MM/YY: MM/YY refers to the expiration date of the debit card. MM stands for the two-digit month, and YY represents the two-digit year. The expiration date indicates the month and year until which the card is valid. After the expiration date, the card cannot be used for transactions, and a new card with a new expiration date needs to be issued.

The abbreviation MM/YY on a credit Card or debit card refers to the two digits of the month and the four digits of the year that determine the expiration date of the card, better known in bank or credit jargon as “expiration date”. We clarify that this corresponds to the card or plastic, not your account or line of credit.
