Abstract

A pay telephone includes a keypad, a card reader, and a processor. The keypad receives input signals from a caller. The card reader reads identification data and speed dial numbers from a card received from the caller. The processor receives the input signals from the keypad and the identification data and speed dial numbers from the card reader, and concurrently validates the card using the identification data and initiates a telephone call using the input signals or the speed dial numbers.
