2.2 Provide pass reading parameters and keys

storage device and list the files contained, including the main
config.txt
file.
To read any mobile NFC pass, you will need to provide your pass reading parameters. This means a
collector ID or merchant ID and any keys. These allow you to read and decrypt pass data that is held
by your users, on their smartphones.
First, upload any private keys needed to decrypt data, then edit the
config.txt
file items which
are prefixed either
VAS
for Apple devices or
ST
for Google Pay Smart Tap devices.
Step 1: Upload key file(s) to VTAP100
1. Ensure each of the keys you need to use are stored in a file with the name
private#.pem
,
following the .pem format, where # is replaced with a number from 1 to 6, matching the key slot
you will save it in.
Note:
You cannot use more than 6 key files.
2. Load your keys by copying these files onto your VTAP100 mass storage device.
3. When you reboot the device your key will be stored in hardware, and will no longer be listed as
a file on the device.
4. You can confirm key file(s) have been loaded when you
Step 2: Declare Merchant ID(s)/Collector ID(s) in the
config.txt
file
Add details in the
config.txt
file to access up to 6 Apple VAS and up to 6 Google Pay Smart Tap
IDs and identify the keys to be used in each case.
Note:
Although the VTAP100 supports multiple Smart Tap IDs, Android Phones using Google Pay
expect most users will need only one Smart Tap Collector ID configuration.
