A credit card is much more than a plastic rectangle; it's a form of payment that can be used as a short-term loan. Used wisely, a credit card can help your finances by improving your credit score. Misused, a credit card can spell doom for your finances and your credit score.

An Absolute Beginner's Guide to Credit Card Basics

A credit card is a form of payment that can be used as a short-term loan — or simply for convenience. When you make a purchase and pay with a credit card, you're simply deferring payment until you receive a bill for that purchase online or through the mail.

If you pay your credit card bill in its entirety by its due date, you can avoid interest charges and pay only the original cost of your purchase. If you choose, however, you can pay a minimum payment on your credit card and carry a balance from month-to-month. During this time, credit card interest will accrue on the balance you carry.

The following outline illustrates the different steps you'll go through as you apply for a credit card, get approved and begin using it as a form of payment.


When you decide it's time to apply for a credit card, you'll fill out a credit application. Credit card applications ask for an array of personal and financial details, including your Social Security number, household income and home address. Our guide on the different types of credit cards available can help you decide which type of credit card is best for your situation, whether it's a balance transfer card, low-interest card, cash back credit card or another credit product.


Since a credit card extends a line of credit that works like a loan, banks use your financial details to assess your creditworthiness. Most banks look for applicants who have a stable income, low debt obligations and an acceptable credit history. Our guide on getting your first credit card can help you determine whether your credit and income are sufficient to apply for your first card.


Once your line of credit has been approved, you'll receive your card in the mail along with a credit limit. This limit represents the sum total of the money you can spend on your card. Use your card to make as many purchases as you want, but only up to your prescribed credit limit. Once you reach your limit, you'll need to pay down your balance if you want to put additional purchases on your card.


Once per month, your credit card issuer will send you a credit card statement that includes a summary of your purchases. Along with your statement, you'll receive an outline of your monthly minimum payment obligation. At this point, you should check your statement for accuracy and take note of your credit card bill's due date. In addition, you should take note of your credit card's annual percentage rate, or APR. If you choose not to pay your balance in full, this percentage represents how much interest accrues on your purchases each day.


Once you receive your statement and conceptualize your monthly payment, you can decide how to pay your balance down. The minimum payment included in your bill represents the lowest amount of money you can pay without incurring a penalty. However, you can pay any amount larger than the minimum if you want to minimize the interest you're charged and pay off your credit card balance faster. If you need help with your credit score, it may help to research the type of scores and ways to improve credit scores. Either way, your credit activities will be reported to the three largest national credit reporting agencies — Experian, Equifax and TransUnion.

For students or people with no credit history or a poor credit score, getting approved for a credit card can be challenging. If you find yourself struggling to get a credit card, no need to worry as these cards for no credit or poor credit are designed to help you build your credit.

How to Read Your Credit Card Statement

The following graphic was created to mimic a typical credit card statement. Keep in mind, however, that not all credit card statements look exactly alike. While all of the information included on the statement example below will be included on any statement you receive, it might be listed in a different spot or introduced with slightly different terms.

This is a mock credit card statement that people will typically receive.
Account number

This unique number helps your card issuer recognize your account.

Previous balance

This figure represents the balance on your card during last month’s billing period.


This figure represents credits made to your account during last month’s statement period.

Other credits

Other credits to your account generally include returns made on your card.


The total of purchases you made during this month’s billing statement period.

Balance transfers

A balance transfer occurs when you transfer a credit card balance from an old card to a new one — any balances transferred during this billing period will be listed here.

Cash advances

Cash advances are cash loans you take against your credit card and your credit account. Generally speaking, cash advances are charged higher interest rates and come with additional fees.

Past due amount

Any amount past due will be notated here.

Fees charged

Any fees the card issuer charged you.

Interest charged

This number is the amount of interest you’re paying to carry a balance this month and is determined by your annual percentage rate (APR).

New balance

This is the balance on your credit card as of your statement closing date — you can choose to pay this balance in full, make the minimum payment, or pay any amount in between.

Credit limit

Your credit limit represents the total sum of money you can spend on new purchases with your account.

Available credit

Your available credit is the amount of your credit limit left to spend after subtracting your current balance.

Statement closing date

All activity on your credit card starts on the date after your last statement date and ends on this date.

Days in billing cycle

We tend to think of months. But banks think in 30-day cycles.

Call customer service

Some credit card issuers have dedicated teams to answer calls from customers using a certain card. Your customer service team’s number may be unpublished.

Lost or stolen card

Call your card issuer as soon as you discover your card is missing or stolen.

Minimum payment due

This is the minimum amount of money you need to pay towards your credit balance this month.

Payment due date

Your card issuer must receive your payment by this date if you want to avoid penalties and late fees.

