MF3ICD21, MF3ICD41, MF3ICD81
Description
returns the File IDentifiers of all active files within the currently selected
application
gets information on the properties of a specific file
changes the access parameters of an existing file
creates files for the storage of plain unformatted user data within an
existing application on the MIFARE DESFire EV1
creates files for the storage of plain unformatted user data within an
existing application on the MIFARE DESFire EV1, additionally supporting
the feature of an integrated backup mechanism
creates files for the storage and manipulation of 32-bit signed integer
values within an existing application on the MIFARE DESFire EV1
creates files for multiple storage of similar structural data, for example,
loyalty programs within an existing application on the MIFARE DESFire
EV1; once the file is filled completely with data records, further writing to
the file is not possible unless it is cleared
creates files for multiple storage of similar structural data, for example,
logging transactions within an existing application on the MIFARE DESFire
EV1; once the file is filled completely with data records, the MIFARE
DESFire EV1 automatically overwrites the oldest record with the latest
written one (this wrap is fully transparent for the PCD)
permanently deactivates a file within the file directory of the currently
selected application
