A
credit card is a payment system.It is a small plastic card issued to users. In the case of
credit cards, the issuer lends money to the customers,and the money to be paid later to the merchant. It is different from a charge card or a debit card, which requires the balance to be paid in full each month.
Credit cards are issued after an account has been approved.It is done by the credit provider,bank.
Benefits:
Credit card providers often offer incentives such as frequent gift certificates,flyer points, or cash back to attract customers.These all because of intense competition in the credit card industry,
There low interest credit cards or even 0% interest credit cards are available. The only drawback to users is that the fixed period (about 6 and 12 months) of low interest credit cards, after which a higher rate is charged. Most such services charge a monthly or annual fee.
Grace period
A credit card's grace period is the time the user has to pay the balance before interest is charged to the balance. Grace periods vary, but range from 20 to 30 days depending on the type of credit card and the issuing bank.
Usually, if a customer is late to pay the balance, finance charges will be calculated and the grace period does not apply. Finance charges depend on the grace period and balance.But most od the credit cards have no grace period and interest is applied on both the previous balance and new transactions. There are few credit cards that will only apply finance charge on the previous or old balance, excluding new transactions.
