The Java Card Specification specifies a framework suitable for most tasks that interface with ISO-7816 protocols. However, this framework limits Java Card applets to only handling tasks that are supported by this protocol. Tasks such as physical security, using the standard Wiegand protocol, cards which test ISO-7816 card renders by pushing the limits of the protocol, and applications that depend on interfacing to different communication mechanisms, such as full duplex serial, USB, TCP/IP, or Bluetooth are among the many applications that cannot be handled within the Java Card Framework. In this paper we describe an approach that maintains backwards compatibility with the current Java Card framework. while enabling applications a means to escape from some of the constraints of the framework when necessary.
