Modern wearables have long since ceased to be just pedometers, becoming full-fledged digital satellites that can replace a plastic card in the store. Owners of Xiaomi and Redmi smartphones often wonder whether they can be used for contactless payment, because it greatly simplifies everyday purchases. NFC (Near Field Communication) technology has become the de facto standard for flagship and mid-budget devices, but in the model range of the brand, the situation is not as clear as it may seem at first glance.
Many users mistakenly believe that the presence of the manufacturer's logo on the box guarantees support for all advanced features, but the regional version of the gadget often dictates its rules. Global modifications can lose certain features due to licensing restrictions or the peculiarities of payment systems in different countries. In this article, we will discuss in detail which models of smart watches and fitness bracelets have a built-in near-field communication chip and how to make them work with your bank card.
It is important to understand that even with an NFC module, the setup process can vary depending on the operating system of your smartphone – Android or iOS. In addition, the functionality often depends on the application through which the pairing occurs: Mi Fit, Zepp Life or Xiaomi Wear. Below we will provide comprehensive information so that you can make an informed choice when buying or configuring your existing device correctly.
NFC Technology in Xiaomi Ecosystem: How It Works
The contactless feature in Xiaomi devices is implemented through a special microchip built into the body of the gadget. This chip allows you to transfer encrypted data to the reading terminal at a distance of several centimeters. In the context of smart watches, this is used mainly for emulating bank cards, office access cards or travel tickets.
The other half is the software and services that run the module. In Russia and CIS countries, NFC work on the watch is often tied to Mi Pay or third-party applications for emulation of cards, since support for Google Pay on the watch itself with the Wear OS operating system from Xiaomi is limited to certain models. Most trackers use the method of copying the card ID (UID) or tokenization through the bank application.
It is worth noting that connection speed and stability depend on the firmware version and the region for which the device is released. Chinese watches (CN) often have more out-of-the-box functionality, including support for local payment systems, which may not be available in global (Global) versions.
💡
Always check box markings: Global Version guarantees the availability of Russian language and adapted services, but may limit some NFC features compared to the Chinese version.
Full list of Xiaomi watch models with NFC support
The brand’s range of wearable electronics is huge, and having a communication module is not an end-to-end feature across all lines.NFC is mainly found in the Xiaomi Watch series and some advanced versions of the Mi Band. Budget entry-level fitness trackers tend to be stripped of this option for the sake of lowering cost and increasing battery life.
The flagship Xiaomi Watch lineup is almost always equipped with the necessary chip, both for classic round-dial models and more sporty versions. At the same time, the situation in the Redmi Watch lineup is floating: support is only available in older models, while the basic versions (Lite, Active) most often do not have a module.
For a long time they did without a chip, but since a certain model, the manufacturer began to implement the technology in the version of the NFC Edition. It is important not to confuse the usual bracelet and the special version, as they can be identical, differing only by the presence of a logo on the back panel or packaging.
Differences between NFC Edition and conventional models
There are many devices on the market that are labeled NFC Edition, not a marketing ploy, but a hardware difference inside the case, which has an additional antenna and controller that are not available in the basic versions, and if you buy a device without this console, you will not be able to physically activate contactless payment even if you install a third-party firmware.
The price difference between the regular version and the NFC Edition is usually 10-15%, which is a reasonable overpayment for additional functionality. However, it is worth considering that in global versions of the NFC functionality can be reduced. For example, in some regions, you can only pay for transportation or purchases in partner stores through the Mi Band, but you can not tie an arbitrary bank card.
There are also software differences: Chinese versions of NFC Edition often allow access cards (intercoms) to be recorded directly through the app, while global versions may require third-party utilities or no UID card recording at all for security reasons, an important nuance for those planning to use the watch as a drive-in key.

Instructions: How to activate and configure NFC on a watch
The setup process can vary depending on the model and the application used, but the overall algorithm remains similar.First of all, make sure that your smartphone has Bluetooth enabled and geolocation. Then open the device management app (most commonly Zepp Life or Xiaomi Wear) and navigate to your gadget profile.
