Electronic Gaming Coupon Redemption With Cryptographic Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gaming systems consume significant paper resources through printed paper tickets and are prone to loss or misplacement, leading to potential financial loss for players.
Innovation Solution
Implementing electronic payment coupons secured with cryptographic keys associated with electronic gaming machines, allowing authentication and cancellation upon redemption to prevent counterfeiting and multiple redemptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If printed paper tickets are used for cash-out, then players can receive credit from EGM, but paper consumption increases and tickets may be misplaced causing financial loss
Solution Approach 1:
The patent replaces physical paper tickets with electronic payment coupons that contain the same functional information (credit amount, EGM identifier, barcode). The electronic coupon is stored on a portable device, eliminating the need for physical paper while maintaining the ticket's redeemability and information content.
Solution Approach 2:
The patent substitutes the mechanical paper-based ticket system with an electronic digital system. The physical paper ticket is replaced by an electronic data structure stored on a portable electronic device, and the mechanical act of printing and physically handing over tickets is replaced by electronic generation and transmission of coupon data.
2Ease of operation
If printed paper tickets are used for cash-out, then players can receive credit from EGM, but tickets may be misplaced resulting in financial loss
Solution Approach 1:
The patent replaces physical paper tickets with electronic payment coupons that contain the same functional information (credit amount, EGM identifier, barcode). The electronic coupon is stored on a portable device, eliminating the need for physical paper while maintaining the ticket's redeemability and information content.
Solution Approach 2:
The patent implements cryptographic authentication and cancellation mechanisms that prevent fraud before it can cause loss. The system verifies the authenticity of each coupon using cryptographic keys and automatically cancels redeemed coupons, preventing duplicate redemption or counterfeit tickets from causing financial loss.
3Reliability
If cryptographic keys are applied to electronic payment coupons, then authentication security is improved, but system complexity increases
Solution Approach 1:
The patent introduces a remote computing device as an intermediary that performs the cryptographic authentication of electronic payment coupons. This intermediary handles the complex verification processes, allowing the EGM and player devices to remain relatively simple while still achieving high security through the mediating authentication service.

AI summary
A cryptographic key is associated with an identifier (ID) of an electronic gaming machine (EGM). A computing device receives a coupon redemption request including an electronic payment coupon having the EGM ID and a credit amount. The computing device authenticates the electronic payment coupon based at least in part on the cryptographic key associated with the EGM ID and transmits a redemption confirmation when the electronic payment coupon is successfully authenticated. The computing device also stores a cancellation associated with the electronic payment coupon. The cancellation indicates that the electronic payment coupon has been redeemed for the credit amount. Such an electronic payment coupon may, for example, be generated by an EGM and/or be redeemed using an EGM and/or any other computing device capable of receiving the electronic payment coupon, transmitting a redemption request, and providing the credit amount to a user.
