So since nobody has yet answered this scenario -- maybe someone can clarify..
A. How do you check the balance on one of these cards? (ie Citi Visa Rebate Payment Debit card)
B. Does the card automatically deduct the remaining balance on the card from the purchase - or is this something you have to tell the cashier manually? (ie if I buy something for $100, do I swipe the card, it automatically deducts $40, then you pay the remainder -- or do I have to tell the cashier to deduct $40?)
C. If the above isn't automatic, what happens in a scenario where you over-charge the card?
Thanks
A. There usually is a phone number on the card you can call.
B. Simply tell the cashier you want to put $40 on the card, $30 in cash or whatever. Pretty much all businesses can take multiple forms of payment at any time and no one cares unless its something extreme like you have 10 cards or something.
C. It's like a normal debt card. don't have enough, the charge is declined.
