Yes. The expiration date can be found near the bottom of the front of the card. Typically, debit cards expire every two to three years, and if you still have an account with the bank, you will be issued a new one with a new expiration date.
Generally, a card can be used through the last day of the month in which it expires. For example, a card with an expiration date of 05/2014 would be good through May 31st, 2014.
