The modern smartphone has long since ceased to be just a means of communication, becoming a universal wallet that is always at hand. Xiaomiβs Redmi Note 8 Pro has become a real hit thanks to its excellent price-performance ratio, including the presence of the NFC (Near Field Communication) module, which allows you to make contactless payments, exchange data and quickly mate with accessories without unnecessary wires.
However, hardware is only half the success, and for the technology to work properly, users need to configure the software and link their bank card, and Android device owners often face the nuances of security and payment service settings, especially in the current market environment.
In this guide, we will discuss in detail the process of activating the module, adding maps to Google Wallet or alternative applications, as well as solving typical errors. NFC-chip on your smartphone model.
β οΈ Note: Before setting up, make sure that your SIM-The card has a mobile Internet service, since a stable connection with the bank server is required for the initial verification of the card in the payment system.
Checking for the presence of NFC module on the device
The first step before any manipulation of payment systems is a reliable confirmation of the presence of the payment system. NFC-Although the Redmi Note 8 Pro originally came with this feature, there are regional versions or firmware modifications where access to the module can be software-limited or hidden.
For quick check, go to the top notification curtain with your finger swiping from top to bottom. In the list of fast switches, find an icon that says NFC. If there is no such icon, click on the menu edit button (usually a pencil icon or a tripod) and check the full list of available widgets. The absence of a module in the list may indicate its disconnection in the system or lack of hardware in this version of the device.
A deeper check is done through system settings. You need to follow the Settings path β Connection and Sharing β NFC. If this menu item is present and the switch is active, then the hardware is functional and ready to go. In some versions of the MIUI shell, the path may be slightly different, for example, located in the Additional Features section.
- π± Check for a badge. NFC fast-paced.
- βοΈ Make sure that the section for managing contactless payments is available in the settings menu.
- π Make sure the battery is above 15%, as when the charge level is low, the system can block the module to save energy.
- π Check if the flight mode is turned on, which forcibly disables all wireless interfaces.
β οΈ Note: If you have reflashed the smartphone on the global version with Chinese, no NFC This may be due to incompatibility of regional configuration files (region lock), which requires flashing the corresponding region.
Preparing a smartphone for secure payments
Financial security is the number one priority for any payment system, and Google Pay (now Google Wallet) and other services require a number of security conditions to be met before allowing the addition of a credit card, first of all, a screen lock must be installed on the device.
Android will not allow you to link the card if you only use a pattern lock or a simple key to unlock it. PIN-code of less than 4 digits, although in the latest versions the requirements may vary.It is recommended to use a strong password, a complex pattern lock or biometric data such as a fingerprint or facial recognition.
Also critical is having a Google account and Google Play services installed, which is why most payment applications are not available without them, and make sure that the date and time on the device are set automatically, as time dissynchronization can lead to an error when checking the bankβs security certificates.
βοΈ Security check before payment
Once the screen lock is set up, the system will issue a warning that card data may be available when the device is unlocked, which is standard procedure to confirm that you are aware of the risks. It is important to understand that payment without unlocking (in sleep mode) on some Xiaomi models may require additional authorization.
Instructions for adding a map to Google Wallet
The process of adding a card to a digital environment is as automated as possible, but requires careful input. Open the Google Wallet app (or Google Pay) on your Redmi Note 8 Pro. If the app is not installed, download it from the official Play Market store.
Click the Add Payment Means button or the + icon. The system will suggest scanning the card with the camera or entering data manually. Camera scanning speeds up the process and minimizes the risk of error in the card number, but in poor lighting, it is better to use manual input.
Way to manually enter: Google Wallet β Add map β Enter data manually β Number, expiration date, CVVOnce you've entered the data, the bank will do the verification, and it can take from a few seconds to a few minutes. SMS-A code or an automatic call with a confirmation code may be sent, in some cases, to the bank to request confirmation of the transaction through its proprietary application.
- π³ Scan the map with a camera to automatically fill in fields.
- π² Wait. SMS-confirmation code messages from the issuing bank.
