Create Account

Add FingerprintJS to your tech stack to prevent:

Coupon and promo abuse

Ensure your promotions are used fairly and not repeated or stacked to remove all profit from your sales.

Card Testing

Prevent fraudsters from using your site to test stolen credit cards through multiple small purchases.

Card Cracking

Stop malicious actors from testing combinations of expiry dates, postal codes, and CVVs with lists of purchased PANs.

Friendly Fraud

Sometimes a real user will dispute payments even though they received a product or service. Flag these users easily to prevent future chargebacks.

Stop chargebacks in their tracks

Any form of payment fraud can result in a chargeback for your website, which may result in lost revenue, stolen goods or services, and damage to your merchant reputation. No matter the cause, accurate user identification helps reduce this incredibly important indicator of fraudulent activity by authenticating or stopping at-risk purchases before they occur.
