Java™ Ring
The Java™-powered Ring is a special version of the Digital Decoder Ring that runs Java™ Card 2.0, enabling multiple applications to reside in a single iButton. Dynamic objects, large stacks, and garbage collection give the form exceptional functionality. Fast-write nonvolatile RAM lets applets be added or deleted on demand, giving you the ability to update. Services not even envisioned today can be added in the future by downloading applets. With RAM ranging from 6Kbytes to 134Kbytes, this Java™ computer can take on the more complex tasks envisioned for e-commerce, delivering end-to-end connectivity.
Java™-powered iButton DS1955B or DS1957B.
Note: You must know your ring size to order. You cannot re-size the ring.
Note to customer: The iButton needs to be ordered from Dallas Semiconductor prior to installation the iButton to the ring shank.
