Why do we ask for the last 4 digits?
What does this do?
Used to tell your card apart in the list. The full card number is never requested or stored.
How to do it
- Enter the last 4 digits of your card.
- Select the expiry month and year together.
- Both are optional; you can leave them empty.
Why it matters
Telling your cards apart is all it is used for; CVV and PIN are never requested.