Late payment warning

Note the fee and increased interest rate you may pay if you make a late payment.

Minimum payment warning

The federal government recently started to require credit card issuers to make clear disclosures of the penalties consumers pay for making late payments.

uninsured icon

By law, you have a minimum of 21 days to make your minimum payment. Your bank or credit union may give you more time, such as 28 days, which is what our hypothetical bank does in the above example. Regarding payment date, subtract a day or two from your bank's deadline. Some banks will consider payments made on the date due as late.

Payment Timeline: When to Pay Your Bill

When you use your credit card to make a purchase or multiple purchases, it's crucial to keep a close eye on timing when it comes to your payment. Your credit card statement does the bulk of the heavy lifting for you by listing your minimum required payment and due date, but that doesn't mean the situation is entirely cut and dry. Here's an example of how your payment timeline might look once you start using credit:

Start of cycle

Day 0: May 20, 2021
You have a $1,255.26 existing credit card balance.


Day 1: May 21, 2021
You spend $529.27 on purchases with your credit card.

No new purchases

Days 2 through 29
Your account balance remains constant with no interest accrued on your new purchases. Your balance from last month, however, continues to accrue interest.

Billing statement closes

Day 30: June 19, 2021
Your billing statement closes. You now owe a balance of approximately $1,800.

Day 58
You review the bill and submit payment within your bank's 28-day deadline.

Day 65
Mail your payment in approximately one week from receiving it to leave plenty of time for your bank to receive it and process it.

Card Statement Review Checklist

Verify that all charges on your statement are yours, and correct. Once you receive your statement in the mail, you'll want to look each charge over carefully to verify that it was yours and that the number is correct.

Check to see if your bank or credit union credited your payments

Once you have made at least one payment on your credit card, you'll want to check subsequent credit card statements to make sure your payment was credited to your account in full.

Watch for surprise bank fees

Surprise bank fees can include late fees, over-the-limit fees and cash advance fees. If you are charged any of these fees as a mistake, you'll want to report it to your card issuer immediately.

Glance at your interest rate

Your annual percentage rate, or APR, is the percentage of interest you're charged if you carry a balance. Glance at your statement to make sure this rate is correct and hasn't changed for any reason.

Double check your due date — and plan for it

If you pay your credit card bill late, you may need to pay a late fee and might experience a negative impact to your credit score. To avoid a late payment, take note of your due date and plan to pay early.

creditCard2 icon

A "credit card" and a "charge card" are not one and the same. A charge card requires you to pay off your balance in full every month, whereas a credit card allows you to carry a balance for as long you make the minimum (or more) monthly payments.

What Happens the Instant You Swipe or Dip Your Credit Card

Using your credit card to make a purchase might seem convenient and seamless, but the reality is a fury of activity goes on behind the scenes. The following steps illustrate exactly what happens each time you whip out your card and say, "Charge it."

You get ready to pay and present your card.

A customer presents their credit card to a merchant in order to purchase products or services.

Your card is used to "pay" for merchandise or a service.

A customer either swipes their card on the point-of-sale card reader, or "dips" their card into the terminal if both parties use EMV chip technology.

Once the credit card is swiped or dipped, the card reader will contact the merchant's payment processor.

The processor will do one of two things — either contact the cardholder's bank and ask for approval directly or contact the bank's processor and ask for an authorization. While this may sound complex, all of these steps can take up just a few seconds combined.

Your transaction is approved or denied.

Once your card issuer receives the transaction and begins analyzing it, they will issue an immediate approval or deny your transaction. Most denials are due to a maxed out credit limit or suspicion of fraud.


If your purchase is approved by your card issuer, you'll receive a receipt for your purchase and complete the transaction.

If you spend more than $50, you'll generally need to sign for your purchase as well. At this point, a cashier or customer service agent may ask to see your identification to verify your identity.

A fee is deducted from the transaction, and paid by the merchant.

Most of the time, these fees vary from 1-6%. Once a purchase is made, this fee is deducted from the total transaction and paid by the merchant. On a $200 purchase, a merchant may be asked to pay a fee between $2 and $12.

The card issuer splits the fee with the payment processor.

The payment processor splits the fee with your card issuer so that both parties receive a cut of your transaction and turn a profit.

The consumer gets a cut in the form of rewards.

If you're using a rewards card that accrues cash back or rewards points, your bank will apply part of their fee towards your rewards balance.

Credit Card Security: A Growing Problem

According to the Federal Trade Commission, the government agency received more than 4.7 million reports in 2020 through its Consumer Sentinel Network. Nearly 1.4 million of those were related to identity theft — a number that has close to doubled since 2019.

The most common form of reported identity theft was government documents and benefits fraud (406,375 reports), followed by credit card fraud (393,207 reports). Other types of identity theft and fraud perpetrated against the American people include employment-related fraud and loan fraud.

