A credit card is a payment card issued to users (cardholders) as a method of payment. It allows the cardholder to pay for goods and services based on the holder's promise to pay for them. The issuer of the card (usually a bank) creates a revolving account and grants a line of credit to the cardholder, from which the cardholder can borrow money for payment to a merchant or as a cash advance. The ease in swiping a credit card for a purchase has its pros and cons. It may either help when handled properly or become a detriment. If you are able to pay your bills on time every month and not carry over a balance, credit cards are a great convenience. The cards can also land you deep in debt. This often occurs if you're unaware of the terms of the credit card agreement and if you carry too many cards.
