Java Ring: At the 1998 JavaOne conference Sun and Dallas Semiconductor distributed rings and ring readers. The pinky rings contained an embedded chip that encoded whether you liked cream or sugar in your coffee, and a unique id. The rings are big and silver, looking like something from an 1940’s Green Hornet episode. The reader/encoders interface via a standard serial or parallel port. The rings could be used for robust, low cost mag stripe card sorts of applications. You can buy a development kit with a ring and your choice of serial or parallel reader for $50.00 USD from iButton. You can download software from the iButton site.
