A credit card is part of a system of payments named after the small plastic card issued to users of the system. It is a card entitling its holder to buy goods and services based on the holder's promise to pay for these goods and services. The issuer of the card grants a line of credit to the consumer (or the user) from which the user can borrow money for payment to a merchant or as a cash advance to the user. A credit card is different from a charge card, where a charge card requires the balance to be paid in full each month. In contrast, credit cards allow the consumers to 'revolve' their balance, at the cost of having interest charged. Most credit cards are issued by local banks or credit unions, and are the shape and size specified by the ISO/IEC 7810 standard as ID-1.
How Does a Credit Card Number Work?
Beginning Digit
The beginning digit lets the machine know what system the credit card is using. Each system is assigned a number. A few common system number are: 3 for American Express, 4 for Visa, 5 for MasterCard and 6 for Discover Card.
Second Set of Digits
The digits following the beginning digit identify what bank the card belongs to. This can include the first 6 digits. There are many different banks that give out credit cards. Each one has its own set of codes and these will be displayed on your card right after the system number.
Third Set of Digits
The digits following the bank's identity would be your account number at that bank. These digits come after the bank identification number and don't stop until just before the very last number. This number ensures that your account is charged for your purchases.
Final Digit
The last digit on the credit card is your validity check code.
Expiration Date
The expiration date is a set of numbers on the bottom right corner of the card. It tells you and any merchants how long the card is good for. Once the date passes, the card is no longer valid and you can't use it. Usually the credit card company will issue you a new card before the old one expires. If it doesn't, call and request a new one.
Three-Digit Security Code
For your added protection there is a 3-digit security code on the back of the credit card. It is just past the white strip where you sign your name. You may be asked for this number when you make transactions online. This will let the merchant know that your card is legitimate.
Credit cards are not complicated to use or to understand. But if you don't take the time to understand how your credit card works, you might wind up having a large balance, paying a huge fee each month and running up a high amount of interest. Consumers can apply for thousands of credit cards from all different companies--banks, department stores, credit unions, gas companies and so on. Some credit cards have better interest rates than others, and you can definitely find one without a yearly fee. The better your credit rating, the better credit card deal you will be offered. Make sure you know how your particular credit card works before you use it.
Read through different credit card brochures to choose the one that is right for you. Will you use your card often and want to accumulate points for merchandise, trips or some place special like Disney World? Do you want an American Express card or Visa? Look at the interest rates--your bank may offer you a better interest rate than a department store. Once you've read through several brochures carefully, choose the credit card that best fits you and your family's needs.
Fill out the credit card application and send it in. You can also apply for some credit cards over the phone or Internet, or in person at a bank or department store. Most credit card companies, especially ones that are offering you low interest and no annual fees, will put your name through a credit check to make sure you pay your bills on time and that you would be a reliable <http://www.ehow.com/how_4558150_how-credit-card-works.html> customer.
Use your credit card when you make purchases. Make sure you save your credit card receipts from purchases in one central location. You will want to check your receipts against your credit card statement at the end of the month.
Decide if you will pay the whole amount you charged during the month or a portion when you get your credit card statement. The credit card company will give you a minimum payment. This is the amount that you have to pay in order to keep a good credit rating <http://www.ehow.com/how_4558150_how-credit-card-works.html>. Check the charges on your statement with the credit card receipts you collected during the month to make sure that you are not charged for something you did not purchase.
Remember, if you only pay the minimum payment, the credit card company will charge you interest on your leftover balance. This is how credit card companies make money. If you do not want to pay any extra, then pay your entire balance each month.
Send your payment at least five days before the due date <http://www.ehow.com/date/>. Pay attention to holidays and weekends. You can sometimes pay your balance over the phone or over the Internet. Sometimes, the credit card company charges you an extra fee to pay over the phone. You will have to check with your individual credit card company.
Also, most financial institutions charge a late fee if the payment is received after the due date; and if you had a special introductory deal, this will often be in trouble if you pay late. A credit card can work for you and your family, but you have to be responsible and make sure you understand how it works.
Identity theft is real and a problem for many people. To help guard against identity theft, don't sign the back of your credit card. Write "See ID" in the place where there is a signature. When a clerk checks you out and accepts your credit card, they should ask to see your driver's license or other picture ID.
APR is Not the Real Interest Rate
The usual misconception with credit-card Annual Percentage Rates (APRs) is this number is the actual interest annually charged for the account. It is not. In annual terms, a credit card's <http://www.ehow.com/how-does_4925318_apr-work-credit-card.html> APR merely is an estimate of what the interest rate is or will be in the near future. Even given stable conditions, the APR is just a partial reflection of the real interest rate, Effective Annual Rate (EAR). Unstable conditions can result in the APR having little resemblance to what the EAR will be by the end of a fiscal year.
APR in Practice
The APR on a credit card usually is an expression of the interest on the credit card if it were compounded daily, not annually. Given stable conditions, an APR of 12.99 percent compounded for a year is the same as an EAR of 13.88 percent. But some credit cards are compounded monthly instead of daily. Then math would convert a 12.99 percent APR into a 13.79 percent EAR. The difference might only be between 1 percent and 2 percent, but that can add up over time, especially when carrying a high account balance <http://www.ehow.com/how-does_4925318_apr-work-credit-card.html>.
Why APR and not EAR?
EAR is what is commonly imagined when it comes to interest rates <http://www.ehow.com/how-does_4925318_apr-work-credit-card.html> because something similar is applied to most loans with fixed payments, such as mortgages and car loans. It is not applied to credit cards because it is not a legally recognized term in many states, especially the two where most credit card companies keep their headquarters: Delaware and North Dakota. The legal definition of APR is structured to favor the somewhat misleading approach to interest rates used by credit card companies, so be careful and understand what you are using. Your best bet is to pay off your card balance each month or you are at their mercy.
Many marriages end because of credit card debt. If you are married, make sure the both of you understand and agree fully as to how you are going to use your credit cards. Your other alternative is to get a debit card and that way you cannot spend any more money than you have in the bank. That too has to be used carefully as you will need money left in the account to cover emergencies and payments on their due dates. Also, you are probably better off to have only one credit card. One card is easier to manage.
Your credit score can literally control your life so be careful how you spend or borrow. Two of the most important things you will purchase are cars and homes. You have to have a good credit score to qualify and a bad credit score will follow you for 7 years.
Remember if you spend rather than borrow, you will not have to pay interest because you are spending your money not theirs, and can't spend more than you have. Even when spending your money, make sure you don't spend something you will need for other bills coming due. Check with your mate before using the debit card to make sure you will not be in store for a shocking harmful surprise.
Finances are something that a couple needs to work on together. If you do that, you will have less pressure and be happier. It is not about one or the other being the boss, but the two of you understanding totally what is going on. This is why in the bible it says God wants the two of us to become one. One in heart and mind makes life a whole lot more pleasant. If your spouse is not available to reach at the time you are shopping, check with them in advance or wait until they are reachable. It is better to wait than to make a big mistake.
