PROBLEM TO BE SOLVED: To provide a game system which can check whether a holder of a storage medium is a game player himself/herself or not.SOLUTION: A card unit, at the time of discharging a visitor card, images a game player, and transmits the image captured at the discharging time and a card ID of the visitor card. A management computer 150 associates the image captured at the discharging time and the card ID with each other to store them. A prize exchange POS terminal 170, when receiving the visitor card (S 561), transmits the card ID (S 562). The management computer extracts the image captured at the discharging time which corresponds to the card ID (S 564) and transmits the extracted image captured at the discharging time (S 565). Since the prize exchange POS terminal displays the image captured at the discharging time (S 566), when the image captured at the discharging time is different from the holder of the visitor card (that is, when the holder of the visitor card is not the game player himself/herself), prize exchange is not performed. |
