A method and system for coupon distribution and use. A merchant provisions
a coupon with a coupon server, and the coupon server delivers the coupon
to a consumer's device via SMS, WAP push, e-mail, instant messaging, or
in another manner. The consumer then presents the device to a merchant at
a point of purchase, to convey the coupon from the consumer's device to
the merchant for validation and redemption with respect to a sales
transaction between the consumer and the merchant. The coupon can be
conveyed from the consumer's device to the merchant in various ways, such
as via radio frequency transmission or reading of the coupon from a
display of the device.
