IMAGE OUTPUT SYSTEM, SERVER, IMAGE OUTPUT DEVICE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image output system for enabling a customer to conveniently and validly use a coupon, and for promoting the reuse of the customer.

SOLUTION: A user(customer) holds a portable telephone 107 or a receipt 109 on a two-dimensional code reader 309. A control part 501 of an image output device 105 transmits coupon data 327 read from the two-dimensional code reader 309 to a server 101 (step S21). A control part 201 of the server 101 collates coupon data 327 with customer information data 800 (step S22), and when they are matched (step S23: Yes), the image output device 105 performs image data processing (step S27).
