Why is the expiry date important for payment security?

An accurate expiry date helps confirm the card is still active and adds a layer of validation beyond the card number. It reduces the risk of using lost or cancelled cards.

What happens if the expiry date is incorrect?

The payment processor will usually return an error code, and the transaction will not go through. The customer should be asked to check the date and try again.
