Principle of self-checkout system in cafeteria: RFID radio frequency technology of ISO/IEC 15693 standard is adopted, and RFID radio frequency chips are implanted at the bottom of each tableware. After the tableware enters the settlement area (RF antenna induction area), by reading and writing the RFID RF chip at the bottom of the tableware, the communication and management of the RFID RF chip at the bottom of the tableware are realized with the help of the computer and its communication technology, so as to realize rapid settlement.

The canteen self-checkout system is a machine that allows customers to check out in the canteen without the operation of employees. Used to replace the traditional canteen manual sales system. The canteen self-service settlement system has solved the problems of slow settlement, easy error, high cost and poor experience in traditional canteens, and has been widely used in dining places such as university canteens, canteens of enterprises and institutions, Chinese fast food chains and self-service hot pot restaurants.

Canteen self-service settlement system is a set of restaurant settlement system integrating RFID technology, which mainly provides fast settlement service for school canteens, restaurants of enterprises and institutions, fast food chain stores and so on. By implanting a radio frequency chip at the bottom of the dinner plate, quick settlement can be realized. Compared with the traditional settlement method, the canteen self-service settlement system has the characteristics of high speed, accurate accounting, good experience and unattended operation.

Self-checkout system is mainly composed of supporting tableware and self-checkout counter:

Self-service checkout counter: The self-service checkout counter adopts an integrated design, which integrates various devices such as radio frequency reading and writing equipment, card reader and display screen, and can quickly identify tableware entering the settlement area in batches (at most 15). Customers can check out and pay by self-service credit card, and the settlement speed can reach 2 seconds 1, without manual intervention at all, which greatly improves the settlement efficiency and alleviates the settlement queue congestion problem.

Matching tableware: At present, there are 24 styles, each with 25 colors, and 600 kinds of tableware with different colors or shapes. Different from ordinary melamine tableware, RFID radio frequency chip is implanted at the bottom of each tableware, which has self-service pricing function. Nevertheless, its daily use, cleaning and disinfection have passed the endurance test of high temperature, cleanliness and collision just like ordinary melamine tableware.
