A card is a small, rectangular piece of plastic or metal that lets you make purchases. Whether you’re buying lunch or a new piece of furniture, a credit card enables you to borrow funds from a credit issuer to pay the merchant. Then, every month, you’ll receive a statement in the mail with your balance, which you’ll want to pay off every billing cycle. Otherwise, you’ll owe interest on the remaining amount.

While the concept sounds simple, it’s easy to rack up debt if you’re not careful. With that in mind, here’s credit cards explained in-depth.

Credit Card Meaning

Banks and other financial institutions issue credit cards to consumers to extend revolving lines of credit. A revolving line of credit means the cardholder can borrow money up to their credit limit and then repay it on a continuing basis.

With other lines of credit, like a personal loan, you take out a lump sum amount and agree to repay it within a specific timeframe. During this timeframe, you make fixed installment payments. Whereas with a credit card, you can repeatedly borrow against the limit, which gives you more flexibility to use the card as needed.

When you receive your credit card, you’ll note several different numbers on it. There’s the credit card account number, alongside your name and the credit card issuer’s logo. Also on a credit card are the credit card expiration date, which marks when the card is valid through, and the CVV number on a credit card, which offers an extra layer of security in purchases made online or over the phone.

How Does a Credit Card Work?

Once you have a new credit card in hand, you can use it to make purchases at places that accept credit card payments. Then, every month, you’ll receive a statement either electronically or in the mail, depending on your preference. The statement will include all purchases, your outstanding balance, and the minimum monthly payment due.

You’re required to make at least the minimum payment on your account to keep it open and in good standing. However, you also can opt to pay your entire balance in full or decide on another amount (as long as it meets the minimum payment requirement). If you were to pay an amount that exceeds your total balance, then you’d end up with a negative balance on your credit card.

If you aren’t able to make the minimum credit card payment, the outstanding balance will roll over to the next month and begin accruing interest and fees — which can significantly add up over time. Therefore, it’s best to get in the habit of paying off your credit card every month to avoid paying an exorbitant amount of interest. But, if your finances don’t allow you to pay the entire balance, you could make smaller payments throughout the month to minimize the amount of accumulating interest.

To ensure you make your monthly payments, you can usually set up auto-pay for the minimum payment. This way, you won’t miss a payment and get charged a late fee. Unfortunately, late payments also can end up on your credit report, which can negatively affect your credit score.

How Does Credit Card Interest Work?

Every credit card comes with an annual percentage rate (APR), which represents the annualized cost of borrowing including interest and fees and marks an important part of how credit cards work.

Some credit cards have more than one APR, such as a balance transfer APR, an introductory APR, or a cash advance APR. While introductory APRs are usually lower than the standard rate but only last for a promotional period, cash advance APRs are typically higher than the standard purchase APR.

You will pay interest based on the APR on a credit card if you have an outstanding balance that carries over from one month to the next. Credit issuers use your average daily balance, interest rate, and the number of days in the billing cycle to calculate the interest amount.

Usually, credit issuers offer a grace period where interest will not accrue. This period is typically between the statement date and due date, commonly 21 days.

Credit vs. Debit Cards

They may look alike, but there are notable and important differences between credit cards and debit cards. For starters, you’re not borrowing funds with a debit card. Instead, you’re drawing on funds in the bank account attached to the debit card. As such, you can’t incur interest charges, nor can you rack up debt. However, you can’t use a debit card to help establish your credit.

In general, debit cards offer less robust consumer protections against fraud in theft than credit cards do. They also don’t typically offer rewards or other benefits that credit cards can have.

6 Common Types of Credit Cards

Now that you understand how credit cards work, here are some available credit card options.

1. Reward Cards

You can earn cashback, points, or even miles when you spend money using a rewards credit card. Some credit cards may also offer a sign-up bonus. For example, a credit card could offer 100,000 points when you spend $4,000 or more within the first three months of enrolling.

You can usually find a card offering rewards that coincides with your spending habits. For example, if you love shopping at a particular store, retail-branded cards have lucrative benefits for frequent shoppers.

Keep in mind that you typically have to have a good credit score to qualify for a rewards credit card. But, even if you do qualify, it’s essential to keep your spending habits in check. Reward cards incentivize you to spend money, so you don’t want to end up overspending and getting into a pile of debt you can’t climb out of.

