When you use your Central Maine Debit or Credit Card at an automated fuel dispenser (gas pump), the fuel dispenser merchant will try to authorize a hold up to $75.00 even if you are only planning to purchase $25.00 worth of fuel. This hold is then released. The $75.00 is then checked against the account for availability before an approval is made. You need to have $75.00 in your account to purchase fuel from an automated fuel dispenser. If you want to purchase more than $75.00 in fuel with your debit or credit card, you will need to stop at $75.00 and re-authorize for more. Some fuel merchants may only authorize $1.00 and release the hold.
