Stored cards checked against the networks in real time. Reissued or closed cards return fresh credentials.
Start using PayOS, pay per use. No sales call required.
One call at billing time. PayOS asks the networks whether the credential you hold is still the one the issuer stands behind.
Bulk updaters sweep your whole vault on a schedule, wasteful, stale by the time you bill. PayOS checks one card, in real time, exactly when it matters: just before you authorize.
Stale credentials fire these. When the credential is refreshed before the attempt, the decline never happens, and your standing with the networks stays clean.
One check in the payment path. That is the whole discipline, and it is what separates an approval from a decline you caused yourself.
