The Java Ring is an extremely secure Java-powered electronic token.Java Ring could have a number of real-world application.

The jewel of the Java Ring is the Java iButton -- a one-million transistor, single chip trusted microcomputer with a powerful Java Virtual Machine (JVM) housed in a rugged and secure stainless-steel case.
