If you haven't already, it may help to first learn about How a Secured Card Works here.
A secured card may come with a higher APR (Annual Percentage Rate) than an unsecured card, but it is up to the lender to decide what your APR would be based on your credit and other factors. Keep in mind that some secured cards may come with an annual fee in addition to the higher APR and a deposit. If you carry a balance, you would be charged interest.
To find more specific information regarding a credit card offer, you can click on the offer or where it says "see details, rates, and fees". If you're unable to find the information you're looking for, you may want to reach out to the lender directly.
