The RFID part is an ISO 14443A RFID reader/writer, It’s operating in the 13.56MHz 
ISM (Industrial Scientific Medicine) band for ISO 14443A RFID system. 
The circuit is comprised of a Micro Controller unit(MCU), 13.56MHz RF Transceiver 
circuit and a

LOOP Antenna. 

Micro Controller Unit(MCU) 
The Control circuit controls all of RFID ASIC signals. 
Control circuit outputs the command data which is needed to work the Transceiver 
circuit. When the response data from the RFID ASIC circuit, it will proceed 
recognition and other procedure. 
RF Transceiver circuit (RFID ASIC). 
The signal of 13.56MHz is supplied from crystal oscillator. 
The Magnetic field signal is generated by the Transceiver circuit. 
This ASK modulation signal is supplied through the Impedance transformer and the 
Antenna matching circuit to the external

LOOP Antenna.

 

The feedback signal sent from the tag is received at the

LOOP Antenna

 and is input to 

The H.P.F. The signal is demodulated by the RF ASIC . 

LOOP Antenna 

The external 

LOOP Antenna

 is formed with the coil, and supplies the electric power 

and the transmission signal to the tag by generating the flux of magnetic field

 

The product can only be installed in the device which the model name conforms to the 

following wildcard characters : AABBBXR-YY-ZZ , and it must be installed by professionals. The 

host end product must also pass the FCC Part 15 unintentional emission testing requirement 

and be properly authorized per FCC Part 15.
