Abstract
A smart card-based information processing system capable of compatibly operating under a standard requiring the complete processing of one command at a time, but which is also capable of queuing commands received from applications external to the smart card that it cannot immediately process. When the smart card receives a command that it can process immediately, it processes the command and returns an appropriate status response word. When the smart card receives a command that it cannot process immediately, it places the command in a command queue and returns a status response word indicating that it cannot immediately process the command, along with an index/identifier defining the memory location of the queued command in the command queue. If the smart card also has data or other information developed as a result of executing a previously queued command, it transmits an appropriate proactive command to the application, so that the application can send a command to request the information.
