Which of the following is true about store charge cards?

Store charge cards are indeed a form of revolving credit. This means that the user has a credit limit and can borrow money up to that limit repeatedly as long as they make the required payments on time. The outstanding balance can fluctuate—clients may carry a balance or pay it off in full each month.

Revolving credit allows for flexibility regarding payment amounts and borrowing, which differentiates it from installment loans that require fixed payments over a predetermined period. The ability to utilize the available credit repeatedly—as opposed to a one-time withdrawal—makes store charge cards a type of revolving credit.

In contrast, other aspects such as secured loans or collateral are not typically associated with store charge cards. These cards do not require collateral, meaning that they are unsecured and based on the user's creditworthiness. Additionally, store charge cards often come with interest rates, so the notion of them being interest-free is not universally applicable.
