What is the difference between debit/POS and credit transactions with my debit card?
When using your debit card, you have the option of doing at Debit/POS (Point of Sale) transaction or a Credit transaction. When you select a Debit/POS transaction, you are required to enter your PIN and have the option of receiving additional cash back. The funds are immediately debited from your account as they are when you make an ATM withdrawal.
