What credit cards are and why the type matters
A credit card is a tool that lets you borrow money from a lender to pay for things now and repay later. The type of card you hold shapes what you pay, what rewards you earn, and what the lender expects from you. Banks and credit card companies offer different cards for different situations — some charge annual fees but offer travel perks, others charge nothing but give cash back, and some are built for people rebuilding credit after missed payments or defaults.
Understanding the main categories helps you match a card to your actual spending and financial situation rather than chasing rewards you will not use or paying fees that outweigh the benefits.
Key Takeaways
- Rewards cards offer cash back, points, or miles but typically charge annual fees and require good credit history to get approved.
- Secured cards require a cash deposit that acts as collateral and are designed for people with no credit history or poor credit scores.
- Balance transfer cards offer a low or zero interest rate for a set period, useful if you already carry debt on another card.
- Student cards have lower credit limits and fewer perks but are easier to get if you are enrolled in college and have limited credit history.
- Business cards work like personal cards but are tied to a business tax ID and often include higher spending limits and expense-tracking tools.
Rewards cards: cash back, points, and travel perks
Rewards cards return a percentage of what you spend back to you in the form of cash, points, or airline miles. A cash back card might give you 1.5% back on all purchases, or 3% on groceries and gas and 1% on everything else. Points-based cards let you accumulate points per dollar spent, then redeem them for gift cards, merchandise, or travel. Travel cards focus rewards on flights, hotels, and rental cars, and often include perks like airport lounge access or travel insurance.
The tradeoff is cost. Most rewards cards charge an annual fee ranging from $95 to $550 or more. You break even only if you spend enough to earn rewards that exceed the fee. A card with a $95 annual fee and 1.5% cash back needs you to spend about $6,300 per year just to cover the fee. Rewards cards also typically require a good credit score — usually 670 or higher — to get approved.
These cards work best if you pay off your balance in full each month. If you carry a balance and pay interest, the interest charges will quickly erase any rewards you earned.
Secured cards: building or rebuilding credit
A secured card requires you to put down a cash deposit, usually between $200 and $2,500, which becomes your credit limit. The card issuer holds this deposit as collateral. You use the card like any other — make purchases, receive a bill, and pay it. The deposit stays in a separate account and does not get spent.
Secured cards exist for two groups: people with no credit history (often young adults or recent immigrants) and people rebuilding credit after bankruptcy, defaults, or missed payments. Because the lender's risk is low — they hold your money — approval is much easier than with rewards cards. Most secured cards have no annual fee or a small one ($25 to $50).
The goal is to use the card responsibly for 6 to 18 months, then the issuer may upgrade you to a regular unsecured card and return your deposit. Some issuers do this automatically; others require you to request it. Check the card's terms before you explore to see whether the issuer has a clear path to graduation.
Balance transfer cards: moving existing debt
A balance transfer card offers a low interest rate — often 0% — for a set period (typically 6 to 21 months) on debt you move from another card. If you carry $5,000 on a card charging 18% interest, transferring that balance to a 0% card for 12 months saves you hundreds in interest, as long as you pay down the balance during that period.
Balance transfer cards usually charge a fee of 3% to 5% of the amount you transfer, paid upfront. A $5,000 transfer with a 3% fee costs $150. You also need good credit to get approved, typically a score of 670 or higher. After the promotional period ends, the interest rate jumps to the card's regular rate, often 15% to 25%.
These cards work only if you have a concrete plan to pay down the transferred balance before the promotional rate expires. If you transfer $5,000 at 0% for 12 months, you need to pay at least $417 per month to clear it. If you do not, you will owe interest on the remaining balance at the regular rate.
Student cards: lower limits and easier approval
Student cards are designed for people enrolled in college or university who have little or no credit history. They typically have lower credit limits (often $500 to $2,500), no annual fee, and modest rewards like 1% cash back or points on all purchases. Some offer bonus points for good grades.
The approval process is simpler than for rewards cards — you usually need to show proof of enrollment and a valid ID, not a credit score. This makes student cards a common first card for people building credit from scratch. The tradeoff is that the rewards are smaller and the credit limit is lower, so you cannot use the card for large purchases.
Student cards often convert to regular cards once you graduate or stop being a full-time student. The issuer may increase your credit limit and change the rewards structure at that point.
Business cards: for self-employed and small business owners
Business cards function like personal credit cards but are issued under a business tax ID (an EIN) rather than a personal Social Security number. They typically offer higher credit limits than personal cards, expense-tracking tools, and rewards tailored to business spending like office supplies, internet, or travel.
Business cards often have annual fees ($95 to $500 or more) and require good personal credit to get approved, since most issuers look at the owner's credit score even though the card is in the business name. Some business cards report to personal credit bureaus, affecting your personal credit score; others report only to business credit bureaus.
If you are self-employed or own a small business, a business card can help you separate business and personal spending for tax purposes. Keep in mind that you are personally liable for the card's balance — the business structure does not protect you if you default.
Store cards and co-branded cards
Store cards are issued by retailers (Target, Amazon, Walmart) and typically offer discounts or points when you shop at that store. Co-branded cards are issued by a bank in partnership with a brand — for example, a card branded with an airline or hotel chain that earns miles or points with that partner.
Store cards often have lower approval requirements than bank-issued cards, making them easier to get if your credit is fair or limited. However, they usually carry higher interest rates (18% to 25%) and smaller credit limits. The rewards are useful only if you shop at that store regularly.
Co-branded cards work best if you already use that airline or hotel chain frequently. If you fly once a year, the annual fee and limited rewards will not justify the cost.
Frequently Asked Questions
What credit score do I need to get a rewards card?
Most rewards cards require a credit score of 670 or higher, though some premium cards want 750 or above. If your score is lower, a secured card is usually the better starting point. You can explore for a rewards card later once you have built your credit history.
Can I use a secured card like a regular card?
Yes. You swipe it, make purchases, and pay a monthly bill just like any other card. The only difference is that your deposit sits in a separate account as collateral. The card issuer reports your payment history to credit bureaus, so responsible use builds your credit score.
Do I have to pay interest on a balance transfer card if I pay off the balance during the promotional period?
No. If you pay the full transferred balance before the promotional rate ends, you owe no interest on that amount. You will still owe the balance transfer fee (3% to 5%), which is charged upfront. Any new purchases you make on the card after the transfer may have a different interest rate.
What happens to my secured card deposit when I graduate to an unsecured card?
The issuer returns your deposit to your bank account, usually within 5 to 10 business days. Some issuers do this automatically after 6 to 18 months of on-time payments; others require you to request it. Check your card's terms to see which applies to your card.
Is a business card better for my credit score than a personal card?
It depends on whether the card reports to personal credit bureaus. Some business cards report to personal bureaus and help build your personal credit; others report only to business credit bureaus and do not affect your personal score. Ask the issuer before you explore if credit-building matters to you.
