How to run NFC on Xiaomi: full instructions with pictures and tips

NFC (Near Field Communication) technology has become an integral part of modern smartphones, allowing contactless payments, data exchange and connection to smart devices with a single touch. Owners of Xiaomi phones (including sub-brands Redmi and POCO) often face the question: how to properly activate and configure this module? Despite the apparent simplicity, the process is nuanced depending on the device model and version of MIUI.

In this article, we will discuss not only the basic steps to include NFC, But we also look at common problems (for example, when the function is gray or not on the menu), as well as advanced use cases - from linking bank cards to automating tasks through Xiaomi Home. NXP (Xiaomi 13 Pro or Redmi Note 12 Pro+), where technology support is implemented at the hardware level.

Compatibility Check: Is there NFC in your Xiaomi?

Configure contactless payments via NFC

One of the most popular NFC scenarios is smartphone payments, which would require linking a bank card to one of the supported services.

Supported services on Xiaomi:

💳 Google Pay (works on all models with Google Pay) NFC and certified firmware).
💳 Mi Pay (available in China, Russia and some CIS countries; requires registration with Mi Account).
💳 Samsung Pay (only on models with Samsung Pay Mini chip, for example, Xiaomi Mi 11 Ultra for the Korean market).

Instructions for Google Pay:

Download the Google Pay app from the Play Market.
Open it and press Start.

If the terminal is not reading the card when paying, try holding the phone to the top of the terminal (where the NFC antenna is usually located). Also make sure the device screen is on - on some models, payments do not work when turned off.

NFC problems on Xiaomi: causes and solutions

Even if your device supports NFC, you may encounter errors when using it. Let's look at typical situations and how to fix them.

Problem.	Possible cause	Decision
NFC gray in the settings	No hardware support or a module at the firmware level is disabled	Check the model specifications or reflash the device to the global version of MIUI
Payment's not working.	Not configured by default or blocked by the bank	Select the payment service in the NFC settings and contact the bank
The device doesn't read tags.	Weak antenna signal or interference from cover	Remove the case and bring the phone closer to the mark (at a distance of 1-2 cm)
NFC is spontaneously shut down	Battery Optimization Disables Module in the Background	Add an NFC app to optimisation exclusions (Settings → Battery → Battery Optimisation)

If none of these methods worked, try resetting your network settings:

Settings → System → Resetting → Resetting Wi-Fi, mobile network and Bluetooth

⚠️ Note: Some custom firmware (e.g. LineageOS or Pixel Experience) NFC It may not work properly due to lack of proprietary drivers NXP. In this case, it is recommended to return to the official MIUI.

Expanded NFC capabilities on Xiaomi

In addition to payments, NFC on Xiaomi can be used to automate tasks, manage smart devices, and even create custom scripts.

Examples of advanced applications:

🏠 Smart home: Set up NFC-Labels to turn on lights, start a robot vacuum cleaner or activate the “Home” mode through Xiaomi Home.
📱 Automation: With the Tasker or MacroDroid app, create rules, for example: When touching a label on your desktop, turn on silent mode and launch Telegram".
🔑 Electronic keys: Some hotels and offices use NFC For access, your Xiaomi can replace a plastic card.
🎮 Gaming controllers: Connect wireless gamepads (e.g, 8BitDo) through NFC fast-sync.

To work with labels will require:

Buy NFC-tags (e.g, NTAG213/215/216 AliExpress).
Install the recording app: NFC Tools, Trigger or Mi Tag (for devices with MIUI).
Write a command (such as a URL, text, or task for Xiaomi Home) on the tag.

How to write down a label for automation?

1. Open the NFC Tools app. 2. Select "Write" → "Add Record." 3. Specify the data type (e.g., "Start App" or "Text"). 4. Hold the phone to a clean label and wait for the recording confirmation. 5. Attach the tag to a convenient location (e.g., refrigerator door or bedside table).

Comparison of NFC in different Xiaomi models

Not all Xiaomi smartphones work equally well with NFC. The difference is the type of chip, protocol support, and data rate. Below is a comparison table for popular models.

Model	Type of NFC chip	Support for payments	Additional functions
Xiaomi 13 Ultra	NXP PN80T	Google Pay, Mi Pay, Samsung Pay (in some regions)	UWB support for accurate tag positioning
Redmi Note 12 Pro+	NXP PN54T	Google Pay, Mi Pay	Fast file transfer via Android Beam
POCO F5 Pro	NXP SN100T	Google Pay	Optimized for gaming controllers
Xiaomi 12T	NXP PN81A	Google Pay, Mi Pay (with restrictions)	Support for virtual keys for cars (in test mode)

Models with NXP chips (such as the Xiaomi 13 Pro or Redmi K60) typically show better stability and speed than devices with Broadcom or Qualcomm chips.

💡

If you want maximum NFC functionality (such as for smart homes or automation), choose models with NXP chips – they support more protocols and are more stable.
