How to connect and configure NFC on a Xiaomi smartphone

Xiaomi, Redmi and POCO are no longer just phone devices, becoming full-fledged digital wallets and tools for fast data transfer. NFC technology, which allows you to exchange information over ultra-small distances, plays a key role in this process. For many users, turning this feature into a first step towards eliminating plastic cards and simplifying everyday life.

However, despite the ubiquity of the technology, device owners often have difficulty activating or using it, which can be due to both the software limitations of the MIUI or HyperOS operating system and the banal misunderstanding of the location of switches. In this article, we will discuss in detail how to properly activate the module, set up secure payment, and what to do if standard methods do not work.

Before you get to the settings, make sure your device is technically equipped with the necessary module. Not all budget models support this feature, and the absence of an on button does not always mean an error in the system. In devices with entry-level Snapdragon processors, the NFC module may be physically absent, making it impossible to program activate it.

Checking for the presence of an NFC module in the device

The first and most important step is to verify the hardware support of the technology, and users often try to activate a feature that is not provided by the manufacturer in a particular smartphone model, and the most reliable way to verify it is to look at the official specifications on the manufacturer's website or in the documentation attached to the box.

You can also use the system's built-in tools for quick diagnosis, which will take just a few seconds and avoid unnecessary manipulation of the settings if the module is missing.

• 📱 Open the standard Phone app and dial the combination ##6484## to log into the engineering menu.
• 🔍 In the test list, find a point. NFC Test or just NFC.
• ✅ If such a point is present and when you press the test is started, the module is installed and serviceable.
• ❌ The absence of a menu item or an error message indicates the absence of a chip.

An alternative way is to install specialized applications from the Google Play store, such as NFC Check or Ampere, which read information about the hardware of the smartphone and accurately report the presence or absence of the corresponding controller.

⚠️ Note: If the engineering menu does not open by code, it does not always mean that there is no code. NFC. On some global firmware, access to hidden menus may be restricted.

For a deeper check, you can use the command via ADB if you have a computer connected, which is a professional method that gives you a 100% guarantee of results.

adb shell pm list features | grep nfc

If the answer appears android.hardware.nfc, then the software is in place, and the problem lies solely in the software settings.

Standard activation through system settings

In most cases, to enable the technology, it is enough to perform a standard sequence of actions in the smartphone menu. The interface of the Xiaomi shells may differ slightly depending on the version of Android and regional firmware, but the logic remains the same.

You need to go to the main settings menu, which is usually indicated by a gear, and then the path can go through the section “Connect and share” or “Additional features”.

• 🔌 Go to Connection and Sharing (Connection & Sharing).
• 📡 Find a point in the list NFC and move the switch to the active position.
• 💳 Immediately after inclusion, it is recommended to click on the text of the paragraph itself to open the advanced settings.
• 🔒 Make sure that the Secure Element function is activated if it is available.

On some versions of MIUI, the switch may be in the "More" menu inside the wireless network settings. If you don't find a item, search for the settings by typing the word "NFC" into the search bar at the top.

It is important to understand that simply turning on the toggler does not guarantee the operation of contactless payment.

Setting up payment applications and Google Pay

Once activated, the module is set up to pay, and in the Android ecosystem, Google Pay (or its analogues, such as Mir Pay depending on the region and availability of Google services) is central to the tokenization of your cards.

It is critical to install the correct default application for transactions, and if the system selects the wrong application, the payment terminal may not respond to the presentation of the smartphone.

In the advanced NFC settings, look for touch and pay or no contact payment, and you will see a list of all the apps you have installed that can handle payment tokens, and you can select the one you want (like Google Pay) and confirm your choice.

Remember to add a card to the app. The verification process usually takes a few minutes and requires you to enter the code from SMS. Once the card is successfully linked, the phone is ready to purchase.

💡

To improve payment security, always install a complex password or biometric security (fingerprint/face) on your smartphone lock screen.

Use of labels and transfer of data

The technology’s functionality is not limited to financial transactions; Xiaomi smartphones allow users to use the technology. NFC-Labels for automating actions and quickly transferring files between devices, which is especially convenient for creating a smart home or quickly pairing with accessories.

Data transfer is carried out through the standard Android Beam protocol (on older versions) or through native exchange via NFC.

And then there are apps that record your own labels, and you can program the tag so that when you touch it, the phone does things like turn on Wi-Fi, start the navigator, or set an alarm.

• 🏷️ Install an application to record labels, for example, NFC Tools.
• 📝 Select the action that the smartphone should perform (launching the application, opening the site).
• 💾 Click "Write" and bring an empty tag to the back of the phone.
• ✅ After recording, the tag is ready to be used anywhere.

These tags can be placed in the car to automatically turn on Bluetooth music or on the desktop for a quick transition to Do Not Disturb mode.

⚠️ WARNING: When writing tags, make sure you don’t overwrite important system data if you use someone else’s or corporate tags.

The Solution: Why the NFC Doesn't Work

Even with the right settings, users may encounter a situation where the terminal is not reading the phone or the function is unstable, most often the problem lies in a protective case or software conflict.

Thick cases, especially those containing metal plates or magnets for attachment in the car, shield the signal. The NFC antenna is located at the top of the rear cover, and any obstacle in this area is critical.

It’s also worth checking if the power saving mode is on: In an attempt to keep the battery powered, the system can limit the background activity of the communication module, leading to payment disruptions.

Settings → Battery → Power saving mode (Switch off)

If a software failure persists, resetting your network settings will help, which will not delete your personal photos or contacts, but will return your Bluetooth, Wi-Fi and mobile network settings to factory values.
