How to use NFC on Xiaomi Redmi Note 8 Pro: Full Guide

Owners of the Xiaomi Redmi Note 8 Pro often wonder how to make the most of the built-in short-range contactless module. This compact chip hidden in the device’s case provides access to a wide range of features, from quick one-touch payment to instant data transfer between gadgets. Although the interface of the MIUI operating system may seem overloaded, the management of wireless protocols here is implemented logically and affordable.

However, many users are struggling to initial activate or are unaware of hidden features that make everyday smartphone usage much easier. NFC (Near Field Communication) operates at 13.56 MHz and provides a reliable connection at up to 10 centimeters, which guarantees the security of your transactions. In this article, we will take a look at all the nuances of the module, from basic activation to fine-tuning for payment systems.

Understanding how this module works will allow you to not only pay for in-store purchases, but also automate routine tasks, as well as quickly exchange contacts and links. In the Xiaomi Redmi Note 8 Pro, the NFC antenna is located at the top of the case, next to the main camera. Knowing the exact location of the antenna is critical for successful card and tag reading, since shifting the phone even a couple of centimeters can lead to a connection error.

Activation and check of the module operability

The first step before you start using any wireless technology is to activate it correctly in your system settings. In the MIUI shell, the NFC switching process is as simple as possible and takes only a few seconds, and you don't have to search for complex engineering menus or enter special codes, since all the necessary switches are displayed in a prominent place.

There are two main ways to activate the module: the first option is to use the notification curtain, which is the fastest method; the second option involves diving into a deep settings menu where you can find additional options if they are available in your version of the firmware, the choice of method depends on the personal preferences and habits of the user.

Once the module is enabled, the system may request confirmation or offer to configure additional services such as Google Pay or Mi Pay if they are supported in your area. Ignore these offers as they help prepare the smartphone for secure transactions. If the icon in the curtain is active after turning on, but the terminals do not respond, it may be a case or software failure.

⚠️ Warning: Some protective covers with metal inserts or magnetic fasteners may shield the signal by making use of the NFC If you notice a reading problem, try to remove the cover.

Configure contactless payment via Google Pay

One of the main features for which users activate this module is the ability to pay for purchases with a smartphone. To implement this feature, the Xiaomi Redmi Note 8 Pro uses Google Pay (or its current analogue Google Wallet).

The process of linking a credit card requires care and physical media or access to Internet banking. The app automatically reads data through the camera or allows you to enter it manually, then sends a request to the bank for verification. Tokenization of data ensures that the real number of your card is not transferred to the seller, which increases the level of security.

• 📱 Install and update the Google Pay app to the latest version through the official Play Market Store.
• 💳 Click the Add Card button and select the way you enter data: Camera scan or manual input.
• 🔐 Go through the confirmation procedure via SMS code or call to the bank as required by financial security regulations.
• ⚙️ Install Google Pay as the default primary payment method in your settings NFC.

It's important to note that the smartphone screen needs to be unlocked to operate the payment system, but you don't need to run the app itself. You just have to bring the device to the terminal, and the system will determine the priority payment method, and if there are several cards, you can quickly switch between them before paying.

Use of Mi Pay and Alternative Payment Systems

Xiaomi device owners have access to Mi Pay, which in some regions and banks can work more stable or offer unique bonuses. Its working principle is similar to Google’s, but the integration with the MIUI shell is deeper, which allows you to access the feature even with the screen off in certain scenarios.

To set up Mi Pay, you need to log in to your Mi Account and add a card through the corresponding “Mi Credit Card” app or through NFC settings. The system supports major payment systems, however, the list of supported banks may differ from the list for Google Pay.

Payment via Mi Pay often requires additional biometric authentication, which adds another layer of protection to your finances.The smartphone will request a fingerprint or facial recognition directly at the time of accessing the terminal if the transaction amount exceeds a certain limit or if it is required by bank policy.

The choice between different payment systems is often dictated by the specific bank stocks or the technical features of the terminals in your favorite stores, and it is recommended to test both options to see which one works faster and more stable in your city.

File transfer and contact exchange

In addition to payment, the NFC module on the Xiaomi Redmi Note 8 Pro is great at transferring small amounts of data, such as contacts, links to sites or geolocation coordinates. This method is much faster and more convenient than manually entering information or finding a device in the Bluetooth list. NFC is used only for pairing to transfer large files (photos, videos), after which the communication channel switches to faster Wi-Fi Direct or Bluetooth.

To pass the contact, you just need to open the card of the desired subscriber in the phone book and bring your phone to the phone of the interlocutor. Provided that both devices are on the module and unlocked the screen, the system will prompt you to receive or send data, a process called Android Beam (or its modern counterparts in new versions of Android).

• 📲 Make sure that both smartphones have a feature enabled. NFC Bluetooth.
• 🔓 Unlock the screens of both devices and hold them back to each other.
• 📤 Tap the screen when the request for transmission appears, or just wait for the confirmation vibration.
• 📥 Only accept files from trusted sources to avoid malware infection.

This feature is especially useful when sharing Wi-Fi passwords, and if a guest comes to your house, you don't have to dictate a complicated password, just bring his phone to your phone (if he's already connected to the network), and the network settings will be automatically transmitted to his device, which is implemented natively in the Android ecosystem and works without installing additional applications.

Work with NFC-tagging and task automation

The module’s capabilities are not limited to communicating with other phones or payment terminals. Xiaomi Redmi Note 8 Pro can read special devices. NFC-Labels, which are tiny chips programmed to do certain things, open up huge possibilities for automating everyday tasks and creating smart environments.

To work with tags, you need a special application, such as NFC Tools or Trigger, which you can use to write a label to start an application, turn on the alarm, change the sound settings, or even open a navigator with a laid route to work. The tags are inexpensive and can be placed in the car, by the bed or on the desktop.

The process of writing the label is simple and intuitive: you select an action in the app, you click on the Write button, and you bring the phone to the clean label, and once you successfully write it down, it's ready to use, and now every time you touch that zone, your smartphone will execute that algorithm instantly.

⚠️ Warning: When writing data to a label, make sure it is not password protected from recording if you plan to change information in the future (NTAG213) You cannot overwrite after the first use.

Diagnostics and troubleshooting

Despite the reliability of the technology, users of Xiaomi Redmi Note 8 Pro can face situations when NFC stops working correctly, most often problems are software-related or related to physical obstacles, understanding the causes of the malfunction will help quickly return functionality without going to the service center.

If the phone has stopped seeing cards or terminals, the first thing to do is check if there have been recent system updates that could have knocked the settings, and make sure the settings have the correct default payment app, sometimes by simply restarting the device, which resets temporary errors in the radio module.

In cases where software methods do not help, it is worth considering the possibility of physical damage to the antenna. Falling a smartphone, especially in the area of the main camera, could damage the plume or the module itself.
