An electronic business card includes a printed circuit board, having a desired length and width, as well as front and rear major surfaces, functions as the substrate of the business card. Electrical components, a switch, and a direct-current source, such as a battery or voltage cell, are mounted to the printed circuit board. The electrical components, the direct current source and conductive elements of the printed circuit board cooperate to provide a desired circuit functionality powered by the direct-current source. The switch permits power supplied by the direct-current source to be selectively disconnected from the electrical components. For one embodiment of the invention, the direct-current source is a laminar, surface mounted battery that is attached to the rear major surface. The electrical components may include light emitting diodes, as well as flasher, audio and video componentry.
