The NFC (Near Field Communication) module in Xiaomi Poco X3 smartphones offers opportunities for contactless payments, fast file transfer and smart device management. However, not all versions of this device are equipped with a chip, depending on the region and modification. In this article, we will learn how to check for NFC, activate it in settings and avoid typical errors in use.
It's important to understand that the Poco X3 came in a number of different versions: the standard model (without NFC) and the Poco X3 NFC version (codenamed surya). If your device supports the technology, you can use it for Google Pay, Mi Pay, tagging or pairing with speakers. But even with a chip, the feature can be hidden in the menu โ we'll show you where to look.
Before you go to setup, make sure your Poco X3 is updated to the latest version of MIUI. In older firmware, the NFC interface may have been different, and some features (such as card emulation) were limited, and check if the case or protective film is blocking the antenna, which is a common cause of payment failures.
