Abstract

The invention relates to a supermarket payment system and method. The system comprises ultrahigh-frequency RFID electronic tags, an ultrahigh-frequency RFID reader-writer, a gravity sensing device, a local processor, a cloud server and a commodity settlement device. The method comprises the following steps of: reading all the commodities labelled with the ultrahigh-frequency RFID electronic tags on a cashier desk at once through the ultrahigh-frequency RFID reader-writer below the cashier desk; comparing a total commodity weight measured by the gravity sensing device and a total commodity weight calculated by the local processor and the cloud server; when the difference between the two total commodity weights is in a preset range, namely, when information of all the to-be-settled commodities is read, generating payment information to be displayed by the commodity settlement device, and completing payment by consumers through code scanning. According to the supermarket payment system and method, the queueing time of the consumers can be shortened, the supermarket cashier efficiency can be improved and the labor cost can be saved.
