What if the Visa Mini card doesn’t work in my model of card swipe reader?
If the card swipe reader can’t read the magnetic stripe on the Visa Mini card, ask the customer for the standard-sized Visa card issued with the Visa Mini. Then, swipe the standard-sized card through the card reader, and once the transaction is authorized, have the cardholder sign the printed receipt. If the customer doesn’t have the standard-sized Visa card, you may ask the customer for another form of payment.
