To extract part of the block data you need
NFCType=B
or
MIFAREClassic=B
, then identify
which data block to read, using settings with a
TagRead
prefix.
The following example extracts data in this way:
Example: Changes to
config.txt
to extract a fixed length of data from a particular start point
!VTAPconfig
MIFAREClassic=B
TagReadBlockNumber=8
TagReadKey=123ABC456DEF
TagReadKeyType=A
TagReadOffset=5
TagReadLength=4
TagReadFormat=d
Here you specify which block to read (with the key and key type to use, if needed),
the offset within the block to start taking data, counting from 0, and the length of
data to take. The output format is set to 'd'ecimal. So, in this case:
