What Is an Unsecured Credit Card?
Quick Answer
An unsecured credit card is the most common type of credit card and doesn’t require a security deposit as collateral.

Credit cards come in two basic types: secured and unsecured. An unsecured credit card is simply one that doesn't require a security deposit as collateral. It's the most common type of credit card, and if you use a credit card, it's likely unsecured.
A secured credit card, on the other hand, requires you to provide a refundable security deposit to the card issuer when you open the account. Without this deposit, unsecured cards can be harder to qualify for, but they often come with greater rewards and more perks. Here's what you need to know.
How Does an Unsecured Credit Card Work?
Unsecured credit cards are revolving credit accounts that don't require any collateral. When you apply for an unsecured card, the issuer reviews your credit report, credit score and your financial details, such as your income and monthly expenses. These factors are used to help the card provider determine whether you qualify, your credit limit and your interest rate.
Once approved, you can make purchases up to your credit limit. As you pay down your balance, that credit becomes available again. You can borrow against your limit repeatedly without reapplying for credit.
At the end of your monthly billing cycle, the issuer sends you a statement showing all your transactions, the statement balance and the minimum amount due. If you pay your entire statement balance by the due date, you won't owe any interest. But if you carry, or "revolve," a balance to the next month, that unpaid amount will start accruing interest daily. Any new purchases you make will also accrue interest until you pay them off.
