What is a plastic card issued by a bank for purchasing items via credit?

A plastic card issued by a bank for purchasing items via credit is known as a credit card. This type of card allows the cardholder to borrow funds from the bank up to a certain limit in order to make purchases. The amount spent on the credit card is typically paid back later, either in full or over time with interest. This financial instrument is widely used for its convenience, providing individuals with immediate access to funds without the need for immediate payment.

The key characteristic of a credit card is that it enables the user to incur debt which can be paid back later, generally on a monthly basis. When used wisely, credit cards can help build a positive credit history, which is crucial for larger financial decisions, such as obtaining a mortgage or auto loan.

In contrast, a debit card draws directly from the user's bank account, a charge card typically requires the balance to be paid in full each month without a grace period, and a cash card usually refers to a prepaid card that holds a specific cash balance. These distinctions clarify why the credit card is the appropriate choice for the question regarding a card used for purchasing items via credit.
