NFC pass, which is ready to work with the default configuration of your VTAP50 module. 1. Obtain an OriginPass from Dot Origin by visiting https://originpass.com/VTAP/ and add it to Google or Apple Wallet. (You will require a username and password - contact vtap-support@dotorigin.com to get these.) - Page 21 .pem format, where # is replaced with a number from 1 to 6, matching the key slot you will save it in. (The demo passes are accessed using the key in KeySlot 6, so don't overwrite this one unless you are finished with Dot Origin demo passes.) Note: A VTAP reader cannot use more than 6 private key files.
- Page 22 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).
