Abstract
Key-like portable electronic identification devices and other electronic devices adapted to be inserted into mating electrical receptacles. The bodies of the devices in their preferred embodiments are formed of plastic molded around a printed circuit substrate, the barrels of which, when positioned on edges of the board, are modified so as to function as electrical contacts. Simplified and improved encoding is provided by a set of fusible links. Dispersal space is provided around the fusible links for fused material to prevent reformation of a fused link.
