About CVVChecker

What we built

CVVChecker is a card verification tool built for people who need to know if a card is valid before processing it. Whether you're running an e-commerce store, testing payment flows as a developer, or working in risk and fraud — we built this so you don't have to guess.

How it works

You enter a card, pick a verification method, and within seconds you get a real result from the card network. We support two methods:

• Setup Intent — zero charge, completely invisible to the cardholder. Best for checking if a card is active.
• Auth Hold — a small hold that confirms the card has available funds. Voided immediately after.

Security first

Card data is tokenized in your browser and sent directly to the payment network — it never passes through our servers in raw form. We take data handling seriously and keep things minimal by design.

Who uses this

• Merchants dealing with chargebacks and fraud
• Developers integrating payment flows who need real test data
• Risk and compliance teams validating card information
• Businesses that accept prepaid or international cards
