Laundry cards Visa and Mastercard credit/debit/gift cards may be used as payment for each individual washer and dryer. You must have a minimum of $8.00 available on your debit/credit/gift card for 3 hours. After 3 hours, the $8.00 hold will be released and only the amount you used within the 3 hours will be charged to your account. If you do not have at least $8.00 available your transaction will be declined. You may use a pre-paid debit/credit/ gift card, but it must have a minimum of $8.00 available.
