The modern smartphone has long since ceased to be just a means of communication, becoming a universal tool for financial management. Owners of Xiaomi, Redmi and POCO devices often wonder how to quickly activate contactless payment functionality so as not to carry plastic cards. NFC (Near Field Communication) technology provides secure data transfer over short distances, making the purchase process in the store as fast and convenient as possible.
However, despite the popularity of the technology, many users have difficulty initially configuring or don’t understand why the feature doesn’t work on their particular model. In this article, we’ll take a look at all the steps of connecting, from checking hardware support to linking a bank card to a digital wallet, learn how to properly configure Android to use Google Pay, Mi Pay or alternative services, and what to do if payment doesn’t pass at the checkout.
Contactless payment is not just a fashion, but a real time saving and increased transaction security. When you pay with your phone, your card number is not transferred to the terminal, which minimizes the risk of data theft. Let's figure out how to turn your Xiaomi smartphone into a full-fledged payment tool in a few simple steps.
Verification of hardware support and activation of the module
The first and most important step is to make sure your device is physically equipped with an NFC module. Not all Xiaomi and Redmi budget models have an integrated chip, so blindly following instructions without checking the specifications can be a waste of time.
To check for a module, you need to go to the system settings. Search for settings, type in the acronym NFC or the word "contactless." If you have a module, you will see the corresponding menu item. If the search did not give anything, chances are that your model does not implement this feature hardware, and software will not be able to enable it.
Once a menu item is detected, activate the function. In newer versions of the MIUI shell and HyperOS, the switch may be in the notification curtain or in the Connection and Sharing section. Make sure the slider is activated and lit in blue.
- 📱 Open Settings and select Connection and Sharing».
- 🔍 Find a point. NFC and activate the switch.
- 📡 Enable the option of Emulator Mode to use your phone as a card.
- 💳 Select the “Security Element” and specify «SIM-map «HCE Wallet».
⚠️ Note: If you are using the old SIM-map 5-7 Years ago, it may not support security features. NFC. In this case, a replacement will be required. SIM-cards of the operator to the new with support of technology.
Setting up the security element and payment applications
Once the module is enabled, the system must determine the payment methods available, and the key here is to choose the right security element, which is the component responsible for encrypting the card data. NFC You will see the item "Security Item Location" or "Security Element". For most payment systems in Russia and the CIS, the best choice is to use the security element. HCE Wallet or embedded chip SIM-Cards if the operator provides such services.
The main payment application must be installed and configured. For global versions of Android, Google Pay (or Google Wallet) is the standard. Xiaomi device owners can also use the proprietary Mi Pay service, which often works more stable with Chinese banks’ cards, but requires a separate region setting.
It's important to understand the difference between apps. Google Pay acts as an intermediary between the bank and the terminal, tokenizing data. Mi Pay can work directly with the phone's chip. When it first launches, the app will request permission to access NFC and geolocation, which are mandatory requirements for the service to work.
☑️ Preparation for payment settings
Adding a credit card to Google Pay and Mi Pay
The process of adding a card is almost identical in most payment systems, but has its own interface nuances: Open the installed application, click the Add Card button or the + icon. The smartphone camera will automatically go into scan mode. Point the lens on the front of the plastic card so that the number is clearly visible in the frame.
If automatic recognition fails, you can enter the data manually, the system will request the card number, expiration date and CVC/CVV code (three digits on the back). Once the data is entered, the bank will send the SMS code to verify the owner, enter the code in the appropriate field, and the card will be activated for payments.
It is worth noting that some banks may require additional confirmation through their own app, in which case the screen will prompt you to go to the bank client to authorize the transaction, which is a normal security procedure aimed at protecting your funds.
| Parameter | Google Pay | Mi Pay | Yandex Key |
|---|---|---|---|
| Type of tokenization | Virtual account | Virtual account | Virtual card |
| Support for maps of the world | Limited* | Complete. | Complete. |
| Internet dependency | Not required | Not required | Required periodically |
| Working without unlocking | Required (dactyl/face) | Required. | Required. |
*Note: Support for MIR cards in Google Pay depends on the current policies of Google and the particular issuing bank.In some cases, MIR cards may not be added to GPay, then Mi Pay or Yandex Key is recommended.
Solving Payment Problems and Diagnostics
Even when you set it up properly, there can be situations where the terminal is not reading the phone, most often the problem is the case, metal cases, magnetic clasp cases or too thick protective cases shield the signal, remove the case and try to repeat the payment.
The second common reason is mispositioning. The NFC module in Xiaomi smartphones is usually located at the top of the back, next to the camera. Put the phone in that section to the terminal, rather than the middle or bottom of the case. The movement should be fast and clear, without long retention.
If payment doesn't pass, check the status of the app. Sometimes Android can "dorm in" background processes to save energy. Go to the battery settings, find your payment application, and set "No Limits" or "Autostart" mode, which will prevent the NFC service from being blocked by the power saving system.
