The main advantage of the method is the connection speed (less than 1 second) and minimal battery consumption, since the energy is spent only on initializing the connection. The data exchange itself takes place via Wi-Fi Direct (for large files) or Bluetooth (for small ones), but the trigger is precisely the one that serves as the connection. NFC. This makes the technology ideal for transmitting contacts, photos or documents in environments where connection speed is important, such as meetings or transport.

However, the method has limitations: the maximum transfer speed is lower than that of a cable connection, and compatibility depends on the Xiaomi model and version. MIUI. In this article, we will discuss how to configure the transfer of files through NFC on different devices, what formats are supported, and what to do if the connection is not established.
