Abstract: A centralized system of accumulating cash value for consumers based upon point-of-sale transactions with multiple merchants is disclosed wherein for each transaction, the consumer's account number (such as the Social Security number) and birthdate are transmitted to a central system along with data identifying the merchant and a credit value for the transaction. The credit value may be based upon predetermined incentives associated with the transaction such as coupons, rebates or discounts, and/or upon a credit rate determined by the merchant applied to the amount of the transaction. At the central location, a cash value for that consumer is incremented by the credit value and a bill value for that merchant is similarly incremented. Periodically, the merchants are billed for the accumulated bill value or credited for any third party incentive amounts confirmed at the central location.
