OPENCARD DEVELOPMENT IN INDIA
Opencard
The OpenCard Framework (OCF) is a smart card middleware implemented in Java. The framework allows a smart card aware application to access contact and contactless cards that implement commands using Application Protocol Data Units (APDUs) as defined by ISO/IEC 7816-4, -8 and -9.
The OpenCard Framework was orginally defined by the OpenCard Consortium, but mainly driven by IBM and Gemplus. The work ended with version 1.2 of the specification and a reference implementation by IBM. The consortium split up and left the OpenCard Framework in a dormant state. The website was still available until 2007 and is now shut down. The original code was transfered the a project on SourceForge, but never actively maintained.
Opencard Architecture
The architecture of the OpenCard Framework is made up of the CardTerminal, the CardAgent, the Agents and/or applications that interact with these components. OpenCard consists of four Java packages with the prefix opencard:
- Application
- IO
- Agent
- Terminal
User Interaction
Using a smart card requires interaction with the user -- for card-holder verification. The interface User Interaction provides for this functionality. It provides methods to write a message onto the display and receive input from the user. Card terminals that do not support all user interaction features can make use of the UserInteractionHandler, which implements a UserInteraction as a graphical user interface based on the abstract windowing toolkit (AWT).
