Credit cards allow cardholders to access a line of credit at will for purchases and cash advances. The limit on the line of credit is established by the credit grantor and is based on a number of factors that determine the cardholder’s creditworthiness, or ability to pay back the loan.
The main credit card issuers are Visa, MasterCard and Amex.
Credit cards are the actual payment instrument used by a cardholder in a retail or online establishment to purchase goods or services that allow them the option to pay in full at a later date, usually a maximum of 59 days credit before any interest payments are due.
For providing credit, card issuing banks and institutions are paid a fee, in the form of interest which a cardholder will pay in addition to the principle balance owed for the original purchase.
The main difference between UK and US credit cards is their use. All three types of cards are available in both countries; however, the UK prefers to utilize charge cards, paying off balances at the end of the month, while Americans tend to revolve lines of credit, amassing debt.
