Coupons ( 105 ) are encoded with an account identifier such as a credit or debit card number of the coupon issuer. The coupon may be a bar-coded coupon, or a coupon card, such as a magnetic stripe card or smart card. The bar-coded coupon may use a compact two-dimensional symbology such as Reduced Space Symbology (RSS) to carry the account identifier and other information such as enhanced consumer demographic data. Coupon information including the account identifier, a product or service identifier, and a discount identifier, are obtained from the coupon ( 105 ) at a point of sale location ( 100 ). The consumer is credited for the discount. The coupon information, including a merchant identifier are communicated to a processing center ( 135 ) using an existing credit card terminal ( 115 ) and communication protocol, such as ANSI X9, and processed like a conventional credit or debit card transaction.
