The power supply 1200 supplies power to the electromagnetic lock 200, the MCU control module 300 and the communication module 400 respectively via the power adapter 100. The communication module 400 is separated from the traditional wired connection mode, and the operation is more convenient. The RFID sensor 600 senses and reads the item information to ensure the accuracy of the data.
