Abstract: A Smart Card has an electronic circuit connected to a source of potential capable of destroying at least a portion of the electronic circuit. The potential is normally short circuited, but the path of the short circuit traverses a frangible portion of the card. When the portion is broken, so potential from the source is applied to destroy the portion of the electronic circuit.
