The intelligent tray settlement desk uses RFID radio frequency technology to realize quick settlement, and its working principle is as follows:

After the tableware with a chip enters the magnetic field, it receives the special radio frequency signal sent by the reader, and then it can be sent out to the product information reader stored in the chip with the energy obtained by the induced current, and then the information is decoded, and the relevant data is processed and displayed on the display screen through settlement software.
