Sign-up bonus and referral abuse prevention for fintech
Fintech apps pay sign-up bonuses and referral rewards, and attract people who open many accounts to collect them. FingerPrint Checker gives your backend a device-level decision at the moment of the reward, including in iOS and Android apps.
Abuse patterns we see in this industry
- Bonus farming with many accounts on a few devices.
- Referral rings and self-referral.
- Scripts that call the app’s API directly.
How FingerPrint Checker maps to them
Treat the answer as one signal in your own risk process.
- New account fraud: a decision before the bonus is credited.
- Coupon and referral abuse: a relation check between inviter and invitee.
- Mobile app fraud: install identification and Play Integrity, App Attest and DeviceCheck proofs.
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
Is this KYC?
No. KYC verifies who a person is. FingerPrint Checker recognises a device and household. They answer different questions and can be used together.
