CHECKOUT APPARATUS, CHECKOUT SYSTEM, AND METHOD FOR PROMOTING USAGE OF SELF-SERVICE REGISTER

摘要

A self-service checkout apparatus includes a display device, a scanner configured to read identification information of a commodity, and a processor. The processor is programed by a registration processing program to: identify each commodity based on the identification information read by the scanner, and as identification information of each of multiple commodities is consecutively read by the scanner, determine each time the identification information is consecutively read, an interval elapsed since a last read of the identification information. The processor is further programmed to calculate a score based on the determined intervals, and control the display device to display the calculated score.
