Credit Card 101

Before indulging much into the never-ending list of the advantages and disadvantages of having a credit card, it is very important for people to first have a brief realization of what credit card really is in order for them to maximize its potentials.

In layman's terms, credit card is a card that allows a person to make purchases up to the limit set by the card issuer. One must then pay off the balance in installments with interest payments. Usually, credit card payment per month ranges from the minimum amount set by the bank to entire outstanding balance. And since it is a form of business, the longer the credit card holder wait to pay off his or her entire amount, the more interest pile up.

Since having a credit card is a responsibility, only those people who are of legal age and have the capability to pay off the amount they are going to spend through their credit card, is allowed to have one. Actually, most of the adults in the U.S. use credit card because this is very convenient compared to carrying cash or checks every time they have to purchase something.

It is also equally important to be familiar with the different types of credit cards before you begin to build up credit card balances and to avoid having a nightmare of debt. Since credit cards are indispensable to most consumers, it is a must that they understand the types of card that include charge cards, bankcards, retail cards, gold cards and secured cards. All of these types come in one of two interest rate options-the fixed and variable. Actually, it doesn't really matter if you decide to have a fixed-rate credit card because the interest rate remains the same. Compared to variable rate cards where rate may be subject to change depends upon the credit card issuer's discretion, fixed-rate carry higher interest rates. Basically, credit card grantors issue three types of accounts with basic account agreements like the "revolving agreement" a.k.a. Typical Credit Card Account which allows the payer to pay in full monthly or prefer to have partial payments based on outstanding balance. While the Charge Agreement requires the payer to pay the full balance monthly so they won't have to pay the interest charges, the Installment Agreement, on the other hand, asks the payer to sign a contract to repay a fixed amount of credit in equal payments in definite period of time. Another category of credit card accounts includes the individual and joint accounts where the former asks the individual alone to repay the debt while the latter requires the partners responsible to pay. The common types of credit cards available through banks and other financial institutions also include Standard Credit Cards like Balance Transfer Credit Cards and Low Interest Credit Cards; Credit Cards with Rewards Programs like Airline Miles Credit Cards, Cash Back Credit Cards and Rewards Credit Cards; Credit Cards for Bad Credit like Secured Credit Cards and Prepaid Debit Cards; and Specialty Credit Cards like Business Credit Cards and Student Credit Cards.
