Have you noticed that your debit card has an expiration date on the front of the card? It's that little number with a slash printed on the front next to your name. But what do you do when your debit card expires?
Going back to cash mode can feel a bit uncomfortable too. Hence, getting the card renewed is the best thing to do to avoid all the hassles of cash payments.
Discard your old card as soon as you receive the new one. Even if the old card can't be used for transactions, the old cards still may get misused by scammers.
