RFID card reader module can read the EM4100 125K series (or compatible) RFID card. The module is very convenient to use, connected to the supporting read card antenna (coil) serial connecting one of the microcontroller, power supply is switched on. When RFID card into the card reader range module automatically to card through serial (UART) to send out, MCU receives can control relay to realize simple access.
