Rfid Smart Watch is equipped with a Bluetooth module, an RFID reader, a rechargeable battery and a GPRS module. The terminal has two working modes, which can not only read the wristband data through Bluetooth and upload it to the server, but also display the data in the server, and can also directly read the RFID chip information in the wristband and directly query after the identity authentication. The data in the bracelet in the server is faster than the Bluetooth mode.
