@nikolal @marc0janssen @resist1984 Briar is excellent, and it no longer required scanning QR codes. From my review:
"7/7/2019- Update: You can now add remote contacts by exchanging Briar URLs. In the contacts list choose the "Add contact at a distance" option and enter the Briar URL of your remote contact which they will need to send you via another channel. This is also where you will see your own Briar URL to send to others."
