Electronic Tags For RFID Cards

It consists of a transceiver antenna, an AC/DC circuit, a demodulation circuit, a logic control circuit, a memory, and a modulation circuit.
(1) Transceiver antenna: Receives signals from the reader and sends the required data back to the reader.
(2) AC/DC circuit: Use the electromagnetic field energy emitted by the reader to provide stable power for other circuits through the output of the voltage stabilizing circuit.
(3) Demodulation circuit: Removes the carrier wave from the received signal and demodulates the original signal.
(4) Logic control circuit: Decodes the signal from the reader and sends back the signal according to the requirements of the reader.
(5) Memory: The location where the system operates and stores identification data.
(6) Modulation circuit: The data sent by the logic control circuit is loaded into the antenna and sent to the reader through the modulation circuit
