RFID radio frequency identification is a non-contact automatic identification technology, it automatically identifies the target object through the radio frequency signal and obtains relevant data, identification work without manual intervention, can work in a variety of harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, fast and easy to operate.

Card reading coil is also called card reading antenna. It is made of enamelled wire. This coil is made of directly soldable enameled wire, which can be tinned directly with electric soldering iron or welding table (such as common 936 welding table, temperature above 400 degrees) without removing paint. Very easy to use.

The inductance is 345uH±5%, the commonly used size is 50*70MM,40*60MM, and the circular diameter is 35MM

Power supply :5V, current :30MA

Operating frequency :125KHZ ±1Khz

Support card: Read-only card (cannot write) EM4001/4102 or compatible EM ID card

(125KHZ,64 split frequency, 64-bit Manchester coding)

Card reading distance :max 6CM distance depends on the shape of the card and the size of the antenna

Card reading mode: Read the card according to the command

Card reading speed :<250MS

Operating temperature :-10~75 ℃

After the module is powered on, it is in the waiting state for the command "Connect the power and antenna". After receiving the command to read the card, the module reads the card number of the corresponding card and then returns the data. When all the returned data is sent, the module enters the command waiting state and waits for the next card reading.

Module input and output is TTIL-RS232 ASCII data output (serial port output TTL level)9600 bps,n,8,1(baud rate 9600 no check bit data 8 bits 1 stop bit)(can also be output according to customer requirements)

AA01 BB Read the first route

AA02 BB Read the second route

AA03 BB read the third way

AA04 BB read the fourth way

AA05 BB read the fifth way

Reading card module returns data:

The data is AA+01+07+ antenna number + 5-byte card number +CHECKSUM+BB

CHECKSUM is the checksum of data
