What is Card Verification
Card verification is the process of validating a card to ensure that the card number provided is tied to a valid bank account, can be charged, and can be vaulted.
How it Works
Chargebee carries out card verification by performing a one unit charge (1 USD, 1 GBP, 1 AUD, 1 EUR, etc.) which is voided as soon as the authorisation is complete or fails.
