Abstract: Embodiments include a system, method, and computer program product that authenticates a caller using calling party information. In an embodiment, an authentication device receives the call request and associated calling party information that includes a calling party number. The authentication device retrieves parameters associated with the calling party number, where a retrieved parameter is a number of accounts linked to the calling party number. The authentication device determines whether the number of accounts is between one and a threshold value, inclusive, and verifies that the call request originates from a location or a device associated with the calling party number. Based on the verifying and determining, the authentication device generates an authentication result that indicates whether the calling party number is authenticated.

Abstract: A gaming machine and game coupons are disclosed for allowing 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 are coded with a machine-readable prize code which represents a number of prize game credits. The gaming machine includes a bill validator for accepting currency and winning game coupons from an operator. It also includes a code reader for reading the coupon prize codes as the coupons are inserted into the bill validator. 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 to guard against fraudulently copied or duplicated winning coupons. Each winning coupon is coded with a unique coupon identification code. The code reader reads and records the coupon identification code of each winning coupon as it is submitted.
