Preauthorized Fuel Purchases
Many times, when you use your ATM/debit card to purchase gas, the gas station preauthorizes your account for a higher amount than the typical gas purchase to ensure that you have plenty of funds available for your gas purchase. Once you have pumped your gas, they then credit your account in the amount of their original preauthorization, and then debit your account for the amount of gas that you actually pumped. The preauthorization and subsequent credit transactions will disappear from your account in our nightly processing, so you will not see them on the following business day.
