ABSTRACT:
An autodialer with code feature, has a credit card sized carrier which contains; an audio transducer mounted to the carrier and activatable to produce tones that are comprehensible as discreet numerals and symbols by a touch-tone dialing system. A memory in the carrier stores a first sequence of numbers representing a telephone number and a second sequence of numbers representing a personal code. A control operatively connected to the memory and to the audio transducer, reads the first and second sequence of numbers and drives the audio transducer to generate tones corresponding to each number in each number sequence. A power supply mounted in the carrier is connected to the control, the memory and audio transducer for powering the control, memory and audio transducer. A first activator switch is connect to the control for controlling the control to read the first sequence of numbers only and generate tones in the audio transducer corresponding to the first sequence of numbers. A second activator switch spaced and separator from said first activator switch, is connected to the control for controlling the control to select the second sequence of numbers only and to activate the audio transducer according to the second sequence of numbers.
