The Capital One Platinum Secured Credit Card may let some approved applicants open an account with a refundable deposit as low as $49, but that is not a universal offer. Capital One also lists $99 and $200 deposit tiers, and says the initial credit line will be at least $200 once the required deposit is paid. The card has a $0 annual fee on the issuer page checked October 7, 2026, but its listed purchase APR is 28.99% variable. It may suit someone seeking a way to establish or rebuild credit who can pay bills on time and avoid carrying a balance; it does not guarantee a score increase or a future unsecured card.
What the card costs and how much credit you may get
Capital One’s U.S. product page listed a $0 annual fee and a 28.99% variable purchase APR when checked October 7, 2026. These terms can change, so compare them with the current offer and your individualized disclosures before applying. The APR matters most if you carry a balance; paying the statement balance in full avoids purchase interest under the stated terms.
| Term | What Capital One lists |
|---|---|
| Annual fee | $0 on the issuer’s product page checked October 7, 2026. Capital One product page |
| Purchase APR | 28.99% variable on the issuer’s product page checked October 7, 2026; verify the rate in your current offer. Capital One product page |
| Minimum refundable deposit | $49, $99, or $200, depending on the offer for an approved applicant. The $49 tier is not guaranteed to every applicant. Capital One product page |
| Initial credit line | At least $200 after the required deposit is made, subject to approval and the offer. Capital One says an additional deposit may raise the initial line up to $1,000 under its stated conditions. Capital One product page |
The deposit and credit line are related, but they are not necessarily the same amount. A $49 or $99 minimum deposit can accompany an initial line of at least $200 if that is the offer made to the approved applicant. Capital One determines the required deposit; do not assume that choosing a smaller deposit tier or paying a particular amount will produce a specific limit.
How the security deposit and funding work
The deposit is refundable collateral securing the account, not a fee and not money applied to purchases or monthly bills. Capital One’s help center describes a secured card as a credit card account that requires a refundable security deposit to open and otherwise works like a credit card when making purchases.

Because the deposit does not pay the statement, you still need to make at least the required minimum payment each month. Paying the statement balance in full avoids purchase interest under the card’s stated terms; carrying a balance can incur the listed variable APR.

Can this card help build credit?
Capital One says it regularly reports account status to the three major credit bureaus. On-time payments and careful use may help establish or rebuild credit, but reporting does not promise a score increase, a particular credit result, or approval for another account. Capital One secured-card guidance
For the card to support a healthier credit history, use it within a budget and pay at least the minimum on time. If you can, pay the statement balance in full to avoid purchase interest. The security deposit does not remove the obligation to repay charges.

The issuer does not promise a fixed review date or upgrade timetable. Capital One: Upgrading or changing your card

Quick Recap
Best Value
- ONE CARD PROTECTS YOUR WHOLE WALLET: Drop a single KF-Premium card into your wallet, purse, or card holder and every card sitting near it is shielded from contactless RFID and NFC scans, so you do not need a separate sleeve on each card. This 2-pack covers a second wallet, a passport holder, or a family member.
- ULTRA THIN AT 0.9MM, BARELY THERE: Each blocking card is only 0.9mm thick, about as slim as one of your bank cards, so it slides into any wallet slot without the bulk of foil sleeves or switching to a new wallet. Slim enough that you forget it is working.
- STOPS FRAUD BEFORE IT STARTS: The armoured shield design sends out an interfering counter-signal that blocks unauthorized RFID and NFC readers from skimming your debit cards, credit cards, and IDs. It guards against contactless payment fraud, identity theft, and digital pickpocketing in crowds, on transit, and while you travel.
- WORKS THE MOMENT IT IS IN YOUR WALLET: No batteries, no charging, no app, and nothing to switch on. Protection is automatic and continuous for the life of the card, and the durable, high-quality build holds up to daily wear in a back pocket or bag.
- A PRACTICAL GIFT THEY WILL ACTUALLY USE: The sleek black finish gives it a premium look that suits travelers, students, parents, and anyone who carries contactless cards. Boxed as a 2-pack, it works for birthdays, holidays, or a stocking filler that quietly protects the people you care about.
Who should consider the Capital One Platinum Secured card?
- Potential fit: An approved applicant who wants a secured credit card, can provide the required refundable deposit, and expects to pay statements on time.
- Not a fit if: You need a guaranteed $49 deposit, a guaranteed credit-score result, a guaranteed upgrade date, or a card you can use without making monthly payments.
- Before applying: Confirm the deposit tier, credit line, APR, funding deadline, and full fee terms in the offer and agreement presented to you.
