Which type of card requires full payment at the end of the billing period?

A charge card is the correct answer because it is designed specifically to require the cardholder to pay the full balance in full at the end of each billing cycle. Unlike credit cards, which allow users to carry a balance and make minimum payments over time, charge cards do not permit this. This characteristic encourages responsible spending habits and financial discipline, as users must ensure they have the funds available to settle their account at the end of the billing period.

In contrast, a debit card is linked to a checking account and allows users to withdraw funds directly from their account without incurring debt. A credit card enables users to borrow money up to a certain limit and often involves interest charges if the balance is not paid in full. A prepaid card is loaded with a specific amount of money in advance and does not involve credit at all, thereby not requiring any payment at the end of a billing cycle.
