Abstract: A web-based system and method are provided for electronic coupon fraud prevention. The system receives electronic coupon parameters from a coupon provider via a host website. Access is selectively providing to electronic coupons by members based on the parameters and member access criteria. The member selects coupons via the website which are then stored in a member account. Transaction data is received from a merchant point of sale, and the system determines which coupons may be available for use in the transaction based on the coupon parameters and the transaction data. A first set of coupon data is provided to the point of sale associated with electronic coupons which have been determined to be available, and a second set of electronic coupon data is received from the point of sale associated with electronic coupons which have been redeemed by the merchant in association with the financial transaction.
