NFC in Xiaomi: what is this module, how it works and why you need a smartphone

If you’ve ever wondered how your Xiaomi smartphone can instantly pay for purchases, unlock doors, or share data with other devices with a single touch, the answer lies in a small but powerful module called NFC. This technology, once the preserve of flagship models, is found even in the brand’s budget smartphones today. But what exactly lies behind the acronym NFC, how this module is integrated into the Xiaomi ecosystem, and why its presence can be a decisive factor in choosing a new gadget?

In this article, we’ll not only explore the technical side of the issue, but also show you practical examples of NFC use, from contactless payments to smart home management, which Xiaomi models are equipped with this module, how to activate it, and what hidden features it offers beyond standard options, and we’ll also dispel myths about NFC security and explain why this technology remains relevant even with the advent of more modern alternatives.

What is NFC and how does it work in Xiaomi smartphones

NFC (Near Field Communication) is a short-range wireless communication technology (up to 10 cm) that allows devices to communicate or initiate actions by simply touching or close-to-be. Unlike Bluetooth or Wi-Fi, NFC does not require complex pairing configuration and works almost instantly.

In Xiaomi smartphones, the NFC module is usually a separate chip integrated into the motherboard.It operates at 13.56 MHz and supports three main modes:

• 📱 Active mode – both devices generate their own electromagnetic field (for example, when transferring files between two smartphones).
• 💳 Passive mode – one device (for example, a payment terminal) creates a field, and the smartphone responds (contactless payments).
• 🔄 Card emulation mode – the smartphone simulates a contactless card (for example, for passage in the subway).

The peculiarity of the implementation of NFC in Xiaomi is deep integration with the proprietary shell MIUI. For example, in models with MIUI 12+, the function “Fast NFC Actions” appeared, allowing you to run applications or scenarios of a smart home with one touch to the label.

Xiaomi models support NFC: full list for 2026

While NFC was a flagship 5 years ago, it is now found even in Xiaomi’s budget lineups, not all models are equipped with this module, especially for devices in emerging markets where the technology is not yet in demand. Below is an up-to-date table of Xiaomi, Redmi and POCO smartphones that support NFC, showing the year of release and regional availability.

It's important to note that even within a single model, there can be regional differences, such as the Redmi Note 12 Pro in China, which is often devoid of the same name. NFC, While the global version is equipped with a module, before buying, be sure to check the specifications on the official Xiaomi website or in the certification databases (for example, before buying, FCC or TENAA).

⚠️ Note: Some sellers may indicate NFC In the specifications, although the module is not actually available, to avoid being tricked, ask for a photo of the sticker under the battery on the original devices with the battery. NFC there will be appropriate markings.

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

NFC activation on Xiaomi smartphones takes less than a minute, but many users are unaware of the hidden capabilities of this module.

1. Enable the module: Go to Settings → Connections and Sharing → NFC and activate the switch. In some models (for example, Xiaomi 13), the path may be different: Settings → Additional → Wireless Networks → NFC.
2. Contactless payments: For Google Pay or MI Pay, you need to add a bank card in the application and confirm it via SMS. In MIUI 14, the option “Fast Payment Access” has appeared – double pressing the power button calls the wallet.
3. Using NFC tags: In the NFC menu, activate the "Read tags" option. Now you can program chips to run scripts (for example, turning on Wi-Fi when touching the tag on your desktop).

Check the presence of the module in the characteristics of the model

Update MIUI to the latest version

Add a bank card to Google Pay/MI Pay

Activate the "Read tags" option in the NFC settings

Make sure the battery is charged (for stable payment operation)

-->

Advanced users can have additional settings through Developer Mode, such as changing the data exchange protocol (NDEF is the default), or turning off the sound signals when NFC is triggered. However, it is not recommended to touch these settings without having to, as incorrect settings can cause the module to malfunction.

💡

If NFC suddenly stopped working, try calibrating the module: go to Settings → About Phone → Diagnostics → Equipment Test → NFC and follow the instructions on the screen.

Practical ways to use NFC in Xiaomi: from payments to smart home

Many people mistakenly believe that NFC in a smartphone is only for contactless payments, but in fact, the range of applications of this technology is much wider. Here are 7 non-obvious ways to use the module in Xiaomi devices:

• 🚗 Digital keys for cars: Modern cars (e.g, BMW Hyundai supports unlocking through NFC. Xiaomi. 13T Pro this function works with the Digital Key application.
• 🏠 Smart home management: Tags NFC You can program to turn on the lights, start a robot vacuum cleaner or activate the “Home” mode in Mi Home.
• 🎮 Connecting game controllers: Some gamepads (e.g, 8BitDo) They are connected to the smartphone through NFC fast-sync.
• 📁 Instant File Transfer: Fast Share (formerly Mi Share) allows you to send photos or documents between Xiaomi devices with one touch.
• 🚇 In Moscow, Beijing and other cities, you can use a smartphone instead of a transport card (for example, Troika or Octopus).
• 🔑 Electronic passes: Some offices and university campuses issue virtual passes that are read through NFC.
• 🎫 Tickets and coupons: Airfare, discount cards or movie tickets can be saved to Google Wallet and presented via Google Wallet NFC.

