2. Characteristics of 12 channel NFC12 communication technology:

(1) RF compatibility: ISO 14443, ISO 15693, Felica standards.

(2) Data transmission speed: 106kbit/s, 212 kbit/s, 424kbit/s.

(3) Wireless communication technology for close range (within 10cm) secure communication.

(4) RF frequency: 13.56MHz

Comparison between 3.12 NFC and Bluetooth

Firstly, the operating frequency of the 12 channel NFC is 13.56MHz, with a transmission speed of 424 Kbit/s, while the operating frequency of Bluetooth is 2.4GHz, with a transmission speed of up to 2.1 Mbit/s, with different transmission speeds and operating frequencies.

Second, the modes are different. The 12 way NFC communication mode can be one to many, while the Bluetooth communication mode can only be one to one.

Thirdly, the 12 channel NFC transmission distance is only 10cm, while the Bluetooth transmission distance can reach 10m. But the 12 channel NFC is slightly better than Bluetooth in terms of transmission power consumption and security, with different transmission distances.

The establishment time is different, and the Bluetooth communication setup program is relatively complex. The communication establishment time is relatively long, which takes about 6 seconds. The 12 channel NFC communication setup program is simple, and the communication establishment time is very short, only about 0.1 seconds
