Discover says your refundable security deposit sets the credit line on the account, starting at $200. The deposit is held as collateral rather than used like prepaid spending money. You still use the card like a regular credit card and make monthly payments.

Discover says automatic monthly reviews start in your seventh month as a customer. To qualify for a deposit refund and possible upgrade, you need six consecutive on-time billing cycles and good status across all credit accounts you are responsible for.

Yes. Discover says the card earns 2% cash back at gas stations and restaurants on up to $1,000 in combined purchases each quarter, then 1% on other purchases. That gives it more everyday value than most secured cards.

It can help when you use the account responsibly and the issuer reports your activity to the major credit bureaus. Improvement depends on consistent payment behavior, manageable balances, and the rest of your credit profile.

Check the current deposit terms, rewards details, APR, account review rules, and any limits around getting the deposit back. Confirm the card fits your budget because carrying a balance can work against credit building.

A secured credit card gives you a revolving credit line that you borrow against and repay each month, while a prepaid card only lets you spend money you already loaded. With a secured card the deposit may be refunded later.

Make small purchases you can repay on time, keep balances well below the limit, and avoid carrying unnecessary debt. Those habits support cleaner payment history and lower utilization.

No. Approval is never guaranteed and score gains are not automatic. A secured card may be more accessible than some unsecured options, but results still depend on your credit profile and how you manage the account afterward.