- β Accept the terms of the agreement with the payment system and the bank.
- π If necessary, confirm your Google account through push notification.
Once successfully linked, the card will appear on the list of available payment methods. By default, it will become the default card, but you can change the priority in the application settings.
Alternative payment systems and Mi Pay
Xiaomi smartphone owners have access to Mi Pay, which is integrated directly into the MIUI shell, a solution that could be a useful alternative, especially if there are problems with Google services or if the terminal does not accept payment through the standard protocol.
To configure Mi Pay, you need to open the application Security or Settings β Mi Pay. Here the procedure is similar to adding a card to Google: you need to scan the card and confirm through the bank. Mi Pay is a feature of the ability to activate the card as the main payment even when the screen is turned off, using a special emulation mode.
Also worth mentioning is the ability to use specific bank applications, where many large financial institutions have their own payment widgets or NFC-enabled apps that can emulate a card regardless of Googleβs system settings, which is relevant in an environment where standard payment systems may be limited.
How does data tokenization work?
Alternative payment methods allow you to always have a working payment tool at hand, and it is recommended to have at least two payment methods configured in case of technical failures in the operation of one of the services.
Setting priorities and operating modes of the NFC
The Android system on the Redmi Note 8 Pro allows you to flexibly customize the behavior of the NFC module. This is especially important if you use your smartphone to read transport cards, electronic passes, or if you have multiple payment applications installed.
In Settings β Connection & Sharing β NFC β Contactless payments, you can choose the default payment app. If you have both Google Wallet and Mi Pay and the bank app installed, this is where you decide which one will run when you bring your phone to the terminal.
Pay-by-confirmation mode is also available here, and if it's enabled, you'll need to unlock the screen or confirm the action with your fingerprint for each transaction, and if it's off, you can pay automatically when you unlock your device, which is faster but less secure if you steal an unlocked phone.
| Setup parameter | Description of function | Recommendation |
|---|---|---|
| Payment application | Selection of the main service for transactions | Google Wallet (standard) |
| Confirmation of payment | Requirement to unlock before payment | Included (for safety) |
| Android Beam | Transfer of files via NFC (outdated) | Off (savings resources) |
| HCE-service | Emulation of cards by the host (for banking applications) | Permitted. |
β οΈ Note: Android Beam has been eliminated in newer versions of Android. If you see this switch, you can safely turn it off, as Nearby Share is now used to transfer files, running over Bluetooth and Wi-Fi.
Solving payment problems on the Redmi Note 8 Pro
Despite the smoothness of the processes, users may experience situations where the terminal is not reading the phone or the payment is not going through, and one of the most common reasons is incompatibility of the case. Too thick protective case, covers with metal elements or magnetic fasteners can shield the signal NFC-antennae.
Another common problem is dirt or damage to the module's location. On the Redmi Note 8 Pro, the antenna is usually located at the top of the back cover, next to the camera. Wipe the area with soft cloth. Also make sure that the phone does not have third-party apps that conflict with system security services.
If the card stopped working after the system update, try removing the card from the application and adding it again. Sometimes the security tokens are updated and the old peg becomes invalid. Also check the status of the card in the bank application - it should not be blocked or have restrictions on online payments.
- π΅ Remove the case and try to make payment again.
- π Reboot your smartphone to restart system services NFC.
- π³ Check in the bank application if the card or limits have expired.
- π‘ Make sure that at the time of payment there is at least a weak signal of the network for online verification.
π‘
Attach the phone to the terminal with the top of the back cover, where the camera is located. In the Note 8 Pro, the antenna module is shifted upwards, and putting the middle of the phone often leads to a read error.
In rare cases, the problem may lie in the payment terminal itself, which does not support modern tokenization protocols. Try paying for a purchase from another store or ask the cashier to pass the card through the chip reader, if the terminal allows the choice of reading method.

In 90% of cases, the payment problem is solved by removing the protective case or re-binding the card in the application after rebooting the smartphone.
