The open source Java Card technology, first introduced by Sun in 1996, has also been enhanced in this new version to increase the interoperability of applications on smart cards from different vendors, the company said.
The Java Card technology is designed to securely store personal data on cards that are generally the size of a standard credit card. According to Sun, there are already 200 million smart cards in use worldwide for functions such as financial services, government, personal identity, telecommunications and e-commerce.
Remote Method of Invocation makes designing applications an easier process for developers by allowing the Java technology to work with both the smart card and the smart card terminal, Sun said.
The updated version of the smart card technology also has increased support of wireless standards, and the technology also has additional cryptographic algorithms AES (Advanced Encryption Standard) and elliptic curves to bring more security options to the software.
Java Card version 2.1 applications do not need modifications in order to work with the technology version 2.2, Sun said.
