What is NFC in Smartphones and How Does It Work?

NFC (Near Field Communication) is a short-range wireless technology (up to 10 cm) that allows devices to communicate without an internet connection. Unlike Bluetooth or Wi-Fi, NFC consumes minimal power and is activated almost instantly - just hold your smartphone to another device or tag.

In Xiaomi Redmi 9C (if the module is present), NFC operates at 13.56 MHz and supports three main modes:

• 📱 Active mode: both devices generate their own electromagnetic field (for example, when transferring files between smartphones).
• 💳 Passive mode: the smartphone reads data from a tag or card (payment, identification).
• 🔄 Emulation of the card: the phone itself acts as a contactless card (transport tickets, passes).

The main advantage of NFC is security, data is only transmitted at a minimum distance, and transactions are protected by cryptographic protocols, for example, when you pay through Google Pay, you create a one-time virtual card number that is useless for fraudsters.

⚠️ Attention: NFC In smartphones, it doesn't replace Bluetooth or Wi-Fi Direct for large files, the maximum data rate is only 424 Kbps, which is 100 times slower than modern Wi-Fi, but the power consumption is minimal: the module consumes only 15 mA in active mode.
