If the surface of a CSCS smartcard is worn away, how can I tell if the card has expired?

When you read a CSCS card using the smart technology embedded in it, the expiry date will be displayed on your screen.  Providing the date on your computer or mobile device is correct, if the card has expired or is about to expire, a warning message will flash on screen – orange if the card expires within the next 3 months, and red if the card has already expired.

Note: if the card is more than 6 months past its expiry date the cardholder’s details will not appear on screen.
