Your deposit is $49, $99, or $200 depending on your creditworthiness, and you have 35 days after approval to fund it. Whatever you deposit, your starting credit line is at least $200, and Discover will assign a maximum line between $1,000 and $3,000 based on your creditworthiness, as of Sep 4, 2026. You can deposit more than the minimum before activating your card to raise your starting line. Earning works like Discover's flagship card: 5% back in categories that rotate each quarter, up to a quarterly maximum when you activate, then 1% on everything else. Discover does not publish the exact dollar cap for that quarterly maximum on the card page, so confirm it in your account once approved. The card carries a single published regular APR of 28.24% Variable as of Sep 4, 2026, with no promotional intro rate advertised. Build a track record of on time payments and Discover will refund your deposit and move you to the unsecured Discover it Cash Back Credit Card, same account number, same Cashback Match if you are still inside your first year.
