How should merchants handle card verification data?

Use verification fields only inside approved payment flows and never store CVV/CVC values after authorization. Tokenization and hosted payment fields can reduce exposure while supporting PCI compliance.

Why can card verification fail?

Verification can fail due to typos, mismatched billing details, expired cards, issuer rules, or conflicts between AVS and CVV settings. Review the gateway response code, then ask the customer to retry or use another approved payment method.
