For the purpose of this article, the term Java Card denotes a Java Card technology-enabled smart card. Java Card technology allows applets written in the Java language to be executed on a smart card. It defines a Java Card Runtime Environment (JCRE) and provides classes and methods to help developers create applets. Applets run within the JCRE. The JCRE and APIs are modeled after the smart card specification When a Java Card is inserted into a card acceptance device (CAD), the CAD selects an applet on the card and sends it a series of commands to execute. Each applet is identified and selected by its application identifier (AID). Commands such as the selection command are formatted and transmitted in the form of application protocol data units (APDUs). Applets reply to each APDU command with a status word (SW) that indicates the result of the operation. An applet can optionally reply to an APDU command with other data.
JUST TO GIVE THE IDEA OF JAVA SMART CARD.

Suresh -
Did you take that information from somewhere or is it original material? If it's from another source, could you post the link, so everyone can check out the entire article.
Thanks -
Chris
