SALE PROCESSING TERMINAL CONTROL SYSTEM

摘要

The sale promoting effect is improved by, especially, enhancing the fun of lottery drawn by customers when goods are sold or a service is provided. A register conducts processings of the sale of a commodity that a customer purchases or of a service that is provided to a customer and processings of lottery parallel. A register controller integrally controls the processings of lottery conducted by one or more registers. One of the controls conducted by the register controller is to acquire information on the history of the number of lottery processings from a register, to determine lottery patterns (winning probability, discount rate, etc.) according to the history information, and to update the lottery pattern data in the registers. Thus, the register controller can optimize the lottery patterns recorded in the registers to the ones of the largest number of lottery processings, that is, the ones having the best sale promoting effect.
