Gaming machine and coupons

摘要

A gaming machine (200) and game coupons (100) which allow an operator to redeem winning game coupons by inserting them directly into the gaming machine rather than by taking them to a cashier. The game coupons have machine-readable prize codes (114, 120) which represent a number of prize game credits. The gaming machine includes a bill validator (202) for accepting currency (244) and winning game coupons (248) from the operator. It also includes a code reader (224) for reading the coupon prize codes as the coupons are inserted. The gaming machine issues game credits to the player depending on the prize codes of the submitted game coupons. The gaming machine also incorporates a fraud prevention scheme. Each winning coupon is coded with a unique coupon identification code. The code reader records the coupon identification code of each winning coupon as it is submitted. Detected duplicate coupon identification codes are rejected.
