Tokenized Promotion Authorization at POS Without Coupon Handling

The patent replaces the mechanical system of physical coupons and graphic images with a digital token-based system. Tokens are transmitted electronically through communication interfaces between portable devices and point of sale terminals, eliminating the need for physical handling and visual verification of coupons. This substitution directly resolves the contradiction by improving ease of operation while reducing process complexity.

The patent creates digital copies of promotion credentials in the form of tokens that can be transmitted electronically. Instead of requiring original physical coupons or printed images, the system uses replicable digital token representations that convey the same promotional information. This copying approach enables convenient electronic transmission and processing, resolving the contradiction between ease of operation and process complexity.

The patent performs promotion identification and token validation as preliminary actions during the authorization request process. By integrating promotion checking into the existing authorization flow rather than adding separate steps, the system applies promotions transparently without significant time addition. This preliminary action approach resolves the contradiction by maintaining convenience while minimizing time loss.

The patent merges the promotion redemption process with the existing transaction authorization process. Instead of handling promotions as a separate step, the system combines promotion identification, token validation, and discount application within the same authorization request flow. This merging eliminates additional time requirements while preserving the convenience of automatic promotion application.
