Smartphones are no longer just a means of communication, but a universal tool for everyday tasks. One of the most popular features is the ability to contactlessly pay for purchases in stores, gas stations and in transport. Owners of Xiaomi, Redmi and Poco devices often wonder how to activate this service and make it work stable. NFC (Near Field Communication) technology provides secure data exchange at a short distance, which allows you to use a phone instead of a plastic card.
The setup process may seem complicated at first glance, but it actually takes only a few minutes. You only need a stable Internet connection and a linked bank card. It is important to understand that not all budget models are equipped with the necessary module, so checking the specifications is the first step. In this article, we will discuss in detail the activation process, how to circumvent restrictions and solve typical errors that occur when trying to make a payment.
Checking for the presence of an NFC module and activating it
Before you start adding cards, you need to make sure that your device technically supports contactless communications. Many users mistakenly assume that if there is a corresponding item in the menu, the module works exactly, but this is not always the case. In some cases, the software shell may hide the absence of a physical chip or it may be disabled at the firmware level for a particular region.
The first way to check is a visual inspection of the back of the device or tray for SIM-Often, manufacturers put on a logo. NFC If there are no external signs, you should consult the technical specifications on the official website or in the Settings application. The presence of the module ensures that the device can read the tags and transmit payment data to the terminals.
To activate the function, perform the following actions:
- 📱 Open the swipe notification curtain from top to bottom and find the icon NFC, touch it to turn it on.
- ⚙️ Go to the Settings menu → Connection and sharing → NFC and activate the slider.
- 🔍 In the search for settings, enter a request "NFC" Select the system's proposed transition option.
Once the module is turned on, the system may suggest selecting the default payment app, which should include Google Pay or an alternative service you plan to use, and if the module does not turn on or quickly drains the battery, there may be a software failure that requires the device to restart.
⚠️ Note: Some global versions of the firmware MIUI or HyperOS menu item may be called Contactless Payments or hidden under Additional Features".
Installation and configuration of Google Pay and alternatives
The main tool for contactless payments on Android remains the service from Google. Despite changes in the operation of payment systems in different regions, the principle of the application remains the same: you will need a Google account associated with the device and installed Google Pay application (or its analogue relevant to your region, for example, Mir Pay or banking applications with the function of tokenization).
The process of adding a card starts with launching the app and logging into your profile, the system automatically requests permission to use the camera to scan the card or enter data manually, and it is critical that the phone number listed in the bank matches the number to which the Google account is registered, otherwise the bank may reject the link for security reasons.
Follow this algorithm for successful binding:
- 💳 Launch the application and click the "Add card" button or plus in the corner of the screen.
- 📸 Scan the card with the camera or enter the number, expiration date and CVV-manually.
- ✅ Accept the terms of the agreement and verify through SMS or a call from the bank.
In some cases, the bank may require confirmation of the transaction through a separate banking application: make sure that the smartphone has all the necessary security certificates. If the card is not tied, check whether the device has root rights or modified firmware, as payment systems block work on the modified devices.
⚠️ Note: When using custom firmware or unlocked bootloader, Google Pay may not work due to a security breach.
Set up priorities and security elements
Once the cards are successfully linked, it is important to set your priorities so that when you bring your phone to the terminal, you debit the account you want. By default, the card you add is the last one, but it's easy to change that setting, and you need to set up a mandatory unlock before you pay.
On the menu. NFC The security element is the location of the payment tokens, and for most users, the best option is to use it "HCE Wallet" (Host Card Emulation), as it is a standard software solution compatible with Google Pay "SIM-Cards are rarely required and only for specific operator services.
☑️ Check before the first payment
To change the main map, follow the following steps:
1. Open the payment system application.
2.Click on the image of the desired card to make it active.
3. Or go to the NFC settings and in the "Payment by default" option, select the required application or card.
It is also recommended to enable fingerprint or face confirmation of payments, which will prevent accidental debits if the phone simply ends up near the terminal unlocked, and in the security settings, you can find the option "Require screen unlock for payment" that you should activate.
Compatibility table of popular Xiaomi models
Not all Xiaomi devices are equipped with a short-range communication module. Generally, the flagship Mi and Xiaomi series (digital series), as well as many mid-size Redmi Note models support this technology. Budget models of the Redmi series (without the Note console) and the entry-level Poco often lack NFC to reduce cost.
Below is a table that helps you quickly determine the availability of the module in popular series. Note that even within the same model, there may be versions for different markets (Global, China, India), which may differ in configuration.
| Series of devices | Presence of NFC | Note |
|---|---|---|
| Xiaomi 13 / 14 / 15 | ✅ There is. | All models of the flagship line |
| Redmi Note 12 / 13 | ✅ Available (in Pro versions) | In the basic versions may not be available. |
| Poco X5 / X6 | ✅ There is. | Supports Google Pay |
| Redmi 12C / 13C | ❌ No. | Budget segment without module |
| Xiaomi Mi Band (bracelets) | ❌ No. | Only Watch models with NFC |
Why are there no NFCs in cheap models?
Solving typical payment problems
Even with the right setup, users can encounter situations where the terminal is not reading the phone. Most often the problem lies in the case. Metalized cases, magnetic latch cases or thick protective pads can shield the signal. In such cases, it is recommended to remove the case during payment or use models without metal inserts.
Another common reason is the phone's positioning is wrong. The NFC antenna in Xiaomi smartphones is usually located at the top of the back, next to the camera module. You need to put the phone to the terminal in this section, not in the middle or bottom of the case. The movement should be smooth, without sudden jerks.
If the payment does not pass, try the following:
- 🔄 Reboot your smartphone to reset temporary Google services errors.
- 📶 Make sure your internet connection is active (although the payment is offline, the initial authorization requires a network).
- 🗑️ Remove the card from the app and add it again by updating the security tokens.
⚠️ Note: If the terminal says "Bank error" or "Card is invalid", the problem may be on the card issuer's side, not on the phone.
Use of Mi Pay and other services
In some regions, especially in China and CIS countries, Mi Pay is actively developing its own payment system. MIUI/HyperOS It allows you to link cards directly through the system application "Mi Wallet" (Mi Wallet), which is convenient because it does not require the installation of additional software, but the list of supported banks can be limited compared to Google Pay.
💡
Use Mi Pay if Google Pay is not supported in your area or is not running smoothly.This native solution often has deeper integration with the system.
To set up Mi Pay, you need to:
1. log into the Wallet app (or download it through GetApps).
2. Select region (often you need to change region in your phone settings to China or India if the service is not working in your region).
3. Add a map by following the instructions on the screen.
It is worth noting that the tokenization protocol in Mi Pay is different from Google Pay, so the same terminals can react differently to different services. If one method did not work in a particular outlet, it makes sense to try an alternative payment method or another tied card.
💡
Payment stability depends not only on the phone, but also on the compatibility of the payment token with the store terminal.