Although private and small-scale fraud takes place on a large scale every day, some of the most notorious identity theft grabs and operations have taken place during large-scale data breaches during the last few years.

If you have been watching the news at all, you have probably seen how popular brands like Volkswagen and Wegmans have experienced data spills that have resulted in consumer data being put at risk. In addition, a report released in 2021 by the Thales Group found that nearly half of US companies surveyed reported experiencing a breach in the last 12 months, slightly higher than the global average.

Surely not all of those breaches dealt with consumer data or leaked credit card numbers. Still, it serves to underscore that the probability that your personal information will be compromised is high. And while much of the fall-out from data breaches is out of your control, one of the easiest ways to catch identity theft or fraud is to monitor your credit card activity and other accounts for any fraudulent use.

The Federal Deposit Insurance Corporation (FDIC) offers an array of tips that can help you protect yourself from fraud, regardless of the security of the merchants you use. These include:

  • Keep your personal information private: Don't share your personal financial details with anyone who requests them online or over the phone.
  • Verify requests for your personal details: Don't trust anyone who asks for your private financial details without confirming why they need them, and the legitimacy of their request.
  • Shred old receipts and statements: Don't leave printed financial information out where others can find it and read it.
  • Choose PINs and passwords that aren't obvious: Use a complex combination of letters, numbers and special characters in each password you use.
  • Inform your bank when you don't receive a statement: Likewise, contact your bank if you notice any fraudulent transactions on your account.
  • Check your credit report at least once per year: allows you to check your credit report with all three credit reporting agencies for free every year.

High-Security Credit Cards: How EMV Chip Cards Work

EMV technology, which stands for Europay, MasterCard and Visa, is the new global standard for credit card technology and fraud prevention. As of October 1, 2015, most merchants and card issuers in the United States were required to transition towards this technology — or face the prospect of more liability in the event fraud takes place.

Unlike traditional credit cards you swipe on the terminal, EMV-equipped cards add an extra layer of complexity — and protection — to each transaction. Once you "dip" your card into the terminal, your card's new microchip helps create a dynamic authentication process, which is much harder to crack and cannot be "skimmed" as the old swipe cards often were.

Since transactions made with EMV-equipped cards are encrypted from end to end, fraud perpetrated by crooked cashiers and scammers who place "skimming devices" should slowly cease to exist as this new technology takes hold. Purchases made online, on the other hand, won't receive this extra layer of protection since EMV technology is only useful for point-of-sale transactions.

Although EMV technology is a fairly new idea in the United States, it was first used in France as far back as 1992. The rest of Europe soon followed, and now it's a technology used worldwide. The hope is that, over time, the added security these cards offer will lead to fewer instances of fraud and lower costs for consumers, merchants and banks.

Hidden Lives of Credit Cards

This is a mock credit card front and back.
Location of the EMV chip

U.S. credit and debit cards are now getting higher-security EMV chips. Merchants must replace their old point-of-sale devices to read cards with EMV chips.

Expiration date

Typically three years after the issuing date. Cards expire on the last day of the month indicated on the card. Required by online merchants.

Name of authorized user

Person allowed to use the card. Account payment history is included in the authorized users' credit history. Required by online merchants.

Magnetic strip

Contains a digitized version of the account number, expiration date and name.

Authorized user’s signature

Merchants are allowed to compare the signature on the back of the card to the receipt you sign to verify you are the authorized user. A merchant may refuse to accept your card if you have not signed it.

Security code

Visa, MasterCard, Discover and American Express call the security code slightly different things, but the purpose is the same — it's designed to reduce fraud in card-not-present transactions. American Express places its code on the front of its cards. Required by online merchants.

How Banks Make Money Issuing Credit Cards

Although credit cards can serve as a valuable tool for your finances, they don't offer their services out of the kindness of their hearts. The truth is, they make small amounts of money as you use your card, then collect fees and credit card interest on the bank end. Here are some of the common ways banks profit from your use of credit:

  • Fees
    Fees can include transaction fees charged to the merchant (generally 1-6% of each purchase), annual fees, over-limit fees and late fees. While some fees (e.g. late fees, over-limit fees) can be avoided if you follow your card issuer's rules, other fees, like annual fees, may be required if you want to keep your card.
  • Interest
    When you carry a balance on your credit card each month, your balance gets charged credit card interest. The amount of interest you're charged is largely dependent on your cards annual percentage rate, or APR, which can run anywhere from 0-29%.
  • Selling your name
    Some card issuers make money by selling your name, address, and financial details to companies who may try to sell you a product or service. You will generally receive communication from these outside companies through traditional mail service, and sometimes, over the telephone.
