In this article, we will discuss in detail all the nuances of connecting bank cards through NFC-module and physical installations SIM-You will learn why some models allow you to pay in the store with one touch, while others require complex manipulation of emulator applications. Understanding the architecture of Mi Pay and third-party services will help you avoid disappointment when buying.
It is worth noting that the ecosystem of Xiaomi is heterogeneous: the functionality of fitness bracelets Mi Band and full-fledged smart watches Mi Watch significantly differ. We will look at the technical features of each line so that you can maximize the capabilities of your wearable device.
Differences in models: which clocks support cards
The first thing that users encounter is confusion about names and functionality. Not all Xiaomi-branded devices have a built-in payment chip or a SIM slot. Mi Band series fitness bracelets (starting with version 6 and later) often feature an NFC module, but it only works with transport cards or corporate passes in certain regions.
Full support for bank cards via Google Pay or Mi Pay is only available in the line of smartwatches such as the Mi Watch, Mi Watch Lite (not all revisions) and flagship Amazfit models, which are formally ecosystem-specific. It is important to distinguish between global and Chinese versions of devices, as the software in them can be radically different.
- 📱 Mi Watch: Full OS, eSIM support and NFC Payment (depending on the region).
- ⌚ Mi Band 6/7/8 NFC: Only transport cards (works mainly in China and Russia with cards).
- 🏃 Amazfit GTR/GTS: Mi Pay support in some models, but often limited to regions.
⚠️ Note: Buying a device in the Chinese market (CN Version, you risk getting a gadget that has a module in it. NFC It will not work with European or Russian banking systems due to software restrictions.
To check for support for features on a particular device, you need to go to the official specifications on the manufacturer's website. Look for the acronyms NFC and eSIM. If the specifications indicate only Bluetooth support, then connecting a card for payment or calls without a phone is physically impossible.
NFC setting and bank card binding
The process of adding a payment instrument requires preliminary preparation. Make sure that the watch and smartphone have the latest versions of the firmware and the Mi Fitness application (or Zepp Life for older models), the security of transactions is ensured by the tokenization of data, so the card number itself is not transferred when paying.

It is important to understand that in some regions, standard Google Pay on watches may not work due to lack of Google certification or blocking, in which cases users turn to alternative payment systems such as Mi Pay or services from specific banks if they provide their own applets for wearable devices.
- 💳 Open the Mi Fitness app on your smartphone.
- 🔗 Select the Profile section → My devices. → NFC.
- ➕ Click Add Map and Follow the Instructions on the Screen.
Once the card is successfully linked, it will appear on the list of available means of payment. To make a payment, it is enough to wake the clock and bring it to the terminal. Internet connection at the time of payment is not required, since the token is stored in the secure memory of the device.
Use of the SIM-cards and eSIM in hours
The autonomous communication function is implemented via eSIM (built-in SIM) technology or, in rare cases of older models, via a physical nano-slot. eSIM technology allows you to activate the tariff plan without installing a plastic chip, which saves the interior space of the case and increases water protection.
To activate the service, your mobile operator must support MultiSIM or One Number technology, which allows you to use a single phone number on multiple devices, and the activation process usually occurs through the operator’s application or the watch interface, if supported. OTA-activation.
Path of activation (exemplary):
Settings → Network and Internet → Mobile Network → Add a tariff planAfter the scan. QR-The watch will have access to the mobile network, which allows you to make calls, send messages and use the mobile Internet even if the smartphone is at home or dead.
What happens if the operator does not support eSIM?
⚠️ Attention: Activation of eSIM may consume additional battery power.It is recommended to turn off the mobile network in standby mode if you are in Wi-Fi coverage.
Comparison of the functionality of different versions of the software
The watch software can be based on different platforms: Google’s Wear OS or proprietary HyperOS (formerly MIUI for Watch), which determines the range of available features and how to connect cards, and users often confuse these versions, expecting flagship functionality from budget models.
Wear OS devices have full access to the Google Play Store, allowing you to install banking apps directly on your watch. Proprietary systems, such as the Mi Band or Amazfit, work in conjunction with your smartphone and have limited but more energy-efficient functionality.
| Characteristics | Wear OS (Mi Watch) | Proprietary OS (Mi Band/Amazfit) | Lite Version |
|---|---|---|---|
| NFC payments | Google Pay / Mi Pay | Transportation / Mi Pay (Ogric) | No. |
| eSIM/Calls | Support for eSIM | No (Bluetooth only) | No. |
| Installation of applications | Play Store | Only from the list. | No. |
| Autonomy | 1-2 days | 7-14 days | 7 days |
The choice between versions depends on priorities: if you want autonomy and basic tracking, proprietary systems win. If you want a full-fledged smartphone on your wrist with the ability to install messengers and cards, the choice falls on Wear OS.
💡
The key difference between the software versions is the ability to install third-party applications and the method of authorization of payments.
Solving Connection Problems
Even if all instructions are followed, technical failures can occur, often because regional settings are incompatible, for example, a card issued in one country may not be accepted by the payment system of a watch configured in another region.
Another common mistake is the lack of security updates: banks require current patches to work with tokens. Check if time-date synchronization is enabled, as out-synchronization for more than a minute can block the use of the tokens. SSL-connection to the bank server.

💡
If you have frequent payment failures, try clearing the Mi Fitness app data on your phone (Settings → Applications → Mi Fitness → Memory → Clear Data), then re-couple the watch.
Payment security and confidentiality
Using a watch for payments is considered safer than a plastic card, with each transaction generating a one-time code, so even when intercepting data, fraudsters will not be able to use it, and often requires that the watch be unlocked (on the wrist) to confirm payment.
In case of loss of the device, it is recommended to immediately use the remote lock function through the Find My Device application or the Xiaomi account management interface, which will block access to payment tokens stored in the memory of the gadget.
⚠️ Warning: Never give a pin code from a card to outsiders or write it down in notes on your phone synchronized with your clock.
Check the list of active devices in your bank’s app regularly.If you sold a watch or gifted one, be sure to complete a factory reset to delete all personal details and payment profiles.
