Xiaomi smartphone owners often wonder how to quickly and safely pay for purchases in stores just by attaching a device to a terminal. NFC (Near Field Communication) technology allows you to transfer data over short distances, which is ideal for contactless payment through banking applications. However, on Chinese-brand devices, setting up this feature sometimes causes difficulties due to the features of the MIUI shell or HyperOS.
For SberPay or other payment tools to work, the communication module must work properly and the security system does not block access to the chip. In this article, we will examine all the nuances of activation, check security settings and fix common errors that interfere with transactions.
Modern models of Redmi, POCO and flagship Xiaomi are equipped with reliable communication controllers that are ready to work by default. You do not need complex manipulations with root rights, just competently configure the software part in the menu of your gadget.
Hardware compatibility check and module activation
The first step should always be to check for the communication module in your device, as not all Xiaomi models are equipped with budget. NFC-You can see this by looking at the specifications on the box or the official specifications on the manufacturer's website. If there's a module, it needs to be activated through the system menu.
Go to your smartphone settings and look for Connect and Sharing or Additional Features, and there's a switch that triggers the antenna, and without activating that slider, no app can see your bank card.
- π± Open the settings menu and select "Connect and share".
- π‘ Find a line "NFC" and move the slider to the active position.
- π Make sure that the item position menu (or contact payment) selects the default Google Pay or SberPay app.
Note that in some versions of MIUI firmware, the path to settings may be slightly different. If you don't find the switch right away, search by settings by typing the word "NFC." It's also important that the smartphone screen is unlocked when you reach the terminal, otherwise the transaction won't go through.
β οΈ Warning: If the "N" icon does not appear in the notification curtain after the switch is turned on, or disappears immediately, this may indicate a hardware malfunction of the antenna or a conflict with a case containing metal elements.
Setting up the SberPay application and linking the card
The main tool for contactless payment on Xiaomi devices with support for Google services is the SberPay application, which allows you to turn your smartphone into a virtual analog of a plastic card. The binding process takes only a couple of minutes, but requires careful input.
Download the official app from the Google Play store or AppGallery (if you have a new Huawei or Honor, but here we are talking about Xiaomi with GMS). Launch the program and log in using your SberID. The system automatically prompts you to add an already released card or issue a new virtual one.
βοΈ Checking before linking the card
When you add a card, you need to confirm ownership through a code from SMS, then the card will appear in the list of available for payment, it is important that there are funds on the card, and the limits on online transactions are not blocked by the bank itself.
In SberPayβs settings, you can enable Pay without the Internet, which allows transactions to be made even when the network is not available using tokenization, especially in places with poor cellular coverage.
HCE configuration and security elements
HCE (Host Card Emulation) technology allows you to emulate the operation of a plastic card directly by the processor of a smartphone, bypassing a special Secure Element chip. On Xiaomi devices, this is the main method of working payment systems. Correct HCE configuration is critical for the stability of connections.
To check the settings HCE Go to the Settings menu β Connection and sharing β NFC β Security element. This should be the value. HCE Wallet or Simulation of the map HCE. If chosen "SIM-Card, payment through applications will not work.
| Setup parameter | Recommended value | Where to find out. |
|---|---|---|
| NFC module | Included. | Quick settings/menu |
| Security element | HCE Wallet | NFC menu |
| Payment off screen | Permitted. | NFC menu |
| Default application | SberPay / Google Pay | NFC menu |
Also in this section, there is the option "Pay with the screen off" which is recommended to activate for convenience: this will allow you to pay for purchases, not including the display of the smartphone, simply by unlocking it with a fingerprint scanner or face.
What is data tokenization?
Solving MIUI and Access Rights
MIUI is known for its aggressive energy saving system, which can kill the background processes of payment applications. If payment stops or the application closes on its own, you need to configure auto-start and permissions.
Go to the battery settings and find the SberPay app, set the "No Limits" mode, which will prevent the system from turning off the communication modules necessary to conduct a transaction in the background.
- π Open the "Security" app on your desktop.
- βοΈ Go to the "Permissions" section" β "Auto-start".
- β Find in the SberPay list and activate the slider.
Also, check the permissions for the app itself. It needs access to NFC, the internet, and in some cases geolocation to locate the terminal (though this is rarely required).
β οΈ Warning: Do not clear the cache and data of SberPay applications unnecessarily.This can lead to de-logging and the need to re-attach cards, which is sometimes temporarily blocked by the bank for security reasons.
Influence of covers and accessories on the signal
Physical obstacles can significantly weaken the NFC signal. The antenna in Xiaomi smartphones is usually located at the top of the body, often near the main camera module.If you use a thick protective case, especially with metal inserts or a magnetic fastener, communication may be interrupted.
Try to remove the case and try again, and if you don't have the case, it's the accessory that's the problem, and the metal backs or the pop sockets are also shielding the signal.
π‘
Use cases with a cutout at the top of the case or thin silicone models that minimally affect the range of the NFC antenna.
Itβs also worth checking if there are other sources of interference near the phone, such as powerful magnets or other electronic devices with active NFC. In rare cases, stickers or thick protective glass can create a gap that exceeds the operating range of 4-5 cm.
Alternative payment methods and PayPass
If standard settings through Google Pay or SberPay donβt work (for example, on newer models without Google services), alternative methods can be used. Some users use emulator apps or virtual cards of other banks that support the Mir Pay standard.
For devices deprived of Google services, the use of quick payment widgets inside banking applications or payment for the Internet becomes relevant. QR-code through SberBank Online, although this is not NFC-payment in its pure form, functionally it replaces the trip to the terminal.
Owners of older models may face a lack of tokenization support, in which case the bank may offer to issue a special SIM card with NFC support, but this method is gradually becoming a thing of the past and requires replacing the SIM card in the office of the operator.
π‘
The stability of NFC on Xiaomi is 90% dependent on the right energy saving settings and the choice of HCE as a security element.
