What is card on file? How saved card payments work

Card on file means a customer's card is saved so they can be charged again without typing the details each time. It powers one-click checkout, subscriptions and account top-ups.

How it works

  • The customer pays once and agrees to their card being saved.
  • The card number is swapped for a token, so the real number isn't stored by the business.
  • Later payments use the token, either started by the customer or, with agreement, by the business.
  • The customer can remove the saved card or cancel at any time.

Customer and business-started payments

When the customer clicks to pay with a saved card, it's customer-initiated. When the business charges on an agreed schedule, like a monthly subscription, it's merchant-initiated. Card schemes have rules for both, including telling the customer clearly what they're agreeing to.

Keeping cards safe

Storing raw card numbers brings heavy PCI DSS duties, which is why most businesses rely on tokens held by their payment provider.
