Retailers are not responsible for the amount of the hold or the length of the hold when a customer conducts a signature debit transaction; both the amount and the length of the hold are determined by  the bank issuing the debit card.

• Both Visa and MasterCard require that retailers place "preauthorizations" of $1 on signature debit (check card)and credit card gas purchases. Once the transaction is preauthorized, the bank that issued the debit or credit card places a "hold" on that account. Most consumers don't notice holds on their credit cards because they have sufficient credit lines that they don't exceed, even with holds.
• Holds are not unique to gas purchases: they are standard practice for any business that accepts plastic as a form of payment in a situation where the final dollar amount to be assessed is unknown in advance. Holds placed on gas purchases are similar to the preauthorizations that hotels do with a credit card when someone checks in or with car rentals.
• Most holds today are between $50 to $100 to approximate the cost of a fill-up. The amount of the hold has increased as gas prices have increased; $35 was previously a common amount.
• Under all normal circumstances, it's not the retailer who is responsible for continuing the hold, since credit/debit card network rules make it impossible for the retailer to extend the hold.
• For signature-based debit transactions (such as using a check card as a credit card), holds, like the holds on credit cards that can affect someone's spending limit, can remain for 48-72 hours, since the processing times are slower. Generally, they should last a shorter period of time. Retailers conduct "batch" transactions at least daily; any time that the hold lasts beyond that time for signature-based debit is due to bank settlement processes.
