Does the ATM/Debit Card Expire ?

Yesterday I got a new Visa ATM card for my Federal Bank Account. The expiry date is in 2017. The previous card was valid only for 3 years and the new one has a validity period of 10 years. I was told the old one will work without any problems. I tested and it indeed worked. I guess the bank auto renewed the old one and associated it with my account. Since the new one has a different card number, there’s no conflict of PINs.. However I just changed the new one’s PIN to the old one. So if you have a Federal bank account and thought that the card expired on expiry date, don’t worry, you an continue to use it.
