that the card is legitimate and that the customer has funds available. When the transaction is settled, it will actually post for the value of the purchase. There currently is litigation in the State of Florida that alleges that some gas stations do not adequately inform their customers that a certain fixed dollar amount (usually between $75 and $100) will be requested as a pre-authorization in connection with a customer's purchase of self-service gasoline at the pump using a debit card and that this practice violates various Florida consumer protection and civil laws. The lawsuit was filed by Florida attorneys Cameron Moyer and James Staack in November, 2007. Class certification was granted by the Circuit Court in February, 2009. The defendant is currently appealing the Class Certification Order. Another example can be seen with a restaurant transaction. If an individual spends $40 at a meal, the server does not know how large a tip they will leave if they choose to leave one on the card. The restaurant's credit card terminal is typically set to authorize a larger amount, such as 20% above the cost of the meal, but the transaction will settle for the actual total including the actual tip written on the receipt. Some restaurants will authorize just the amount of the bill, but the transaction will settle higher with the tip included. This type of settlement (for an amount higher than the authorized amount) is only possible when the original authorization was executed with a specific merchant category code (hospitality). It is not possible in eCommerce or retail environments. Acquiring banks sometimes forbid the practice of preauthorizing an amount including a tip, but will guarantee settlement of the amount authorized, plus 15 or 20%. Other businesses that may settle transactions for different amounts than those originally authorized include hotels and car rental agencies. The final cost of these transactions can be extremely unpredictable from unforeseen extras such as room service charges, refuelling charges, or longer stays. Those companies typically place a hold on the customer's credit card at the beginning of the transaction for the estimated total, plus a percentage or a fixed cash amount (such as the estimated rental charges, plus 15% or $250). The establishments usually do not settle the transactions until after the customer has checked out or returned the rental car. Some hotels and car rental agencies do not accept Visa or MasterCard-branded
