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.
We use Chargebee to manage subscriptions and billing. Chargebee is a cloud-based service that is used around the world by many hundreds of companies that offer flexible subscriptions. It’s predominantly used by companies that provide software as a service. We’ve integrated our system with Chargebee as it helps us manage our systems effectively and gives our customers a user experience that is simple and effective. In order to process your payment, Chargebee will verify your card.
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.
