3.3 Extract only part of the pass data
By default the whole pass data payload will be sent, using
KBPassMode=0
, but you can
choose to send only part of the pass data, by setting values in
config.txt
.
Note:
The examples in this section use the
KBPass
prefix on all of the parameters, to control
the behaviour of mobile pass NFC data being sent as a keyboard emulation. The same
parameters work in the same way with prefixes such as
ComPortPass
or
WiegandPass
to
control the mobile pass data sent over those other interfaces.
To extract only a part of the data use
KBPassMode=1
. The following examples extract data
in different ways:
Example: Changes to
config.txt
to extract a fixed length of data from a particular start point
!VTAPconfig
KBPassMode=1
KBPassSeparator=|
KBPassSection=2
KBPassStart=5
KBPassLength=10
Here you specify which section separators to find, and count sections and characters
from 0, to extract the right data. In this case:
