How does a secured credit card work?
A secured credit card works almost identically to a regular credit card — you swipe it at stores, pay the balance monthly, and the issuer reports your payment history to the credit bureaus. The key difference is the security deposit. When you open the account, you put down a cash deposit — most commonly $200 to $500 — and that amount becomes your credit limit.
The deposit sits in an account and is returned to you when you close the card or graduate to an unsecured product. It is not applied to your monthly payments; you still owe whatever you charged. The deposit only comes into play if you default on the account.
For ITIN holders, secured cards are valuable because the deposit eliminates the issuer's exposure to your thin credit file — making approval far more accessible than unsecured products.
What features should you look for in a secured card?
Not all secured cards are created equal. Some carry high fees that effectively reduce your available credit. Before applying, compare these key features:
| Feature | What to look for | Red flag |
|---|---|---|
| Bureau reporting | Reports to all 3 bureaus (Equifax, Experian, TransUnion) | Reports to only 1 or none — won't build a full credit file |
| Annual fee | $0–$35/year | $75+ annual fee, or monthly "maintenance" fees |
| Minimum deposit | $200–$300 to start | Minimums over $500 that lock up large cash sums |
| Upgrade path | Clear criteria to graduate to unsecured card | No upgrade option — you'll have to apply elsewhere |
| Deposit flexibility | Can increase deposit to raise limit over time | Fixed limit with no increase option |
| ITIN acceptance | Explicitly accepts ITIN or foreign passport | Requires SSN only — verify before applying |
How do you use a secured card to build credit?
The card itself doesn't build credit — how you use it does. Payment history accounts for 35% of your FICO score, making it the single most important factor. Amounts owed — primarily your credit utilization ratio — is the second most important at 30%.
- Charge one or two small purchases each month — a grocery run or a streaming subscription. You want the card active and reporting positive payment data.
- Pay the full balance by the due date. Carrying a balance does not help your score and costs you interest. Always pay in full.
- Keep your balance below 30% of your limit — and ideally below 10%. On a $300 limit, that means keeping your balance under $90 when the statement closes.
- Never miss a payment. A single 30-day late payment can drop your score by 60–110 points and stays on your report for seven years. Set up autopay for the minimum as a safety net.
- Don't close the account early. Length of credit history (15% of FICO) benefits from accounts staying open. Even after you get an unsecured card, consider keeping the secured card open.
When can you graduate to an unsecured card?
Most issuers review secured accounts after 6–12 months. Graduation typically requires: no missed payments, a FICO score that has developed (usually 630+), and steady income. Some issuers do this automatically; others require a request. When you graduate, the card product changes to unsecured, your deposit is refunded, and you may receive a credit limit increase — all without a new hard inquiry.
If your issuer doesn't offer a graduation path, you can also open a new unsecured card once you have 12+ months of positive history, then keep the secured card open for the age-of-accounts benefit.
