Abstract: A disposable cellular telephone and business card combination. The cellular telephone circuit is printed on a paper substrate with a conductive ink. A paper microphone diaphragm is attached to one end of the business card and a paper speaker diaphragm is attached to an opposite end of the business card. The microphone and speaker diaphragms are electrically coupled to the circuit, and are attached to the paper substrate in any suitable manner that allows them to vibrate relative thereto. A thin flexible battery cell is formed in the paper substrate at any suitable location so that it doesn't interfere with the position of the circuit, microphone or speaker. A filament antenna is formed in the business card so that it can be extracted therefrom when using the card as a cellular telephone. A switch is provided on the business card that when activated causes a predetermined number to be dialed associated with the text on the business card.
