Step 2: Declare Merchant ID(s)/Collector ID(s) in the
config.txt
file
1. Open the file
config.txt
in a text editor (such as Windows Notepad). It already
contains parameters for accessing the demo passes, prefixed
VAS1
and
ST1
, both relying
on KeySlot 6. You can overwrite these, or keep them in addition to your own pass
reading parameters.
2. Add your pass reading parameters in the
config.txt
file to access up to 6 Apple
VAS and up to 6 Google Smart Tap IDs, and identify the keys to be used in each case.
Note:
Although the VTAP100 supports multiple IDs, Apple and Google expect most
users will only use one. Using multiple IDs is an advanced feature to use with care. The
VAS# and ST# numbers define the order in which IDs will be requested from Apple or
Android phones respectively. The lowest numbered ID will be requested first, then
continuing in ascending numeric order.
Put each parameter on a new line. Order of parameters does not matter to the
VTAP100, but could help other people who need to edit the file. Start any comment
lines in the
config.txt
file, that the VTAP100 should ignore, with a semicolon. Each
parameter should only appear once - if it accidentally appears more than once then only
the last instance will take effect.
Example: Settings in
config.txt
to interact with both
Apple VAS and Google Smart Tap mobile passes
!VTAPconfig
VAS1MerchantID=<your merchant ID>
VAS1KeySlot=1
; This says use the key added as file 'private1.pem' to read and
; decrypt any pass connected to your merchant ID on an Apple iPhone
ST1CollectorID=<your collector ID>
ST1KeySlot=2
ST1KeyVersion=1
; This says use the key added as file 'private2.pem' at key version 1
; to read and decrypt any pass connected to your collector ID
; on an Android phone
3. Save the amended config.txt file and these changes will take effect immediately. (A small
number of changes to the
config.txt
file require a reboot to take effect, for instance
to the status of the virtual COM port, but these are highlighted in later sections).
