Abstract

A card-like device having a microprocessor and a speaker to communicate with telephone line, the device also including a single switch which when depressed by a user first activates the device and then causes a DTMF signal to be generated.

Claims

1. A telephone dialer card device comprising a microprocessor including a memory device for storing a signal corresponding to desired telephone number, a power source, said microprocessor having the capability of generating an electrical signal corresponding to said desired telephone number when activated, transducer means for converting the electrical signal to an acoustic signal for coupling to a telephone line, and switch means mounted on said card for supplying power from said power source to said microprocessor, said switch means being a first operative position when a user applies a firs amount of pressure thereto, said switch means being in a second operative position when a user applies a second amount of pressure thereto.

2. The device of claim 1 wherein said first amount of user pressure on the switch means activates said device and said second amount of switch pressure causes said acoustic signal to be generated.

3. The device of claim 2 further including resistor means coupled between said power source and said microprocessor whereby said microprocessor is in an initial lower power made prior to user pressure being applied to said switch means.

4. The device of claim 3 wherein said microprocessor returns to said initial lower power mode when user pressure is removed from said switch means.
