The modern smartphone has long since ceased to be just a phone, becoming a universal tool for financial management. Xiaomi Redmi 8 Pro owners often wonder how to activate contactless payment feature so as not to carry a wallet. This model, released in 2019, is equipped with the necessary NFC module, which theoretically allows you to make purchases with a single touch.
However, the setup process can seem confusing due to the features of the MIUI shell and the current situation with payment systems. You will not only need to turn on the appropriate switch, but also to adjust the security correctly, and choose the appropriate emulator application. In this article, we will discuss each step in detail so that you can use the comfort technologies.
It should be noted that the standard Google Pay service on Xiaomi devices with Russian bank cards does not work now. Therefore, we will focus on alternative methods, such as Mir Pay or third-party solutions that allow you to emulate bank cards.
Verification of availability and activation of the NFC module
Before you go to installing apps, make sure the hardware of your Redmi 8 Pro is ready to go.The Near Field Communication module is built into the top of the smartphone body, next to the main camera.
Go to Settings, then select Connect and Sharing, and here you will find an NFC switch that can be turned off by default, and then move it to the active position, and then the system will prompt you to select the default payment application.
⚠️ Attention: If, after activation, NFC The smartphone starts to heat up quickly in the camera area, check the running background processes. Constant search for tags can consume battery power, so it is recommended to turn on the function only before going to the store.
It is also important to check whether the module is blocked by a carrier or by regional firmware restrictions. In some versions of MIUI for the global market (Global ROM), the functionality may differ from the Chinese versions.
Once activated, the notification curtain will show an icon in the notification curtain, and if it's not there, try rebooting the device, which is a standard procedure that helps the system to properly initialize hardware drivers.
Installation and configuration of payment applications
The main tool for owners of maps on Android today is the Mir Pay app. It is available in the AppGallery store or through direct download. APK-The installation is done in a standard way, but requires permission to install from unknown sources if you are downloading the file from a non-built-in marketplace.
Once you start the app, you'll need to sign up, the system will request a phone number, and create a secure profile, and that's where your credit card is linked to a digital token, and the encryption process takes place on the bank server side, which guarantees the security of transactions.
For users of other banking products, there are similar solutions, such as SberPay or specific bank applications that support tokenization, which are the same: you scan the card with a camera or enter data manually, after which the bank sends a confirmation code via SMS or push notification.
Remember that these applications require NFC and camera permissions to work, and MIUI will request permissions to be validated when it first starts, without which Redmi 8 Pro will not be able to read card data or transmit a signal to the terminal.
Adding a bank card to the system
The process of adding a card to Mir Pay or a similar service requires care. Open the app and click the add a new card button. You will be prompted to scan the front side of the plastic through the camera or enter the number, expiration date and CVV code manually.
The camera is preferable because it minimizes the risk of error when entering long digital sequences. After scanning, the system will ask you to confirm the data. If the card is issued by a bank that supports tokenization, you will receive a card that will be sent to the user. SMS-verification.
| Parameter | Description | Where to find out. |
|---|---|---|
| Card number | 16-digit code | The front |
| Duration of validity | Format MM/GY | The front |
| CVV/CVC code | 3 numbers | The flip side |
| Name of owner | Latino | The front |
Once successfully linked, the card will appear on the list of available payment options, you can assign it to the primary account, so that when you unlock the phone and bring it to the terminal, this account is used, and you can also set limits or require biometric authorization for each purchase in the application settings.
If a bank does not support direct in-app tokenization, you may need to issue a virtual card, a temporary number that is generated in a banking application and added to a payment service, a method often used to increase cybersecurity when shopping online.
Security and biometrics setting
Payment data security on Xiaomi Redmi 8 Pro is provided with several layers of protection. The first level is the screen lock. The system will not allow payment if the phone is locked or not authorized. PIN-code.
The second level is biometrics. The smartphone has a fingerprint scanner built into the power button on the side of the face. To set up, go to Settings → Passwords and Security → Fingerprints. Add a fingerprint that will be used to confirm transactions.
☑️ Security setting
Also worth paying attention to is Google Play Protect, which automatically checks installed apps for malicious code, and make sure that this feature is active in the Play Market store settings, which will prevent the installation of fake versions of payment applications that can steal card data.
⚠️ Warning: Never install modified versions of payment applications (mods) from unverified sources, which may result in a bank blocking or financial data leakage.
In some cases, payment services require security certificates in the system. If an application reports a security error, check if a root right has been created on the device.
Solving Payment Issues
It's not uncommon for users to see a terminal, but the payment doesn't go through. One of the common causes is that the smartphone is in the wrong position. The NFC module in Redmi 8 Pro is at the top. Put the phone at that angle to the readout area of the terminal.
Another common problem is a thick case, and if you use a case with a metal insert or a magnetic clasp, it can shield the signal, try to remove the case and try again, and the signal can jam the accumulated cards in the case.
What if the terminal can’t see the phone?
If the problem is a software failure, try clearing the cache of the Mir Pay app or service you use. Go to Settings → Apps → All apps, find the right one and select Clear the cache. This will not delete your cards, but will reset temporary files that may have been corrupted.
In case nothing works, check the date and time on the device. Incorrect time settings can disrupt encryption protocols. Set up automatic time synchronization over the network in the Date and Time menu.
Use of alternative payment methods
In addition to the classic payment systems, Xiaomi can use payment through the QR-codes that support many banking applications, although this is not strictly contactless technology. NFC, It's a convenient way to pay without a card. The smartphone camera reads the code, and the money is written off.
And there are also ring devices and NFC wristbands that can be synchronized to your phone or used independently, and they write in the same way that your phone does to an emulated card, which is convenient if you're exercising and you don't want to bring your smartphone.
💡
For quick payment, double-press the power button or a special gesture if your version of MIUI supports running a payment application by action.
And remember that loyalty payments are also possible, because many store apps allow you to save loyalty cards and pay for purchases within the store ecosystem using the same online channel, which is especially true for large retailers.
It is important to understand the difference between technology. NFC works at a distance of several centimeters and requires active action (proposal), while QR-The code requires you to open the app and point the camera, and the method you choose depends on your preferences and the equipment of the outlet.
Impact of firmware and region on NFC performance
The functionality of NFC on Redmi 8 Pro may depend on the version of the firmware installed. Global versions (Global) usually have a full set of certificates for working with international payment systems. Chinese versions (CN) may require firmware reflashing or installation of a global ROM to work correctly in other regions.
If you have purchased a device imported by parallel import, make sure that there is global firmware on board. You can check this in the About Phone menu. The presence of Chinese characters in the system menu or the absence of some Google services may indicate the Chinese version.
| Type of firmware | Support for NFC | Interface language | Recommendation |
|---|---|---|---|
| Global | Complete. | Russian, English | Optimal for Russia |
| China | Limited. | Chinese, English | Requires flashing. |
| EEA (Europe) | Complete. | All European | Good alternative. |
| Recovery (Beta) | Unstable. | Depends on the build. | Not recommended |
When changing region, the set of available applications and services can be changed in the phone settings (Menu Region), and it is recommended for users from Russia to install the region Russia or Ukraine (as an alternative for some services) to ensure the correct operation of local payment gateways.
⚠️ Warning: Self-flashing from the Chinese version to the global version can lead to loss of warranty and risk turning the phone into a brick if the process technology is broken.
