HOW IT WORKS_

Block repeated coupon and promo abuse with device intelligence

Detect repeated promo use, stop bonus fraud, and separate abuse from normal customer activity. Fingerprint uses 100+ device and browser signals to assign each visitor a unique visitor ID.

Block repeated promo redemptions to preserve revenue

Stop visitors from using the same coupon, promo, or bonus code more than once. Fingerprint assigns a unique visitor ID to each browser or device, so you can spot and block repeat redemptions — even if someone clears cookies or switches to incognito mode. This helps you keep your offers fair and your revenue protected.