In the device settings menu, find the section associated with payment or NFC. If the module is supported, you will see the option "Add card" or "Mi Pay." The system will prompt you to enter your bank card details or scan it with the smartphone camera. The data is encrypted and transmitted to the protected element of the watch.
Once the card is successfully tied, you will need to wake up the watch screen, find the Payment widget, and hold your wrist to the terminal to make a purchase, and some models require confirmation of the operation by pressing a physical button or touching the screen, which is a security measure in case the device is lost.

Compatibility with banks and payment systems
Payment functions are directly dependent on your bank’s support, and not all financial institutions allow cards to be linked to third-party wearables, especially in the face of changing laws and sanctions, and the cards of major federal banks are currently the most stable.
It is worth distinguishing between Mi Pay ( Xiaomi’s own service) and card emulation.Mi Pay requires installing a separate plugin and authorization through Mi Account. UID) It works differently and may not require bank involvement, but is not suitable for all types of cards (e.g. dynamic cards). CVV-code-coding will not work).
For iPhone users, the situation is more complicated: due to the closedness of the iOS system, adding cards to Xiaomi watches is often impossible or severely limited functionally compared to Android smartphones. iPhone owners are advised to check the list of compatible banks in the Xiaomi Wear app in advance.
| Model of the device | Presence of NFC | Support for Mi Pay | Recording access cards |
|---|---|---|---|
| Xiaomi Watch S1 Active | Yes. | Yes. | Yes. |
| Redmi Watch 3 | Yes. | Yes. | No. |
| Mi Smart Band 7 NFC | Yes. | Limited. | Yes. |
| Redmi Watch 2 Lite | No. | No. | No. |
| Xiaomi Watch Color 2 | Yes. | Yes. | Yes. |
💡
The access card (intercom) recording function is unstable with new generation encryption cards, with a copy success rate of around 60-70%.
Frequent problems and ways to solve them
Even if you follow all the instructions, users can face difficulties, and one of the most common problems is that the terminal in the store does not see the watch, which can be due to a discharged battery (power saving mode turns off the NFC), too thick a case on the hand, or the wrong method of payment at the cashier's terminal.
Another problem is that you can't add a card, often because the bank blocks a transaction because it's suspicious, or the watch app needs to be updated, and it's worth checking if the NFC chip itself is full of memory, because some models allow you to store no more than 5-10 cards at a time.
In rare cases, there is a spontaneous shutdown of the function after updating the firmware of the smartphone, in which a complete reset of the clock to factory settings and re-pairing helps.
⚠️ Note: When using the access card emulation (intercom) function, remember that some modern security systems use dynamic keys. A card copied for a clock may stop working after a while or not work at all if the access system requires a unique crypto key that cannot be copied.
⚠️ Note: Do not try to reflash regional versions of the watch yourself (for example, turn the Global into a new watch). CN) unlock NFC. This action is almost guaranteed to lock the device on the IMEI or disrupt the Bluetooth module, making the gadget useless.
Comparison of functionality: Xiaomi vs. competitors
When it comes to wearable electronics, Xiaomi is often compared to Huawei and Apple.If the Apple Watch offers the most seamless payment integration for iPhone owners, then Xiaomi devices benefit in autonomy. Xiaomi watches with NFC can last up to 14-20 days without recharging, whereas competitors require daily charging.
Compared to Huawei, the Xiaomi ecosystem often offers more affordable prices with similar functionality. However, Huawei Health software is considered more stable in working with payment modules in some regions, the choice between them often boils down to interface preference and design.
The main advantage of Xiaomi NFC watches is versatility, which is suitable for both sports and everyday wear, allowing you to leave your phone at home. The ability to quickly pay for coffee or fare just by swinging your hand saves time and adds comfort, justifying the presence of this module in the device.