One of the most interesting scenarios is using programmable NFC tags, for example, you can buy a set of chips for 200-300 rubles and configure them to:

• 🔊 Automatic Bluetooth activation in the car when touching the tag on the phone holder.
• 📵 Going to "Do Not Disturb" mode when touching the mark on the bedside table.
• 🌐 Quick Wi-Fi connection to guests (tag contains network data).

Automate application or built-in tools can be used to automate processes. MIUI. For example, in Xiaomi 14 appeared feature "NFC-triggers, which allows you to create chains of action when the label is triggered.

NFC Security: Myths and Real Risks

One of the most common fears of users is that NFC can be hacked and attackers will charge money from a card or steal data, and the technology is actually built with multiple protections in mind, but there are nuances to be aware of.

First, the triggering distance. NFC It's only 5 to 10 cm, making remote reading almost impossible (PIN-code, fingerprint or face ID). However, there are real risks:

• 💰 Skimming: Scammers can set up a reader on an ATM or terminal to intercept card data, but this is true for physical cards, virtual cards in Google Pay or a virtual card in Google Pay. MI Pay generates one-time tokens that are useless for attackers.
• 📱 Switching tags: If you are using NFC-Labels for automation, theoretically, can be replaced with other ones with malicious code. Always buy tags from trusted vendors.
• 🔄 Intermediate attacks: In theory, it is possible to intercept a signal between two devices, but this requires specialized equipment and physical access.

⚠️ Warning: Never store on NFC-passwords or personal information in plain form. Use encryption for sensitive data (e.g., through the Cryptomator app).

To minimize the risks:

• Turn off NFC when not in use (although this is not necessary – the module is passive without active actions).
• Use only official payment applications (Google Pay, MI Pay, banking applications).
• Set up payment notifications in the banking application.
• Do not bring your phone to unknown persons. NFC-terminals (for example, in public places).

V MIUI 14, the "Protection" function appears NFC", It's a system that blocks unauthorized reading. To activate it, go to Settings. → Confidentiality → Protection NFC and turn on "Unlock required." Now for anyone. NFC-The interaction will require a fingerprint confirmation or PIN-code.

Frequent NFC Issues on Xiaomi and How to Fix Them

NFC — It's a reliable technology, and sometimes users have problems.-5 problems and ways of solving them:

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

1. Go to Settings → System → Resetting of settings → Resetting of network settings.
2. Confirm the action (this won’t delete your data, but will reset all network settings).
3. Restart your phone and check the NFC.

In rare cases, the problem can be hardware, such as damage to the NFC antenna. This is true for phones that often dropped or repaired. If the resetting did not help, contact the Xiaomi service center for diagnosis. The cost of replacing the NFC module usually does not exceed 1,500-2,500 rubles.

💡

If NFC stopped working after the MIUI update, try rolling back on the previous firmware version or wait for a patch. Often bugs are fixed in the next updates.

NFC vs UWB vs Bluetooth: What’s Better and Why Xiaomi Chooses NFC

With the advent of new wireless technologies (such as UWB or Bluetooth LE Audio), many people are wondering whether NFC is outdated.

Why Xiaomi continues to use NFC despite the advent of UWB?

• 💳 Compatibility: NFC It is supported by billions of devices around the world, from ATMs to turnstiles.
• 🔋 Energy efficiency: Module NFC It consumes 10 times less energy than Bluetooth or UWB.
• 🛒 Infrastructure: Contactless payments through NFC They are available in 99% of stores, but UWB It is currently only used in premium devices.
• 🔒 Safety: Short work distance NFC It is less vulnerable to attack than Bluetooth.

However, in flagship models (such as the Xiaomi 14 Ultra), NFC coexists with UWB. The latter is used for precise spatial positioning (for example, to point the camera at an object or unlock the car from a distance of several meters), whereas NFC remains for payments and interaction with tags.

NFC is unlikely to disappear in the next 5 years, as banks, transportation systems and smart tech manufacturers continue to support it, and with hybrid solutions (NFC + UWB), Xiaomi smartphones get the best of both worlds.
