What is NFC?

What is NFC? NFC stands for Near Field Communication Technology, which is a non-contact identification and interconnection technology.

The difference between NFC and Bluetooth 5.0

1. Transmission distance

The transmission distance of Bluetooth 5.0 can reach 300m (theoretical), and the transmission distance of Bluetooth 4.0 can reach 50m (theoretical). The effective transmission distance of NFC is only 10cm.

2. Transmission rate

The Bluetooth transmission rate is 1Mbps, while NFC is 424Kbps.

3. Pairing

The Bluetooth connection needs to be searched and then paired, and the data can be transmitted only after the pairing is successful. NFC does not need to be paired, and can be automatically identified within the effective range, which is more efficient and safe.

How to choose

NFC is not better than Bluetooth, and Bluetooth does not have to be better than NFC, but has its own advantages in different uses. NFC is suitable for the exchange of important data, such as mobile payment, access control, and identification. Bluetooth is more widely used and is suitable for most short-distance data communications.

In fact, fast NFC can be used to guide the Bluetooth pairing process between two devices. Some headsets, speakers, game controllers and other devices will speed up Bluetooth pairing through NFC.
