The final cost of a purchase is determined when a credit card is accepted. Merchants preauthorize the card to ensure it doesn’t exceed the credit limit. A $1 charge when renting a car or staying at a hotel should disappear once the final purchase is reflected on the statement. However, if the charge remains or multiple charges appear, contact the bank. Generally, $1 charges are nothing to worry about, but unauthorized ones should be investigated.
