The carrier device includes an encoded contract including a redemption condition relating to each coupon, wherein each redemption condition includes a specified range of dates during which its respective coupon may be redeemed. The customer presents the carrier device to a redemption party, who electronically reads the encoded contract and verifies whether the redemption condition is satisfied. If the redemption condition is satisfied, the coupon is updated to indicate that the coupon has been redeemed.
