The rotary dial is a device mounted on or in a telephone or switchboard that is designed to send electrical pulses, known as pulse dialing, corresponding to the number dialed. It was first introduced in 1904 but did not enter service in the Bell System until 1919. The rotary dial was gradually supplanted by Dual-tone multi-frequency pushbutton dialing, introduced at the 1962 World's Fair, which uses a keypad instead of a dial.
The concept of using a card for purchases was described in 1887 by Edward Bellamy in his utopian novel "Looking Backward". Bellamy used the term credit card eleven times in this novel, although this referred to a card for spending a citizen's dividend rather than borrowing.  In 1950, Diners Club issued its first card - made of cardboard - for use in 27 restaurants in New York City.   American Express, which had specialized in traveler's checks, created its card in 1958 and also Bank of America mailed its first 60,000 BankAmericards (now Visa) to residents of Fresno, CA.
