Different RFID frequency has different work principle
RFID frequency is not only decide to the RFID system work principle,RFID read range, and also decide to the easy and difficult of RFID tag and RFID reader. And don’t forget to consider the cost of RFID device. There is some clear how to use RFID frequency for vairous of RFID applications. That is ISM band. The typical RFID freqency : 125kHz, 133kHz, 27.12MHz, 433MHz, 902-928MHz,2.45GH, 5.8GHz and so on. As the working RFID frequency different requirments, RFID tags can be with Low Frequency (LF), High Frequeny [...]
