Gas stations, hotels, and car rental agencies often preauthorize transactions. This means they temporarily hold a specific amount of money in your account until the final payment amount is confirmed. This is a common practice to ensure that there are sufficient funds available to cover the transaction. Once the final payment amount is determined, the hold will be adjusted accordingly, and the remaining funds will be released back to your account. Please keep in mind that the duration of the hold may vary depending on the merchant’s policies.
