First, compare the interest chargeable for all the credit cards for which you are eligible. While the rate may not remain fixed indefinitely, it’s always advisable for first timers to go for the one charging lower rates.

Read the fine print, especially on the other charges that may be charged on you, like late-payment fees, annual fees, and whether there is a grace period which is normally given before the finance charges kick in.

Decide what limit is appropriate for a person of your income. Also the fewer credit cards you have, the better placed you are to track your spending.

Compare the services and other features such as the cash back incentives, or warranties, rebates and the like.

Check whether the card is widely accepted to enable you to pay for your needs.

Annual Percentage Rate. This is the measure of the yearly cost of credit.

Finance Charges. These are the total charges involving the transaction.  This is the period the issuer gives you before he starts charging you interest on new purchases. Note that not all credit cards have a grace period.

It comes as a surprise how credit cards have found their way into our lives (and out wallet). Credit cards have gradually turned into becoming a necessity (rather than luxury). You can find credit card processing machines in almost all the shops today. With the advent of internet, online credit card processing has become popular too. Credit card processing as such is a really interesting topic. This article tries to put into perspective the people, systems and the equipment that go into credit card processing.

First, letís check the equipments used for credit card processing. So, there are credit card processing software for online credit card processing, there are credit card processing machines (i.e. the credit card reading machines at shops), there are data verification/validation devices/software that verify the security information on credit cards, there are communication devices/systems that enable safe transfer of credit card information from one point to another, and then there are other credit card processing equipments like the credit card processing equipment that is used for the preparation of the actual plastic (credit card).

Then there are various service providers that provide services related to credit card processing.

Then there are postal and courier service that help deliver credit card bills in time.

Besides that there are complete systems for processing credit card applications, there are systems for credit card bill processing/generation, there are people at call centers who help in addressing the queries from credit card holders and, very importantly, there are people (sales representatives) who help you in filling the credit card application forms. Another important entity with regards to credit card processing process is the credit rating bureaus. Credit card bureaus maintain a database of credit ratings for individuals and businesses. This rating is based on the data received from various credit providers over a period of time. This rating is the most important part of credit card application processing and a bad rating can lead to rejection of the credit card application altogether.

Thus, credit card processing involves a coordinated effort from a lot of professionals and service providers. In that sense, we can also say that credit card processing is an industry in itself that has generated a lot of employment.

Whatís the thing that is most prominent on any credit card ad? Well, itís the credit card rate (or the APR, as we know it). The credit card rate is the most publicized thing in the world of credit cards. A lot of people just compare the credit card rate of various credit cards and just go for the one that is offering the lowest credit card rate (or APR). Credit card rates are, in fact, one of the most important factors in the selection of a credit card (though not the only factor). Therefore, a proper understanding of Credit card rates is even more necessary.

So, what is a credit card rate or APR? Very simply, credit card rate is the rate of interest that the credit card supplier will charge you with on the amount you owe them. The credit card supplier will charge you an interest only if you donít make full payments in time.  When you receive your credit card bill, it specifies the full amount you owe the credit card supplier. It also specifies the minimum payment that you must make (by a particular date), in order to avoid incurring a late fee and other inconvenience. You have the option of making either a full payment or just the minimum payment. If you make a full payment (by the due date), you are not charged any interest.

However, if you decide to go with the minimum payment or some amount that is lesser than the full amount, the credit card supplier will charge interest based on the credit card rate and the balance amount. This credit card rate is the interest rate that you agreed with them at the time of applying for the credit card. The credit card rate or the annual percentage rate, as is obvious, is an annual interest rate. The credit card suppliers use this annual credit card rate to calculate the monthly credit card rate and then they calculate the interest on the balance amount that you owe them. The balance amount here is simply = Full amount ñ (payment made by you). This interest is added to your balance for the next month (at the time of next billing cycle). If you again make a partial payment, the new balance is calculated again and the credit card rate (monthly one) applied to it for calculation of new interest; and it keeps going on and on until you make the full payment.

Thatís how credit card rate acts in this vicious circle. Hence, credit card rate is termed as the most important consideration in choosing a credit card.
