Abstract

The claimed subject matter can provide an architecture that can transparently provide more robust interactions between a host device (104) and a smartcard or other mass media storage device (106) by way of block level read or write operations provided as part of a standard interface protocol. A virtual controller (110) can be installed on the smartcard to manage access to the data store of a smartcard. The virtual controller can provide special objects (112) (e.g., files, directories, partitions...) to the host, and upon an access (402) to one of these special files, call an application (208) to manage pre- or post-processing of the data transferred between the host and the smartcard.
