Claim:
A system for detecting tampering or unauthorized entry into a package formed from a blank having at least a pair of closure tabs, an inner surface and an outer surface, said system comprising: electrically conducting adhesive applied to each of said closure tabs; a programmable chip applied to one of said blank surfaces, said chip including a power source, procedure memory, data memory, clock means, and communication means; and electrically conducting trace means applied to one of said blank surfaces, one such trace means connecting said chip to the electrically conducting adhesive of one of said pair of closure tabs, and another of such trace means connecting said chip to the electrically conductive adhesive of the other of said pair of closure tabs; whereby with said blank having been formed into a closed package through adhesive joining together of said closure tabs, any separation of said tabs will break an electrical circuit which includes said trace means, said electrically conducting adhesive, and said chip means, which break will be recorded with a time stamp in said data memory of said chip.
