Advantages of Using Java Ring

The Java Ring are very easy and convenient way for users. They are more secure than using passwords since passwords are short or can be guessed. Java Ring provides authentication to users which is crucial for many applications. It is easier for administrator to maintain the security infrastructure. And, it provides real memory, more power, and a capacity for dynamic programming. Java Ring used widely all around the world for several applications such as Access Control, Asset Management, e-Cash and for many other purpose.

Asset Management:
The Java Ring provides a simple, secure way of identifying a person or asset. It can serve as an electronic serial number that is never duplicated. With an memory up to 32k bytes, Java Ring can also give the asset their own personalized database. Each asset will have the ability to store unique information about itself and have that information permanently affixed to the asset. This makes Java Ring perfect for various asset management and data collection functions such as equipment maintenance records and inventory management. For example, The Sun concept car's security is based on a Java Ring that contains a profile of the user. By connecting your Java Ring to a ring receptor in the car, and the car knows, based on your profile, what you are allowed to do. In a family where both the husband and wife drive the car, each has individualized settings, so that when they enter the car, their environments are configured to the profiles on their rings. Java Ring are authorized through Personal Identification Number so that no one can steal a person's ring and run off with the car.



Access Control:
An Java Ring becomes a personalized key to protected assets and information. By touching the correct key to an iButton reader, the desired event, such as, opening a lock is enabled. Java Ring are perfect for various access control functions like access to buildings, computers, vehicles and equipment.



e-Cash:
Java Ring can be an personalized token and acts like a small change purse for one or multiple applications. It enables to complete transactions, like dispensing a candy bar or metering a prepaid volume of water. By using Java Ring, it eliminate the need to carry small amounts of cash, and it can service multiple, independent applications. They are perfect for a wide variety of e-Cash functions like mass transit systems, parking meters, gaming systems, vending and fleet refueling.


In additional, Java Ring can last longer than smart card. The silicon chip within the iButton is protected by the ultimate durable material: stainless steel. The iButton is wear-tested for 10-year durability. Moreover, the monolithic chip includes up to 134 K of SRAM that is specially designed so that it will rapidly erase its contents as a response to an intrusion. Rapid erasing of the SRAM memory is known as zeroization. When an iButton detects any intrusion, it erases its private keys leading to zeroization. With it zeroization capability and the private key, Java Ring is one of the least counterfeitable devices. It will destroy itself rather than reveal its secret when tampered.
