Credit cards are a modern convenience. And, increasingly, they’re a necessity. The growing list of businesses that accept only credit cards – and not cash — includes hotels, airlines, resorts, rental car companies and even some restaurants and merchants. But credit cards are more than just a transactional tool. Here’s what you should know about them.
How Do Credit Cards Work?
Credit cards are a payment method, yes, but they’re also a loan. More specifically, they’re a revolving line of credit. Every time you swipe, you’re using part of a pre-approved credit limit. Once you pay those transactions back, you’ll get the credit back, but you’re not required to cover all the charges each month. Instead, you’re expected to make at least a minimum payment (usually between 1% to 3% of the total outstanding balance) by each month’s statement due date. If you choose to carry a balance, you’ll pay interest — known here as your annual percentage rate, or APR.
How Do Credit Card APRs Work?
Well, it’s a bit complicated, to tell you the truth, but here’s the general idea. APRs are meant to give you an idea of how much revolving a balance on your credit card will cost you each year. But when it comes time to actually calculate interest, your issuer will use a daily periodic rate. The formula for the daily periodic rate (DPR) is your purchase APR divided by 365. That number gets multiplied by your average daily account balance and the number of days in your billing cycle. Your average daily account balance is most often a month’s daily balance divided by the number of days in that month. You can go here for a full explanation of credit card APRs.
Why Are Credit Cards Important?
Convenience isn’t the only reason credit cards are crucial. They’re the quickest and most-efficient way to build credit history. Using a card carefully and paying your bill on time without fail builds your credit score, which is increasingly necessary to rent an apartment, buy a home or purchase a car. Strong credit earns you lower rates on home loans, car loans and auto insurance. Employers check job applicants’ credit history, as do utilities and mobile phone companies.
Who Issues Credit Cards?
Credit cards are usually affiliated with one of four major payment issuers: MasterCard, Visa, Discover and American Express. MasterCard and Visa don’t issue cards, however; instead individual lenders (usually banks) do. That means that even if you can’t get one of these cards through one card issuer, another one may approve you. In other words, it pays to shop around for the right credit card.
What Types of Credit Cards Are There?
Credit cards come in all types. There are credit cards for borrowers with good credit, bad credit, or no credit at all. Certain cards are best for travel while others are better for gas rewards or business perks. Secured credit cards have low credit limits and require a security deposit, usually $200 to $500.

Reward cards let you earn points you can use to claim benefits. Purchases you make with the card help you build rewards which vary, depending on the card, from donations to causes of your choice, to cash back or points toward merchandise or discounts with airlines, hotels and resorts.
Your good credit earns you a much better selection, lower rates and low or no annual fees. With poor credit or no credit, your choices will include cards with higher interest rates, more fees and penalties.
How Do I Shop for a Credit Card?
How can you sort through all the options and decide which cards to apply for? That’s not difficult. You can avoid hassle and rejection by applying only for cards you’re likely to qualify for based on your credit profile. Here’s how:
