Card expiration date

Card payments require an expiration date unless the customer creates a card token.

The expiration date is validated through the following steps:

• The expiration date field values are used, excluding any non-numeric characters.

• The values are interpreted in a four‑digit format: a two‑digit month and a two‑digit year (MMYY).

The cardholder should enter two-digit year (YY) that is greater than or equal to the current year and two-digit month (MM) that is greater than or equal to the current month.
