Credit Matters

A Primer on Credit Card Use

A credit card is a great financial tool. It can be more convenient to use and carry than cash, and it offers valuable consumer protections under federal law. At the same time, it's a big responsibility. If you don't use it carefully, you may owe more than you can repay, damage your credit rating and create credit problems for yourself that can be difficult to fix.

Chances are your mail is full of offers from credit card issuers. How do you know if the time is right for a credit card? Here is some important information that may help you determine whether you're ready for plastic, what to look for when you select a company to do business with, and how to use your credit card responsibly.

Please note that this guide was designed primarily for a U.S. audience. While many of the general topic areas may be relevant in other parts of the world, specific details are U.S. based.

Qualifying for a Credit Card

If you're at least 18 years old and have a regular source of income, you're well on your way to qualifying for a card. But despite the invitations from card issuers, you'll still have to demonstrate that you're a good risk before they grant you credit. The proof is in your credit record. If you've financed a car loan or other purchase, you probably have a record at a credit agency (CRA) (The most common type of CRA is the credit bureau). This credit history shows how responsible you've been in paying your bills and helps the credit card issuer decide how much credit to extend.

Before you submit a credit application, get a copy of your report to make sure it's accurate. Contact the credit bureaus listed in the telephone directory under "credit" or "credit rating and reporting." Because more than one credit bureau may have a file on you, call each until you locate all the agencies maintaining your file. The three major credit bureaus are:

  • Equifax
    P.O. Box 740241
    Atlanta, GA 30374-0241
  • Experian (formerly TRW)
    P.O. Box 949
    Allen, TX 75013-0949
    1-888-EXPERIAN (397-3742)
  • Trans Union
    P.O. Box 390
    Springfield, PA 19064-03090

Anyone who takes action against you in response to a report supplied by a CRA – such as denying your application for credit – must give you the name, address and telephone number of the credit bureau that provided the report.

Establish a Good Credit History

Suppose you haven't financed a car loan, a computer, or some other major purchase. How do you begin to establish credit? First, consider applying for a credit card issued by a local store and use it responsibly. Ask they report to a credit bureau. If they do – and if you pay your bills on time – you’ll establish a good credit history.

Second, consider a secured credit card. It requires that you open and maintain a bank account or other asset account at a financial institution as security for your line of credit. Your credit line will be a percentage of your deposit, typically from 50 to 100 percent. Application and processing fees are not uncommon for secured credit cards. In addition, secured credit cards usually carry higher interest rates than traditional nonsecured cards.

Third, consider asking someone with an established credit history -- perhaps a relative -- to co-sign the account if you don't qualify for credit on your own. The co-signer promises to pay your debts if you don't. You'll want to repay any debt promptly so you can build a credit history and apply for credit in the future on your own.

A positive credit history is an asset, not only when you apply for a credit card, but also when you apply for a job or insurance, or when you want to finance a car or a home.

If Your Application Is Denied

If you're turned down for a card, ask why. It may be that you haven't been at your current address or job long enough. Or that your income doesn't meet the issuer's criteria. Different credit card companies have different standards. But if you are turned down by several companies, it may indicate that you are not ready for a credit card.

If you've been denied credit because of information supplied by a credit bureau, federal law requires the creditor to give you the name, address and telephone number of the bureau that supplied the information. If you contact that bureau within 60 days of receiving the denial, you are entitled to a free copy of your report. If your file contains accurate negative information, only time and good credit habits will restore your credit-worthiness. If you find an error in your report, you are entitled to have it investigated by the credit bureau and corrected at no charge.

You should dispute any inaccuracy in your report with the credit bureau and also with the company that furnished the information to the credit bureau.

Get the Best Deal

Fees, charges, and benefits vary among credit card issuers. When you're choosing a credit card, shop around. Compare these important features:

  • Annual percentage rate (APR). The APR is a measure of the cost of credit, expressed as a yearly interest rate. Check out the "periodic rate," too. That's the rate the issuer applies to your outstanding balance to figure the finance charge for each billing period. For example, if you have an outstanding balance of $2,000, with 18.5 percent interest and a low minimum monthly payment, it would take over 11 years to pay off the debt and cost you an additional $1,934 just for interest, which almost doubles the total cost of your original purchase.
  • Grace period. This is the time between the date of a purchase and the date interest starts being charged on that purchase. If your card has a standard grace period you have an opportunity to avoid finance charges by paying your current balance in full. Some issuers allow a grace period for new purchases even if you do not pay your balance in full every month. If there is no grace period, the issuer imposes a finance charge from the date you use your card or from the date each transaction is posted to your account.

  • Annual fees. Many credit card issuers charge an annual fee for granting you credit, typically $15 to $55. Some issuers charge no annual fee.
  • Transaction fees and other charges. Some issuers charge a fee if you use the card to get a cash advance, if you fail to make a payment on time, or if you exceed your credit limit. Some may charge a flat fee every month whether you use the card or not.
  • Customer service. Many issuers have 24-hour, toll-free telephone numbers.
  • Other benefits. Issuers may offer additional benefits, some with a cost, such as: insurance, credit card protection, discounts, rebates, and special merchandise offers.

Kinds of Credit Accounts


  • Revolving agreement. A consumer pays in full each month or chooses to make a partial payment based on the outstanding balance. Department stores, gas and oil companies, and banks typically issue credit cards based on a revolving credit plan.
  • Installment agreement. A consumer signs a contract to repay a fixed amount of credit in equal payments over a specific period of time. Automobiles, furniture and major appliances often are financed this way. Personal loans usually are paid back in installments, too.

Protect Your Credit

Once you get a card, sign it immediately so no one else can use it. Note that the accompanying papers have important information, such as customer service telephone numbers, in case your card is lost or stolen. File this information in a safe place.

Call the card issuer to activate the card. Many issuers require this step to minimize fraud and to give you additional information.

Keep your account information to yourself. Never give out your credit card number or expiration date over the phone unless you know who you're dealing with. A criminal can use this information to steal money from you, or even assume your credit identity.

Keep copies of sales slips and compare charges when your bill arrives. Promptly report in writing any questionable charges to the card issuer.

Don't lend your card to anyone, even to a friend. Your credit privilege and history are too precious to risk.

You're Responsible

While a credit card makes it easy to buy something now and pay for it later, you can lose track of how much you've spent by the time the bill arrives if you're not careful. And if you don't pay your bill in full, you'll probably have to pay finance charges on the unpaid balance. What's more, if you continue to charge while carrying an outstanding balance, your debt can snowball. Before you know it, your minimum payment is only covering the interest. If you start having trouble repaying the debt, you could tarnish your credit report. And that can have a sizable impact on your life. A negative report can make it more difficult to finance a car or home, get insurance, and even get a job.

Federal Protections

Federal law offers the following protections when you use credit cards.

  • Errors on your bill. You must notify the card issuer in writing within 60 days after the first bill containing the error was mailed to you. In your letter, include: your name; account number; the type, date and amount of the error; and the reason why you believe the bill contains an error. In return, the card issuer must investigate the problem and either correct the error or explain to you why the bill is correct. This must occur within two billing cycles and not later than 90 days after the issuer receives your letter. You do not have to pay the amount in question during the investigation.
  • Loss or theft. If you lose your credit or charge cards, or if you realize they’ve been lost or stolen, immediately call the issuer(s). By law, once you report the loss or theft, you have no further responsibility for unauthorized charges. In any event, your maximum liability under federal law is $50 per card.
