Card holders can pay for goods and services provided that the holder will pay for them later.

Visa

The first card launched was VISA in 1975, but the history tracks back to 1958 when Bank of America launched the first successful recognizably modern credit card in in Fresno, California. The card name was BankAmericard. BankAmericard changed its name to Visa in 1975. Before Credit Card, charge cards were introduced. A credit card is different from a charge card in a way that a charge card requires the balance to be paid in full each month. Charge card was first used in the 1920s, in the United States. Western Union had begun issuing charge cards to its frequent customers in 1921.

In 1966, the ancestor of MasterCard was born when a group of banks established Master Charge to compete with BankAmericard. Master card received a significant boost when Citibank merged its proprietary Everything Card (launched in 1967) into Master Charge (now known as Master Card) in 1969. The original banks behind MasterCard were United California and the Bank of California. In 1979, Master Charge The Interbank Card was renamed simply MasterCard.
