communication) is a short-range wireless data transmission technology (up to 10 cm) operating at 13.56 MHz. Unlike Bluetooth or Wi-Fi, it does not require devices to pair and consumes minimal power, making it ideal for instant operations.

In Xiaomi smartphones NFC-The module is integrated into the motherboard and connected to an antenna that is usually located at the top of the body (under the back cover), which allows the device to perform three key functions:

• 💳 Card emulation – the smartphone behaves like a contactless bank card, transport ticket or key card (for example, for the office), used in Mi Pay, Google Pay and other payment systems.
• 📱 Read/write mode – the phone can read data from NFC-tagging (e.g. in stores, museums) or recording information on them (creating automated scripts).
• 🔄 Peer-to-Peer (P2P) — data exchange NFC-devices (for example, sending contacts or photos when touching with spins).

An important nuance for Xiaomi: in some models (for example, Redmi Note 11 Pro)+ 5G) NFC-The module is physically present, but software is disabled for certain regions due to manufacturer restrictions or local laws, which means that even if the specifications indicate that the module is present, it is not available. NFC, The function may not work without manual unlocking (more on this in the section about setting up).

From a security perspective, NFC Xiaomi uses the protocol HCE (Host Card Emulation, which allows you to emulate cards without a physical Secure Element chip, makes integration with banking applications easier, but requires additional protections such as Tokenization (replacing real card data with one-time tokens).

What Xiaomi models support NFC: full list (2026)

Despite the prevalence of technology, NFC It is still not a standard feature for all Xiaomi smartphones.Budget models (e.g. Redmi) A2 or POCO M6) The main devices are often devoid of modules, while flagships (Xiaomi 14, Mix Fold 3) receive support by default. NFC, series-series.

⚠️ Note: Even if your model is on the list, check regional firmware. e.g. Redmi Note 11 Pro+ 5G China has NFC, A version for India (Redmi Note 11 Pro)+ 5G India) - no. To get the exact configuration, type the command in the engineering menu:

##4636##

Then go to Phone Information. → NFC. If there is no partition, the module is not physically present.

For models with software disabled NFC (for example, POCO X3 Pro for some markets, you can try unlocking the function through ADB:

adb shell settings put global nfc_enabled 1

However, this can lead to unstable operation or blocking of Mi Pay.

💡

Before buying a smartphone Xiaomi with NFC Check not only the model, but also the region of sale.+ 5G Europe has NFC, The Latin American version is not, and this information is usually shown in the full model name (e.g., the model name, 22101316G — global).
