Manual Datafox ZK-MasterIV
Mifare
Mifare is organized in 16 sectors at 4 blocks each (each per 16 Byte). Each forth block is used to encrypt
the data on the transponder. It is partitioned into a key-A and a key-B and contains a password (each
6 byte long) for write- and read permission as well as the access condition, the media types are defined
in. Depending on the application, all blocks of a sector can be available either in default-format (i.e.
the key-A is the read- and write protection key) or in data- or rather value-format (i.e. the key-A is the
reading password and the key-B is the master key for reading and writing). At the moment the Datafox
devices (up to version 4.1.4.xx) support only the default-format.
Legic
Legic is used only in the German speaking areas. Both spanned and unspanned memory cards are pro-
vided. On the unspanned memory card the data are read by means of position- and length indication. It
is impossible to write on such memory cards.
On the spanned memory cards you have to set not only the length but also the segment, the data are
read from.
iButton
iButton is a contact reading system. The iButton has only a serial number, which is read, when a contact
between iButton and transponder takes place.