2. Credit Builder Cards

If you have little to no credit or need to build your credit back up, a credit builder credit card is a viable solution. You’ll likely start with a lower credit card limit and an APR that’s higher than the average credit card interest rate to reduce the credit card issuer’s risk.

Credit builder credit cards usually don’t come with the bells and whistles that rewards cards offer. Instead, the card can help you build your credit. With that said, you’ll want to use your credit card responsibly, making on-time monthly payments and paying off your balance every month. Not doing so could negatively impact your credit history and cost you a lot of money.

3. Balance Transfer Cards

Do you have a high-interest outstanding credit card balance? Using a balance transfer credit card is one solution for helping you tackle your debt. Balance transfer credit cards let you move your current credit card debt to a new account with a lower interest rate. Additionally, transferring your balance means you’ll only have to stay on top of one payment a month, rather than multiple.

Having a good credit score can help you qualify for a balance transfer credit card. If you qualify, you could receive a lower ongoing rate or even a 0% introductory rate, which usually will last for six to 18 months. You’ll want to try to pay off your balance within that promotional period, before the higher APR kicks in.

Note that balance credit cards often charge a fee for transferring a balance — usually 3% to 5% of the amount transferred. So, make sure you factor in the additional fees before you move over your existing balance.

4. Secured Credit Cards

Another option for those with little to no credit or poor credit history is a secured credit card. With a secured credit card, you make a refundable deposit, which protects the card issuer from defaulted payments. If you default, the credit card issuer can use the deposit to recoup the loss.

Your deposit is usually the amount of your credit limit. For example, if you are approved for a $500 limit, you may need to put down $500. Though your deposit will be tied up while the account is open, a secured credit card can allow you to build your credit when used responsibly. Just keep in mind that while secured credit cards are generally easier to qualify for, they also tend to have higher APRs and fees.

If you decide to close a secured credit card account, you can usually get your deposit back. The card issuer may also give you the option to upgrade to an unsecured card if you’ve proven your creditworthiness. In this case, you’d receive a refund as well.

5. Travel Credit Cards

If you’re a frequent flier or visit hotels often, a travel credit card can be a lucrative choice. Many airline and hotel brands have credit cards that let you earn miles, points, or rewards to use toward your travel adventures. Some credit cards may also come with a sign-up bonus or extra perks such as free checked bags, access to VIP lounges, and travel insurance.

When selecting a card, you’ll want to find the card that makes sense for the way you travel. That way, you can get the most out of your credit card. Travel credit cards usually require applicants to have good to excellent credit for approval. So, before applying, make sure to check your credit score to see if it’s acceptable.

6. 0% Introductory APR Credit Cards

If you’re getting ready to make a big purchase, a 0% introductory APR credit card might be worth considering. With this type of credit card, the card issuer gives you a 0% introductory rate to make purchases during a specific time frame. This way, you can make the purchase without paying interest on the expensive item(s).

However, you’ll want to make sure you repay the entire amount before the introductory period ends to avoid interest. Before you swipe, make sure you have a plan to pay off the balance within that time frame.

Also note that to qualify for a 0% introductory APR credit card, you usually must have good to excellent credit.

Pros and Cons of Credit Cards

Here’s an overview of the pros and cons of credit cards, which are helpful for anyone just getting familiar with the credit card definition to be aware of:

Pros

Reasons a credit card can be worthwhile include:

•   Convenience. A credit card offers much greater convenience than, say, carrying around a wad of cash. You can easily swipe or tap your card at any merchant that accepts credit card payments, which the vast majority do.

•   Pay over time. Another benefit of a credit card is that it allows you to pay over time for a purchase. Say you’re in an emergency and need to access funds immediately, but know you’ll be good to pay back the amount soon. Or maybe you’re making a big purchase and don’t want to have to shell out for it all at once, instead spreading out payments throughout the month.

•   Build positive credit history. Credit cards give you the means to establish a strong payment history, which can help boost your credit score. When you need to apply for a personal loan or mortgage in the future, a higher credit score can help you qualify for better terms and rates.

•   Track spending. Credit cards are valuable tools for budgeting since many cards let you track your spending on an app or online. Also, some credit cards give you the ability to categorize your expenses to see where your money is going and make adjustments accordingly.

•   Get fraud protection. If your debit card information is stolen, fraudsters can directly access your bank account. But, if you use a credit card, you usually have more fraud protection benefits in places such as purchase protection and identity theft protection. For instance, you can dispute a credit card charge and even receive a credit card chargeback.

