One of the key features that ensures comfort is the NFC module (Near Field Communication), which allows you to exchange data over short distances. Owners of Xiaomi, Redmi and Poco devices often wonder how to activate this module and what opportunities it opens for them.

The short-range contactless technology works at 13.56 MHz and provides instant connection between devices without complex pairing settings. Just bring the gadget to the reader or other phone up to 10 centimeters. In the MIUI ecosystem, management of this module is implemented as simple as possible, but for full operation requires the correct primary configuration.

Where and how to enable NFC on Xiaomi

The first step to using contactless is to check if the appropriate module is in your device. Not all budget models are equipped with a communication chip, so it is worth checking its presence through the system settings. To do this, go to the Settings menu and search for a keyword or look for the Connection and Sharing section.

If the module is present, you will see an NFC switch that can be turned off by default. Activation takes one second: just put the slider in the active position. In some versions of the MIUI shell, access to this feature is duplicated in the notification curtain, which allows you to quickly turn the module on and off as needed.

Importantly, once enabled, the system can request a default payment application, which is critical because it depends on which service will be launched when you bring your phone to the terminal. If you plan to use banking applications or third-party wallets, make sure you choose the software you need.

• 📍 Open Settings and go to Connection and Sharing.
• 🔘 Find a point. NFC and activate the switch.
• 📱 Add the icon to the curtain for quick access via the editing menu.
• ⚙️ Select the default application for making payments.

⚠️ Warning: If you can't see the switch NFC In the menus, you may not have this module on your smartphone. Check the specifications on the manufacturer's official website.

Once the module is activated, it is recommended to check its performance immediately, to try to read the balance of the transport card or simply hold the phone to another device with the function on, the system should emit a characteristic sound or vibrate, confirming the successful detection of the tag.

Keep in mind that the module’s constant standby mode has minimal effects on battery power, but for maximum energy savings, it’s best to turn it off if you don’t plan to use it during the day, especially for devices with less than the most capacious battery.

Setting up contactless payment on Android

Using a smartphone to pay for purchases is one of the most popular features of NFC. Xiaomi owners can link bank cards to services like Google Pay (depending on the region) or use applications of specific banks. The setup process requires care, because the security of your funds.

There is an important parameter in MIUI settings that affects transaction security: Security and privacy menu -> Security element can check the certification status of the device. If the phone has been modified (root rights obtained), payment systems can block transactions.

⚠️ Warning: Never attempt to make a payment with an unlocked phone in a public place unattended.Use biometric security or pin to confirm each transaction.

When you pay in the store, just unlock the screen and hold the top of the back of your smartphone to the terminal. You don't have to open the bank app, the system recognizes the terminal itself and conducts the operation through the default application. Successful payment will be confirmed by vibration and sound.

• 💳 Open the application of the bank or payment system.
• 📸 Scan the map or enter the data manually.
• 🔐 Confirm the binding with the code from SMS.
• 🛒 Bring your phone to the terminal for payment.

It is worth mentioning that in some regions direct payment via Google Pay may be limited. QR-codes through bank applications, but the technology NFC remains relevant for travel in transport and work with electronic passes.

Use of Mi Pay and alternative services

Xiaomi has developed its own Mi Pay service, which allows you to add cards from different banks for contactless payment. Although the functionality of the service can vary depending on the country, the principle of operation remains the same for all devices of the brand.

To set up Mi Pay, you need to log into your Mi Account. After logging in to the Mi Pay app or through your system settings, select the option to add a card. The system will automatically determine the bank and offer the appropriate terms of service.

The advantage of using Xiaomi native solutions is deep integration with the MIUI shell.This provides more stable work in the background and less power consumption compared to third-party applications.In addition, Mi Pay often supports features not available in standard Android.

Alternative services like Samsung Pay (on some models) or transport card apps can also be used, and the key is to choose the right default app in the NFC settings so that when you reach the reader, you run exactly the software you need at the moment.

• 🔑 Sign in to your Mi Account.
• ➕ Click on “Add Card” in the Mi Pay app.
• ✅ Accept the terms of the agreement and confirm the data.
• 📲 Use your phone to pay at terminals.

Transfer of files and data via Android Beam

In addition to payment, the NFC module is used to quickly transfer files between devices. Android Beam technology (or its modern counterparts) allows you to transfer contacts, links, photos and small video files with a simple touch of phones, which is much faster and more convenient than finding a device in Bluetooth.

To transfer data, make sure that NFC is enabled on both devices. Unlock screens and open the content you want to transfer (such as a photo in a gallery or a website in a browser). Hold the backs of your smartphones against each other before the characteristic sound or vibration appears.

The system will suggest that you confirm the transfer of the file. Once confirmed, you will start copying the data. The transfer speed depends on the file size and the version of Android, but for small amounts of information, this method is one of the fastest.

⚠️ Warning: Do not interrupt the connection during file transfer. Devices disconnected before the process is complete may cause file corruption or transfer error.

It’s worth noting that newer versions of Android have eliminated the Android Beam feature in favor of Nearby Share, which uses a combination of Bluetooth and Wi-Fi Direct to transmit, but is initiated over NFC.

When using this feature, keep in mind privacy.Do not accept files from unknown devices, as this could theoretically be used to transmit malware, although Xiaomi's current security systems effectively block such attempts.

Work with transport maps and passes

One of the most useful features of NFC on Xiaomi is emulating transport cards and passes, so you can add a subway card, a bus card, or an office key directly to your phone, eliminating the need to carry plastic cards and keys.

To add a transport card, open the Wallet app or a specialized app in your city, select the type of card, top up the balance, and follow the activation instructions, and then, when you bring the phone to the turnstile, it will work like a regular plastic card.

In the case of electronic passes (intercoms, office cards), the situation is more complicated. Many systems use standard protocols that Xiaomi knows how to emulate. However, some proprietary systems may not be supported. To check the existing card, hold it to the back of the phone: if the system offers to copy the data, you are lucky.

It's important to understand the difference between reading a card and emulating it. A phone can read the balance of a card, but it can't emulate it if the card chip uses a secure protocol that's not supported by a smartphone, and you have to use stickers or key fobs.

• 🚌 Open the Wallet app or transport app.
• 🆔 Select the option "Add a transport card».
• 💰 Replenish the balance and activate the card.
• 🚇 Put your phone on the turnstile to pay.
