The modern smartphone has long ceased to be just a device for calls, becoming a universal key to the digital world, where NFC (Near Field Communication) technology plays a major role. Owners of the popular Xiaomi Redmi Note 10S model often wonder how to activate this module and use it for contactless payment, although in current realities the functionality may be limited to sanctions. Despite the impossibility of direct payment through Google Pay cards of Russian banks, the module remains a useful tool for reading tags, transferring data and interacting with a smart home.
In this article, we will take a closer look at where the MIUIโs short-range contactless settings are hidden, how to test the antennaโs performance, and what alternative use cases are available to users right now, learn about hidden features that are often ignored, and answer questions that arise when you first get acquainted with short-range wireless communication technology.
What is NFC and why is it needed in the Redmi Note 10S?
NFC technology is a wireless standard that allows devices to communicate up to 10 centimeters. In the Redmi Note 10S smartphone, the module antenna is built directly into the back cover or under the display, which provides a stable signal when you bring the device to the terminal or tag. The main advantage of the technology is that devices are instantly paired without the need for complex procedures or passwords, as happens with Bluetooth.
Users often underestimate the potential of this chip, limiting its use to payment systems. But the range of applications is much wider, from automating routine tasks to quickly connecting accessories. For example, you can program your phone to turn on an alarm clock or start a navigator by simply touching a special tag on the bedside table, which is especially convenient in scenarios where hands are busy or instant system response is required.
It is important to understand that all functions require the correct software configuration and the availability of the appropriate software. Xiaomi owners must consider the features of the MIUI shell, which can hide some switches in non-obvious places of the menu.

How to find and how to turn on the NFC module
Activation of the module in Redmi Note 10S does not require a deep dive into the engineering menu, all the necessary switches are brought to the standard settings of the system. However, the path to these can vary depending on the firmware version and regional specifics of the device. The standard algorithm of actions involves moving to the main settings menu, where you need to find the section responsible for connections and wireless networks.
In some versions of the MIUI shell, the switch can be hidden under "Other Wireless Connections" or "Connect and Sharing." If you don't see the icon right away, use the search bar at the top of the settings screen to query "NFC." The system will automatically highlight the desired menu item, which greatly speeds up the on-line process, especially for beginners.

Once activated, the notification curtain (quick access panel) will have an icon that allows you to turn the module on and off with a single touch. This is the most convenient way to control if you use the feature periodically and want to save battery power, although the power consumption of a modern chip is minimal even in the active state. Remember that some functions, such as Android Beam (older versions) or emulating cards, may require additional configuration of applications.

The quickest way to turn on NFC is to lower the notification curtain and click on the icon if it is added to the Quick Access bar.
Google Pay and Alternative Payment Systems
The issue of payment by smartphone is the most pressing for owners of Xiaomi Redmi Note 10S. Previously, the standard solution was Google Pay, which allowed you to link bank cards and pay for purchases with touch. However, due to changes in the operation of payment systems, direct payment with cards of many banks has become unavailable, which requires finding workarounds or using alternative applications.
For those who continue to use foreign bank cards or tokenization-enabled services, the setting remains the same: add the card to the Google Wallet app (or Google Pay), verify it via SMS or bank call, and install the default contactless payment app. In the NFC settings, it is important to select the HCE card emulation mode so that the smartphone can simulate a plastic card.
There are alternative payment methods that work through QR-codes or ecosystems of banks that do not require classical NFC-Some users use emulator apps that create a virtual card, but their work may be unstable and does not guarantee the security of data. We recommend you to follow the official news of banks and Xiaomi regarding updates on payment solutions.
โ ๏ธ Warning: Do not install untested card emulation applications from questionable sources.This could result in your credit card data being stolen or malware infecting your device.
If you are planning to travel abroad where Google Pay is stable, make sure that the settings for the device region are the right setting. Sometimes changing the region in the "Advanced" -> "Region" menu helps to activate hidden features or fix errors in the operation of payment services. It is also worth checking whether the Google Play service is blocked at the carrier or provider level.
Use of the NFC-tagging
One of the most interesting features available to owners of Redmi Note 10S, It is a programmable work with programmable NFC-These little chips can be bought online or get for free in some advertising campaigns, and they can do wonders with smartphone automation, NFC Tools or Tasker, you can tag any command or set of actions.
Imagine a scenario where you go home and you touch a mark on the wall with your phone, and then the phone automatically goes silent, connects to Wi-Fi and launches your favorite playlist, or another scenario: an in-car tag where the navigator makes a route to work and Bluetooth connects to the audio system, and the options are limited only by your imagination and the functionality of the automation application you choose.
What labels are better to buy?
You need an app to write the tags. The process is simple: you choose an action (launch an application, send a message, change settings), write it down to a clean label, hold the phone to the back of the device, then the tag is ready to use. You can create complex macros that will be executed in sequence, saving user time in everyday situations.
| Type of tag | Memory capacity | Recording speed | Best application |
|---|---|---|---|
| NTAG213 | 144 bytes | Tall. | Simple commands, links |
| NTAG215 | 504 bytes | Medium | Device pairing, profiles |
| NTAG216 | 888 bytes | Low. | Business cards, complex data |
| MIFARE Classic | 1 Kb | Medium | Copying access keys |
Reading and writing information to tags
Functional Redmi Note 10S Not only does it allow you to read information, but it can also be written to compatible tags, which can be useful for creating smart business cards, where when you touch your phone, the contact is automatically saved to the phone book of the other person. To implement such tasks, specialized applications that have access to the NFC-the controller and can form data packets in the desired format.
When recording information, it is important to consider the type of data. A smartphone can record text messages, URL-Addresses, contacts, calendar events, and even apps. For example, you can create a tag that, when you touch it, opens a specific site or social network profile, which is convenient for marketing purposes or for personal use, to quickly share content with friends.
The recording process takes a few seconds and requires the NFC module to be turned on and the smartphone screen unlocked. Once successfully recorded, the label is often recommended to be blocked from further overwriting so that the data is not accidentally altered. This is especially true if you distribute the tags to other people or use them in public places.

Check the label you recorded right after you create it. Hold your phone up to it again and make sure it's done correctly. If the tag doesn't read, try changing the angle of tilt or removing the case.
Diagnostics and Solving NFC Problems
If the NFC module on the Xiaomi Redmi Note 10S has stopped working or is unstable, the first thing to do is to conduct a basic diagnostic. Often the problem is not in the hardware, but in a software failure or settings conflict. Check if the module is on in the settings, if the flight mode is activated and if the case does not block the antenna. Thick metal or magnetic cases can shield the signal, making communication impossible.
If the phone doesnโt see tags or payment terminals, try clearing the cache of the Google Pay app or Google Play Services. It also helps to reboot the device, which resets temporary errors in the driver operation. If the problem persists, check for system updates in the About Phone menu, as developers often release patches that fix communication errors.
โ ๏ธ Warning: If the phone fell or was exposed to moisture and then stopped working NFC, There's a high probability of damage to the antenna plume, and in this case, the software won't help, and you need repairs at the service center.
For advanced users, the test mode is available through the engineering menu, which can be accessed by typing a special code in the phone, where you can check the antenna status and signal level, but you should use these settings with caution, since improperly changing the parameters can lead to unstable operation of other wireless modules, such as Wi-Fi or Bluetooth.
