Abstract
A method is provided for coupon validation. A coupon is downloaded to a mobile device. The mobile device is used to determine a radio frequency fingerprint comprising cell tower data and cell sector data. The coupon is associated with the radio frequency fingerprint. Whether the radio frequency fingerprint matches a radio frequency fingerprint specified for redemption is determined. Redemption of the coupon is enabled in response to a determination that the radio frequency fingerprint matches the radio frequency fingerprint specified for redemption.
