original passage: Consumer protections vary, depending on the network used. Visa and MasterCard, for instance, prohibit minimum and maximum purchase sizes, surcharges, and arbitrary security procedures on the part of merchants. Merchants are usually charged higher transaction fees for credit transactions, since debit network transactions are less likely to be fraudulent. This may lead them to "steer" customers to debit transactions. Consumers disputing charges may find it easier to do so with a credit card, since the money will not immediately leave their control. Fraudulent charges on a debit card can also cause problems with a checking account because the money is withdrawn immediately and may thus result in an overdraft or bounced checks. In some cases debit card-issuing banks will promptly refund any disputed charges until the matter can be settled, and in some jurisdictions the consumer liability for unauthorized charges is the same for both debit and credit cards.
