This is a standard practice with companies that accept gratuities (like taxi and limousine services) or where additional charges could be added to your final bill (like hotels and cruise lines).
To make sure that these amounts can be covered by your PayForward® Prepaid Visa® Debit Card, the business may add an additional percentage to the initial authorization amount. Once the transaction is settled, which may take a few days, any unused funds will be returned directly to your PayForward® Prepaid Visa® Debit Card.
Helpful tip: Purchases made at the gas pump temporarily add an authorization amount of $60.00 to cover large tank fill-ups. You can avoid this by paying the cashier inside for any amount up to your available PayForward® Prepaid Visa® Debit Card balance.
