NFC on Xiaomi Poco X3: How to enable, configure and use to the maximum

Xiaomi Poco X3 is one of the most popular mid-range smartphones, which, despite the budget cost, is equipped with an NFC module. However, many users face problems when trying to activate it: the feature can be hidden in settings, not work due to regional restrictions or require additional configuration. In this article, we will analyze all the ways to enable NFC on Poco X3, from basic to advanced, and also explain how to use the chip for payment, file transfer and automation of tasks.

It's important to understand that the Poco X3 came in a number of different versions (like the Poco X3 NFC and the Poco X3 Pro), and not all of them support contactless technology. If your model doesn't have a physical module, no manipulation of the settings will help. How do you check this? About this in the first section.

Check for NFC in your Poco X3

Before you try to turn on NFC, make sure your smartphone is equipped with it. In the Poco X3 lineup, only the Poco X3 NFC (codename surya) model has an integrated chip. The Poco X3 Pro (codename vayu) and the standard Poco X3 (no prefix NFC) are devoid of this feature.

Check the presence of the module can be in three ways:

• 📱 Through Settings: Go to Settings → Connections and sharing → NFC. If there is no point, there is no module.
• 🔍 Through specifications: enter in search IMEI Your phone (you can find it by command *#06#) on the IMEI.info website.

Why NFC can be hidden in the Poco X3 settings

Even if your Poco X3 NFC is equipped with a module, the menu item may not be available for several reasons:

1. Regional restrictions: Xiaomi often disables NFC in firmware for some countries (e.g. India or Russia in early versions of MIUI).
2. An outdated version MIUI. In the firmware below MIUI 12.0.3 support NFC mishandled.
3. Custom firmware: If you installed unofficial software (like LineageOS), the NFC drivers could be removed.
4. Hardware failure: damage to an antenna or chip (for example, after a phone falls).

To eliminate software problems, first update the system:

1. Go to Settings → About the phone → System update.
2. If a new version of MIUI is available, install it.
3. After the update, restart the phone and check for an NFC item.

2. Find NFC: Scroll the list to the Other Network Settings block – there should be an NFC switch.
3. Activate: Move the slider to the right. After activation, the "NFC is enabled" notification will appear in the status bar.

Once you have completed the command, restart your phone. To check for NFC status, use:

adb shell settings get global nfc_enabled

If the command returns 1, the module is activated.

💡
