What is NFC and how does it work in Xiaomi smartphones

NFC (Near Field Communication is a short-range wireless communication technology (up to 10 cm) that allows you to exchange data between devices or read information from tags. NFC It is usually built into the upper body (near the camera) and operates at 13.56 MHz.

The main features of the technology:

• 🔄 Two-way communication: devices can both send and receive data (unlike the other devices). RFID, wherein the reader only receives).
• 🛡️ Safety: short range (maximum 10 cm) protects against accidental reading of data.
• ⚡ Low power consumption: the module has almost no effect on battery life.
• 📱 Compatibility: Works with most modern smartphones, bank cards and smart devices.

In Xiaomi smartphones NFC chip-based NXP (for example, PN547 or PN80T), which support all the basic standards: ISO 14443 (for bank cards), ISO 15693 (for tags) and FeliCa (popular in Japan) means your Xiaomi will be able to work with most contactless terminals around the world.

The technology uses induction communication: when two devices with a NFC-They're moving closer together, and they're sending an electromagnetic field between their antennas, and they're sending data through it, and the exchange rate is low, up to 424 kbps, but it's enough to send small amounts of information, like links or payment data.
