Prepaid long distance calling card automatic reader dialer

摘要

A process and device for connecting prepaid long distance 800 numbers and pin numbers to service providers' networks. The device has a magnetic reader, a microprocessor controller, and a DTMF generator. The magnetic reader reads the 800 number and the pin number from the encoded magnetic strip attached to the prepaid long distance calling card. The microprocessor is electrically coupled to the magnetic reader and programmed to receive and store the 800 number and the pin number. The microprocessor is electrically coupled to the DTMF generator and is programmed to transmit the 800 number to the DTMF generator. The DTMF generator dials the 800 number and connects to the prepaid long distance carrier's network. Once the carrier's network has been accessed, there is a voice prompt. The microprocessor is electrically coupled to three buttons and is programmed to transmit the designated tones: one for English, two for Spanish, or the pin number.
