The modern smartphone has long ceased to be just a device for calls and instant messengers, turning into a full-fledged digital wallet that is always at hand. Owners of Xiaomi devices often wonder how to activate contactless payments to avoid carrying plastic cards. The setup process is simple enough, but requires attention to detail and compliance with certain conditions on the part of the bank and the operating system.
The basis for transactions is NFC (Near Field Communication), which provides wireless communication over short distances. Without a working NFC module, any attempt to pay with a phone will be doomed to failure, so checking for this chip is the first and most critical step. In this article, we will discuss in detail how to prepare your Redmi or Poco for payment systems.
It should be noted that the success of the operation depends not only on the settings of the phone, but also on the policy of the card issuing bank. Some financial institutions may block the addition of cards to third-party services or require additional verification through SMS. On devices with global firmware (Global ROM) problems usually do not arise, while the Chinese version (CN ROM) may require a change of region for the correct operation of Google services.
Check the availability and operability of the NFC module
Before you start setting up, you need to make sure that your particular device is equipped with the necessary hardware. Not all models in the budget segment have an integrated NFC chip, even if they look identical to the more expensive versions. To quickly check, lower the notification curtain and find the NFC icon; if it is not in the list of fast switches, this does not mean that the module is not.
A more reliable way is to go to the system settings. Go to the Settings → Connection and Sharing menu (or Additional Features on older versions of MIUI). If the NFC option is not on this list, then, alas, your smartphone hardware does not support contactless payment, and it is impossible to activate this feature software.
It's also important to check if the module itself is on, sometimes it can be turned off by default or previously by the user to save power, in the same menu, activate the slider to start the chip, and once turned on, the phone may request permission to use geolocation, as this is required for some payment protocols to work.
- 📱 Open the notification curtain and look for the icon. NFC.
- ⚙️ Go to Settings and use a search by word "NFC".
- 🌍 Make sure that the item "Location of the element" is selected SIM-card 1 HCE Wallet.
- 🔄 Restart the device if the module does not respond to the switching on.
⚠️ Warning: If you bought the phone from hand or on a marketplace, make sure it's a global version.The Chinese versions of Xiaomi often don't have a single phone. NFC-antennas, even if the model name has the letters "N" or "Global".
Preparing a Google account and installing apps
Contactless payments on Android devices, including Xiaomi, require a properly configured Google account. It is Google Play services that are responsible for tokenizing your data, so login is mandatory. Make sure that the device has an up-to-date Google Play Services installed, as outdated versions may not support new security protocols.
The main tool for most users is the Google Pay app (or Google Wallet) download it from the official Play Market app store. If you have a Chinese-based device without Google services preinstalled, they need to be manually installed through the Google Services Framework installer, which requires additional manipulation.
In addition to the main Google app, you will need an official app from your bank, which is where the primary card binding and identity verification takes place. Banking apps often require additional security certificates, especially on Xiaomi devices with their aggressive MIUI Security protection system.
After installing all the necessary components, it is recommended to clear the cache of the Google Play Services and Google Pay applications. This will help avoid conflicts when you first start. Go to Settings → Apps → All applications, find the right services and select Clear Cache.
Adding a bank card to the system
The process of adding a card is standardized, but can have nuances depending on the bank. Open the Google Pay app and click "Add card" button. The system will suggest scanning the card through the camera or entering data manually. The scan usually works correctly, but it is better to double-check the entered numbers.
After data entry CVV-If you have the code and the expiration date, the bank will send a verification request. SMS-A message, a push notification from a banking application or an automatic call. At this stage, it is important that the phone has active Internet, preferably mobile, rather than Wi-Fi, to avoid problems with location.
Some banks require acceptance of terms of use of tokenized payments. Carefully read the text of the agreement, especially the clauses on limits and liability. Once successfully linked, the card will appear on the list of available means of payment and will be marked as "Ready to use".
- 💳 Press "+" In the Google Pay app to start adding.
- 📸 Scan the card or enter a number, deadline and CVV manually.
- 📲 Confirm ownership of the card through the code from SMS orbell.
- ✅ Accept the terms of the agreement with the payment system and the bank.
If you don't add a card the first time, don't panic. Often the problem is an unstable connection or a temporary failure on the bank side. Try switching from Wi-Fi to mobile Internet and repeating the procedure.
Setting up priority and security parameters
After adding a card, it is important to adjust the security settings so that payments are quick and without unnecessary requests. In the Google Pay settings, you can choose the method of unlocking for payment. It is recommended to use biometrics (fingerprint or facial scanner), as this greatly speeds up the payment process at the checkout.
You should also pay attention to the order of the cards. If you have multiple cards added, the first card on the list will be offered as the default payment, you can change the priority manually or allow the system to select the card automatically based on the purchase history in certain stores.
☑️ Checking security settings
An important aspect is to set up notifications, and turn on the sound and vibration when you make a successful payment, which will help you monitor transactions in real time and immediately notice if the payment has been twice or the amount has been incorrect.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Lock screen | Pin code/Biometry | Necessary to work for NFC |
| Notifications | Included | Control of write-offs |
| Priority of the map | Main map | Speed of payment |
| Geolocation | Included. | Required for some banks |
⚠️ Warning: Don't use simple graphic keys or passwords like "1234" to pay for your phone, and if you lose your phone, attackers can access your finances if the security is weak.
Features of work on different versions of MIUI and HyperOS
The interface of the MIUI shells and the new HyperOS may differ, which affects the location of NFC settings. In recent firmware versions, Xiaomi introduces its own payment solutions such as Mi Pay, but in most regions, Google Pay still dominates. If you upgrade to the new version of the OS, check if your NFC settings have reset.
Users of Chinese firmware versions may face a lack of Google services by default, in which case setting up contactless payment becomes a more complex process, requiring installation of the Google Framework through special developer menus or third-party installers. Without this step, Google Pay simply will not start.
Also worth mentioning is the Safe Folder or Second Space feature.If you use these features to separate work and personal data, keep in mind that Google Pay apps must be installed and configured in the main space.
What to do if Google Pay is missing after the firmware update?
Owners of older devices that don’t receive security updates should be careful, because banks may gradually stop supporting older versions of Android due to security risks, in which case the only way out is to use a physical card or switch to a new device.
Solving Common Payment Problems
Even when properly configured, there can be situations where the terminal in the store does not see the phone, one of the common reasons is a thick case or a metal plate on the back (for example, for a magnetic holder in a car), the metal shields the NFC signal, making it impossible to read data.
Another common problem is a dead battery. Unlike some other systems, standard NFC on Xiaomi may not work if the battery has dropped below a critical level (usually 10-15%), even if the phone is still on.
If the terminal says "Transaction error" or "Card not accepted," try to bring the phone up the other side. The location of the NFC antenna in different Redmi and Mi models is different: it can be in the top of the case, in the center or next to the camera. Experimentally find the "sweet spot" of your device.
- 🔋 Check the battery level (should be) >15%).
- 📵 Remove the cover, especially if it has metal elements.
- 📍 Change the position of the phone relative to the terminal (top/bottom/center).
- 🔄 Make sure the phone screen is unlocked at the time of application.
💡
When paying in transport or subway turnstiles, bring your phone up quickly and clean up immediately after the vibration. Long hold can lead to double readout or error.
In cases where nothing works, try removing the card from the app and adding it again. Sometimes the card token on the bank server may freeze or expire, and re-association updates the security keys.
