4.2.11 Write Value (0x0B)
Table 4.11
The Write Value command takes as an argument the address of the block where to store the value (Block Address),
the signed 32-bit integer value to be stored (Value), the block address value to store in the memory block (Stored
Block Address), the Authentication Key Number and (optionally) the Authentication Key. This command has the same
functionality as the Write Block command, except that it treats the block as a special Value type as defined by the
Mifare standard. It tries to format the block content to this 4-byte signed value together with the address on the last
4 bytes of the memory.

Argument Description
Address of the block in
the memory to where
the value is to be
written. The block will
be formatted as a value
type block after
writing.
Signed 32-bit value
that is to be written to
the value block. The
least significant byte is
stored first.
8-bit unsigned value to
be stored in the last 4
bytes of the block
memory.
The 6 least significant
bits (bits 0-5) define
the Authentication Key
Number from 0 to 39
to be used to encrypt
to be used to encrypt
the data. If the most
significant bit is set (bit
7), then the key will be
used as Key B, if clear
then the key will be
used as Key A. If bit 6
is set, then the key will
be taken from the
following argument list
(next 6 bytes).
Optional parameter
used when bit 6 in
Authentication Key
Number argument is
set. This Key will be
used as Key B if bit 7 in
Authentication Key
Number is set or as Key
A if bit 7 is not set. The
byte order is the least
significant byte first.
