3. Introduction
A Java Ring is a finger ring that contains a small microprocessor with built-in capabilities for the user.
The Java Ring is an extremely secure Java-powered electronic token .
Its a sort of smart card that is wearable on a finger.
Its in fact a java smart card based on Java Virtual Machine that was proposed as the Java card 2.0.

The Java Ring is a stainless-steel ring, 16-millimeters (0.6 inches) in diameter, that houses a 1-million-transistor processor, called an iButton.
The ring has 134 KB of RAM, 32 KB of ROM, a real-time clock and a Java virtual machine, which is a piece of software that recognizes the Java language and translates it for the user's computer system

5. History
The java ring, which is powered by Java card was introduced at Sun Microsystems's JavaOne Conference, in March 1998.
It was developed by Dallas Semiconductor.
Workstations at the conference had "ring readers" installed on them that downloaded information about the user from the conference registration system.
This information was then used to enable a number of personalized services.

Java ring has been tested at School near Florida. The rings are given to students and have been programmed to;
store electronic cash to pay for lunches
automatically unlock doors
take attendance
store medical information
allow students to check out books.
Students simply press the signet of their Java Ring, and it performs the desired function.

7. Working
The rings given to students are programmed with Java applets that communicate with host applications on networked systems.
The Java Ring is snapped into a reader, called a Blue Dot receptor, to allow communication between a host system and the Java Ring.

9. More…
Whenever the user pushes his ring on a ring reader(Blue Dot Receptor), the corresponding application will take place.
The jewel of the java ring is the iButton.
iButton is a computer chip enclosed in a thick stainless steel can.
It uses 1-wire protocol for communication with the host and the iButton.

11. More…
Information is transferred between your iButton and a PC with a speed at up to 142kbps.
You simply touch your iButton to a Blue Dot receptor or other iButton probe, which is connected to a PC.
The Blue Dot receptor is cabled to a 1-Wire adapter that is attached to a spare PC port. 1-Wire adapters exist for USB, serial, and parallel ports. The Blue Dot receptor and 1-Wire Adapter are inexpensive

13. Security
National Institute of Standards and Technology (NIST) and the Canadian Security Establishment (CSE) have validated the DS1954 Cryptographic iButton as meeting Federal Information Processing Standards Publications (FIPS PUBS)
Java rings are authorized through Personal Identification Numbers (PINs) so that no one can steal a person's ring and use that ring.

14. Applications Electronic Access Control Time and attendance eCash
Gaming Systems
Opening the door
Asset management
Configuring car component

15. Conclusion
Java ring is highly durable because of its rugged and secure stainless packing.
Java ring is a small wearable ring with high secured data for easy transition of various kind of data.
