Abstract
There is provided an integrated circuit card having an associated operating mode. The integrated circuit card includes: a microprocessor; a memory coupled to the microprocessor; data stored in the memory representative of the operating mode; an operating system stored in the memory for processing selected information in a first IC card format; a shell application stored in the memory for processing the selected information in a second IC card format; and means for routing the selected information to either the operating system or the shell application responsive to the operating mode. The selected information may be a command, such as a file access command.