•   Earn rewards. Many credit cards offer a reward program that gives you points or cashback when spending money. For example, you could earn money for traveling, shopping, or even statement credits.

Cons

Remember, while credit cards are a valuable financial tool, they can also hinder you if not used responsibly. Here are some downsides to keep in mind:

•   Potential to damage credit. Just as you can boost your score with a credit card, you can also damage it.

•   Possible to rack up debt. Credit cards can make it easy to rack up a mountain of debt that can continue ballooning, thanks to interest. It’s not easy to get rid of credit card debt either (for instance, here’s what happens to credit card debt when you die).

•   Interest. Credit cards generally have higher APRs compared to other types of debt — usually well into the double digits. It can make purchases much more expensive if you’re paying a hefty amount of interest on top of the actual cost.

•   Fees. Another downside of credit cards is the potential to incur fees. Some are avoidable, like late fees or cash advance fees, while others can be harder to avoid, such as if your credit card of choice charges an annual fee.

How to Apply for a Credit Card

Before you apply for a new credit card, you’ll want to check your credit score. You can pull a free copy of your credit report at AnnualCreditReport.com. Knowing your credit score will help you determine whether you meet the approval requirements for the cards you’re interested in.

Once you decide on some card options, you can usually get prequalified online. If you prequalify for a card, your approval odds could be in your favor (though you’re still not actually approved). Also, when companies process your preapproval, they only complete a soft credit inquiry, which won’t impact your credit like a hard inquiry does. However, when you’re ready to apply, the credit issuer will conduct a hard credit inquiry.

If you’re approved for the card you apply for, you should receive your credit card in the mail within 14 days.

The Takeaway

A credit card, in simplest terms, is a physical card you can use to make purchases and pay bills. A credit card typically comes with a credit limit, or the maximum amount of money that the credit card company allows you to borrow.

You’ll receive a statement each month that details the purchases you made, the total outstanding balance, and also the minimum payment due. You’re required to pay the minimum amount due each month in order to remain in good standing with the credit card issuer and avoid harming your credit score. Paying off your balance in full each month enables you to avoid interest charges.

Before you apply for a credit card, it’s important to research your options to understand which card may be best for your current situation and financial needs.

FAQ

What are the main differences between credit and debit cards?

Debit cards use the money in your checking account to pay for purchases. When you make a purchase using a credit card, on the other hand, you’re using a line of credit to borrow money. Therefore, you usually have to pay interest on your transactions with a credit card if you don’t repay your balance right away.

How do I choose a credit card?

It’s helpful to select a credit card that matches your needs and financial habits. You’ll also want to make sure you meet the card issuer’s approval criteria. For example, if a credit card requires a credit score of 700 and your score is 650, you may have to explore other options or take steps to improve your credit before applying.

How long does it take to get a credit card?

Once you submit a credit card application, it may take just minutes before you’re approved. Usually, you’ll receive your credit card within 14 days of approval. You can call the credit issuer and request expedited processing if you need your credit card sooner.

A credit card can be a useful tool for managing your money. But before tapping into the benefits, the first thing to know is how to get a credit card. There are some requirements, and some tips that can help when it comes to getting approved.

Here’s the lowdown on the key things to know to apply for a credit card — and most importantly, to get approved for a credit card.

What to Consider When Applying for a Credit Card

Before you worry about how to get a credit card, it’s helpful to first understand what a credit card is. As the first word in its name suggests, a credit card is a line of credit, which is a type of flexible loan that enables you to borrow money up to a fixed limit.

When an individual charges a transaction at a business that accepts credit card payments, the credit card company pays the merchant. The cardholder must then pay back the credit card company by a designated date. Otherwise, they’ll incur interest charges.

This basic premise of how credit cards work means the card company is taking a risk when extending credit to any individual. They assess that risk via an application that determines not only whether the individual gets approved for a credit card, but also factors like their credit card limit and annual percentage rate (APR) on a credit card.

Before applying, there are some important considerations that can help improve your chances of getting approved for a credit card.

Learn About the Terms Associated with Your Credit Card

Evaluating different credit cards can feel overwhelming for a newbie, so it’s a good idea to get familiar with some basic credit card terms that are common across all credit cards. Here are some common terms you might run into in a credit card application and as you begin to use your new card:

•   Balance: Your balance is the amount of money you owe on your credit card. This can include purchases (even paying taxes with credit card) as well as any fees, balance transfers, and cash advances.

