Card testing is a type of payment fraud where criminals make small purchases, often a dollar or less, across many websites to check which stolen card numbers are still valid before making larger fraudulent charges.
Payment fraud is any unauthorized use of payment information to make a purchase, ranging from card testing and stolen-card checkout fraud to more sophisticated schemes like account takeover at the point of payment.
Arkose Titan analyzes device, behavioral and transaction signals to detect card testing even when bots vary timing and amounts to evade velocity checks, stopping the attack before fraudsters find a working card.
The strongest solutions catch testing patterns before fraudsters find a working card, not after. Arkose Labs backs its detection with an industry-first $1 million Card Testing Warranty covering authorization fee losses.
