Promo abuse and SMS fraud prevention for travel
Travel brands run first-booking discounts and welcome credits, and send booking and verification messages that cost money. FingerPrint Checker limits each offer per device and household, and caps how many messages one device can request.
Abuse patterns we see in this industry
- New-customer promo codes reused with new accounts.
- Referral and welcome credits farmed with many accounts.
- Forms that send a message per request, abused to run up SMS cost.
How FingerPrint Checker maps to them
- Coupon and referral abuse: one claim per device and household.
- SMS and OTP fraud: a per-device quota before each message.
- New account fraud: a decision before welcome credit is issued.
What it does not do
FingerPrint Checker is a device and household signal that decides whether one device may claim one thing. It is not identity verification, and it does not replace the checks your regulator or payment provider requires.
Frequently asked questions
Do guest checkouts work?
Yes. Quotas need no sign-in, and eligibility needs only an email, so guest checkout flows can be covered.