•   Balance transfer: A balance transfer is when you move money from one credit card to another credit card, ideally one with a lower APR. This can allow you to pay off your debt more easily, though you’ll often pay a balance transfer fee to move over the balance.

•   Billing cycle: A credit card billing cycle is the period of time between the regular statements you receive from your credit card company. Usually, billing cycles occur on a monthly basis.

•   CVV: The card verification value, or CVV number on a credit card, is a three- to four-digit number that appears on a physical credit card. It serves as an additional layer of security in transactions that occur over the phone or online.

•   Expiration date: A credit card expiration date represents when a credit card is valid until. Usually shown as a month and a year, you can use your credit card up until the last date of that month in that year.

•   Late fee: The late fee is a charge you’ll incur if you miss making at least your minimum payment by your payment due date. To avoid this fee, it’s important to alway pay on time, even if you’re in the midst of disputing a credit card charge, for instance.

•   Minimum payment: The credit card minimum payment is the least amount you must pay each month on your outstanding balance. This can be a flat amount or a percentage of your outstanding balance.

•   Purchase APR: The APR for purchases represents the total annual cost of borrowing money through purchases made with your credit card. This APR applies only on remaining balances after the statement due date.

Decide on the Type of Credit Card You Need

There are a number of different types of credit cards out there that can serve different needs. For instance, there are:

•   Travel rewards credit cards

•   Cashback credit cards

•   Credit-building credit cards

•   Balance transfer credit cards

While most of the above types of cards are unsecured credit cards, meaning no deposit is required, there are also secured credit cards. These do require a deposit, though they may also be more accessible to those with limited or low credit.

Different types of cards offer different benefits, and they may also vary when it comes to things like annual fees or average credit card limits.

There may also be differences in the requirements for getting approved. It’s not so much a question of how old you have to be to get a credit card — rather, different cards may have varying requirements for minimum income or credit score needed to qualify.

Before applying, it’s a good idea to do some comparison shopping to find a card that not only fits your needs but also that you’re eligible for.

Check Your Credit Score

Your credit score is a number that indicates the likelihood that you’ll repay a debt. It’s based on your credit history, and banks use it as a tool for evaluating credit card applications and deciding whether to approve them.

Here are some common factors that can affect your credit score:

•   Payment history, including on-time payments, missed payments, and having an account sent to collections

•   Credit utilization, or how much one owes relative to their total available revolving credit

•   Length of credit history

•   Types of credit accounts

•   Recent activity, such as applying for or opening new accounts

Generally, the higher an individual’s credit score, the more creditworthy they’re considered. If using the FICO scoring model, here’s a general breakdown of what various scores mean:

•   Less than 580: Poor

•   580-669: Fair

•   670-739: Good

•   740-799: Very good

•   800+: Exceptional

It’s a good idea for an individual to know their score and their chances of getting approved before applying for a credit card. The minimum credit score for a credit card will vary depending on the type of card it is.

For example, rewards credit cards, which come with big perks, tend to require a good credit score. But some types of credit cards, such as secured credit cards, may be more accessible to those with lower credit scores because they pose a lesser risk to lenders. This can make the latter category more appealing if, for instance, you’re getting your first credit card.

It’s worth noting that pulling one’s own credit information is considered a “soft inquiry” and does not reduce their credit score. When you apply for a new credit card, however, it will generate a “hard inquiry,” which can lower your credit score temporarily.

Where to Apply for a Credit Card

Credit cards are offered through banks, credit unions, retailers, airlines, colleges and universities, and a host of other institutions. This means that there are a variety of places where one can apply for a credit card — and often a number of ways to apply.

You can apply for a credit card in person, such as at a bank branch or retail location. Or, you may apply over the phone. Most credit card issuers also offer online applications, which add convenience to the process.

How to Apply for a Credit Card in 3 Steps

Ideally, by the time you sit down to actually apply for a credit card, you’ll have done the necessary homework to determine if you should get a credit card. This includes checking your credit score and potentially getting preapproved (though more on that later).

1. Gather the Necessary Information

The application process will be easier — and likely quicker — if you’re prepared. This means gathering any necessary documentation (more on what you’ll usually need in the next section) and having reverent information on hand, such as your income and Social Security number.

2. Fill Out and Submit an Application

Next, it’s time to fill out the application. There are a few ways you can do this: online, over the phone, or through the mail. It’s generally quickest to complete an application online.

