PURPOSE:To attain an automatic restaurant system by supplying the eating data to an IC card containing a personal register number in an eating mode and then collecting en bloc the eating data of each person by an IC card reader/ writer at another time point. CONSTITUTION:A personal register number is stored previously in an IC card 1. Then each person puts his/her card 1 into an IC card reader/writer 6 set at each food counter to supply the food quantity data by himself/herself. Then the restaurant user puts the card 1 into another IC card reader/writer unified with a time recorder when he/she goes out of his/her office. Thus the eating data per day are collected for the corresponding user. |
