How to Include NFC on Xiaomi: The Complete Guide

Modern Xiaomi and Redmi smartphones have become universal tools that replace wallets, passes and keys. One of the most useful features is NFC (Near Field Communication), which allows you to transfer data over short distances. Many users buy a device without knowing that it already has a contactless payment module built in, and try to find ways to activate where it is physically not, or vice versa, ignore the useful option.

Turning this technology on is not a complicated process, but it requires understanding where to look for the right switch in the shell of MIUI or HyperOS. Unlike other manufacturers, Chinese brands often hide this feature in the sub-menus of Connected or Still, which confuses beginners. We will take a look at all the nuances of activation, setting up Google Pay (or its analogues) and solving common card reader problems.

Before we get to the instructions, it's worth noting that the availability of the feature depends on the specific model of your gadget. Budget models often lack this module to reduce the cost, so the first step should always be to check the technical specifications of the device. If there is a module, then software activation will take no more than a minute.

Checking for the presence of NFC module on the device

The first thing to do before looking for a setting is to make sure that the chip is physically present. Not all Xiaomi smartphones have this module, even if they look the same. Manufacturers often release versions of the same model with different characteristics for different markets.

The fastest way to check is to use the search bar in the settings menu. Click on the magnifying glass at the top of the Settings screen and type in the "NFC" request. If the module is present, the system will immediately prompt you to go to the activation switch. If the search gives you an empty result or a help link that says that the function is not supported, then your device does not have the appropriate hardware.

You can also use specialized applications from the Google Play store, such as NFC Check or AIDA64, which reads hardware information and accurately reports the presence or absence of an antenna. In the technical description on the box or official website, look for the acronym NFC: Yes in the list of specifications.

⚠️ Note: Do not try to programmatically "enable» NFC No root rights or firmware modifications will add a physical antenna to the device body.

Sometimes there is a module, but it's hidden in regional settings, so if you've reflashed the global version to Chinese or vice versa, some features may not show up correctly, and then resetting the network settings or changing the region in the "Advanced" menu helps.

How to find and activate NFC in MIUI and HyperOS

The interface of the MIUI shell may vary depending on the Android version and regional firmware. However, the logic of the menu remains similar. The standard path to the switch is as follows: go to Settings, select Connected (or Shared Connections) and you will see the desired switch.

In newer versions of HyperOS, the structure may have changed. Now, the common path is: Settings → Additional Features → NFC. In some builds, the item is placed directly in the main settings menu if the system determines that you use wireless connections often.

You can use the "Curtain" of notifications to activate quickly. Swipe top-down twice to reveal all the quick access tiles. Find an NFC icon. If it's not on the first screen, swipe right and tap on the pencil (edit) to add a shortcut to a prominent place. This will save time in the future.

Once activated, the status bar will have an icon, and the smartphone is now ready to exchange data.

Contactless Payment and Google Wallet

The main reason users are looking for how to enable NFC on Xiaomi is in-store payment, using Google Wallet (formerly Google Pay), a simple setup process that requires certain security conditions.

First, make sure that the device has Google Play Services installed and a Google account added. Then download your bank app or Google Wallet directly. In the bank app, find the “Play by phone” or “Contactless Payment” section and follow the instructions for linking the card.

When you link it, you can request confirmation via text or a bank call, and once you verify it, it will appear on the list of available payment options, and when you bring the phone to the terminal, the system will select the application you want.

⚠️ Note: If your phone has a bootloader unlocked or a Root right installed, banks may refuse to make payments for security reasons. NFC will not work.

Using NFC for Transport and Passage

Near Field Communication technology allows you to use your smartphone not only as a means of payment, but also as a transport card or electronic pass. In Xiaomi smartphones, this is often the responsibility of the system application “Mi Wallet” or “Wallet”, which is preinstalled in Chinese and some global firmware.

To add a transport card (for example, Troika in Moscow or Podparlodik in St. Petersburg), you need to go to the wallet application, select the type of card and follow the instructions. You usually need to replenish the balance through a tied bank card, after which you can attach the phone to the turnstile in the same way as a plastic pass.

Office passes or intercoms are more complicated. Most modern intercoms use 125 kHz, whereas NFC in phones runs 13.56 MHz. Physically, the phone can't read that key. However, if the intercom uses the Mifare standard, emulation is possible.

Pass emulation often requires third-party apps or special access rights. Some office cards can be copied through the Door Card menu in NFC settings, as long as the phone supports this feature at the driver level.

💡

To copy the intercom keys, try holding your phone right up to the reader, and if the phone vibrates but doesn't open the door, the frequencies don't match, and you can't program it without an external reader.

Removal: Why NFC Doesn't Work

Even after the function is turned on, there may be failures. A common problem is that the phone stops seeing cards or terminals. This may be due to the case. If you use a case with a metal plate, magnetic clasp or too thick, it shields the antenna signal.

Another reason is the application conflict: If you have multiple card emulation apps installed, the system may not know which one to run when you reach the reader. Go to the NFC settings and select the default app (usually Google Pay or HCE Wallet) under Touch and Pay.

It’s also worth checking if flight mode or power saving is on, which can limit the operation of communication modules.Rebooting the device often helps to reset temporary driver errors.

⚠️ Attention: If NFC stopped working after the firmware update, try resetting the network settings. This won't delete your personal data, but will return Bluetooth, Wi-Fi and other settings. NFC factory-value.

In rare cases, the problem lies in the hardware, whether the antenna inside the case is unstuck or the controller is out of order, and if the software methods do not help, and the service center confirms the presence of the chip, you may need repair.

💡

90% of NFC problems are solved by removing the security case or reinstalling Google Play Services updates.