You’ll need to fill in the requested fields and upload (or make copies of) any necessary documents. Once you submit your application, you should hear back within a few weeks at the most — sometimes, you’ll hear back almost the same day.

3. Be Ready for the Credit Impact and Repayment

As you wait for your credit card to arrive in the mail, you should take stock of the recent hit you took to your credit from the hard inquiry. It’s generally advised to avoid applying for multiple credit cards or loans within a short period of time to minimize the credit impact.

Also start to consider your strategy for how you’ll repay your credit card balance once you start swiping. Consider setting up automatic payments from your bank account each month to make sure you’re not late, or you might set a reminder on your phone or in your calendar.

What Do You Need to Apply for a Credit Card?

While application requirements will depend on the credit card issuer, what you need to apply for a credit card generally includes:

•   Annual income

•   Address and length of time at that address

•   Date of birth

•   Phone number

•   Social Security number

•   Employment status and sources of income

•   Financial accounts and/or assets

•   Financial liabilities

•   Country of citizenship and residence

Credit Card Preapproval and Prequalification

Getting prequalified or preapproved for a credit card means you’ve been prescreened for a credit card and meet at least some of the eligibility requirements. The two terms can be used interchangeably, though preapproval might carry slightly more weight in terms of your odds of eventual approval.

You’ll still need to go through the formal application to get approved for a credit card though, as neither preapproval or prequalification means you’ve been approved. The formal application process will involve a hard inquiry, whereas prequalification and preapproval generally only involve soft inquiries.

Still, preapproval or prequalification can be a good way to suss out potential credit card options and likelihood of getting approved before you move forward with an application and risk the impact to your credit.

What Happens If Your Application Is Turned Down?

Getting turned down for a credit card is indeed disappointing. When a credit card application is declined, you have the right to know why. You can request details about your application in the form of an adverse action letter, which includes the reason for the denial, details about your credit score, and notice of the right to dispute the accuracy of information provided by the credit reporting agency.

This can serve as helpful context for understanding why an application was declined. It can also help in determining what the appropriate next steps are for improving one’s chances of approval, if and when you apply for another credit card. For instance, you may consider applying for a credit card that has less stringent credit requirements, or you may take steps to improve your credit score and try again at a later date.

Secured and Prepaid Credit Cards

If you were turned down for a credit card, you might take some steps to improve your credit before trying again, or you might consider other options. Two alternatives you might look into are secured credit cards and prepaid credit cards.

With a secured credit card, you put down a deposit, which serves as collateral and usually acts as the card’s credit limit. Because there’s collateral there for the credit card issuer to fall back on if you fail to make your payments, secured credit cards are generally easier to get approved to than the more traditional, secured credit cards.

Prepaid debit cards don’t let you work on building your credit, as you’re not actually borrowing funds. Rather, you load the card with funds that you can then use in person or online. This can offer some of the convenience that a credit card offers over cash, without the application and approval process.

The Takeaway

Applying for a credit card can be a simple three-step process of gathering the required details, submitting an application, and handling the likely credit impact. You will probably have many options when selecting a card, so take your time to find the right fit.

Whether you're looking to build credit, apply for a new credit card, or save money with the cards you have, it's important to understand the options that are best for you. Learn more about credit cards by exploring this credit card guide.

FAQ

How do I choose a credit card?

Choosing a credit card is a personal decision that depends on your needs, preferences, financial habits, and eligibility. Before applying for a credit card that appears to fit your needs, it’s a good idea to check your credit score and any other requirements, such as minimum income, to improve your chances of getting approved.

How long does it take to get a credit card?

The length of time it takes to get a credit card can depend on a number of factors, including the eligibility requirements and how an application is submitted. Some online credit card applications offer fast or even instant approval, although it can take some additional time for the credit card to arrive in the mail.

Does your credit get pulled when applying for a credit card?

Generally, a credit card company will do a hard credit inquiry before extending final approval. However, there may be some scenarios where a credit card issuer may only do a soft inquiry, such as if an individual has been preapproved for a credit card or already has a banking relationship with the credit card issuer.

What are the requirements needed to get a credit card?

The requirements to get a credit card will typically vary from card to card. However, you’ll generally need to provide information on your annual income, your employment status, and your current debt obligations. Your creditworthiness also comes into play, though credit score requirements will differ depending on the card.

Can you get a credit card with no credit history?

It is possible to get a credit card with no credit history, though your options may be more limited. You may have an easier time getting approved for a secured credit card or a basic, no-frills credit card.
