5-way RFID card reader module parking lot multi-way ID card reader module attendance machine access control multi-way card reader

The card reading coil, also known as the card reading antenna, is made of enameled wire. This coil is made of enameled wire that can be directly welded. You can use a soldering iron or a soldering station without removing the paint (such as the common 936 soldering station, the temperature is above 400 degrees) ) directly tinned. It is very convenient to use. The inductance is 345uH±5%, and the commonly used size is 50*70MM.40*60MM.

working principle
After the module is powered on, it is in the state of waiting for the command (connect the power supply and antenna). When receiving the card reading command, the module will read the card number corresponding to a certain card reading line according to the command, and then return the data. When returning After all the data is sent, the module enters the waiting command state and waits for the next card reading. The input and output of the module are TTL-RS232 ASCII data output (serial port output, TTL level) 9600bps, n, 8, 1 (wave holding rate 9600 no Check digit data 8 bits 1 stop bit) (can also be output according to customer requirements)
