Patent ID: 8554795

Claim:
A method utilizing at least one computer processor for writing data, via a write/read station, into identification media, the method comprising: assigning the write/read station to the identification media, wherein a first identification medium IM-X being of a different medium type from a second identification medium IM-Y, and each identification medium comprises an application area App-Ar freely accessible to applications App, with a plurality of application access keys RKi, RKj, and a plurality of access rights ACi ACj for part areas Bi, Bj of the application area App-Ar, initializing a file system FS for each identification medium, which corresponds to a defined, virtual reference file system RFS which is independent of the identification medium, the initializing performed such that all of the plurality of access keys RKi, RKj are replaced by a file system key FSK of the assigned write/read station, and all of the plurality of access rights ACi, ACj of the part areas Bi, Bj are disabled, and subsequently, writing the file system FS, in accordance with a identification medium being initialized, into the part areas Bi of the first identification medium and into the part areas Bj of the second identification medium, and thereby defining a file system starting point in each of the first identification medium and the second identification medium, wherein the file system starting point being defined in the assigned write/read station corresponding to the virtual reference file system RFS, so that any applications App(RFS) defined according to the virtual reference file system RFS are written into each identification medium via the assigned write/read station, and executed subsequently to the writing being successful, the file system FS is divided into a file system header FS-H and into a file system application area FS-App-Ar, or that the file system starting point FS-S lies in the file system header FS-H, and with the file system key FSK, access is allowed only for the file system starting point FS-S or the file system header FS-H.
