First Credit Card
A credit card is a system of payment named after the small plastic card issued to users. Issuer (financial firm) lends money to the consumer (or the user), a credit card allows the consumer to 'revolve' their balance, at the cost of having interest charged, but because of competition between the issuers, the customer (or the user) will have 0 interest charged if the balance is cleared within 30 days from the day of the transaction (a.k.a. Grace Period) and other benefits when using the credit card, such as free travel insurance, reward points, free gift and etc. Most credit cards are the same shape and size, as specified by the ISO 7810 standard.
