Abstract:
The claimed subject matter can provide an architecture that can transparently provide more robust interactions between a host device and a smartcard or other mass media storage device by way of block level read or write operations provided as part of a standard interface protocol. A virtual controller can be installed on the smartcard to manage access to the data store of a smartcard. The virtual controller can provide special objects (e.g., files, directories, partitions . . . ) to the host, and upon an access to one of these special files, call an application to manage pre- or post-processing of the data transferred between the host and the smartcard.

Abstract:
In a system for data exchanges without physical contact between a generally mobile portable set and a terminal or a population of generally fixed terminals, it is sought to make a modular set comprising a portable object (notably a memory card) that can be inserted either into a transceiver device, or in an ISO reader for by example, by saving on an interface management system and by reducing the power consumption of the set to the minimum. The transceiver device is without any microprocessor, and the portable object houses means for the management notably of the transmission/reception protocol of the portable set and of the ISO 7816-3 protocol.
