Post a code where people need help. Someone scans it, a channel gets the request, whoever is free takes it.
A call point that costs a sheet of paper can go in fifty places. One that costs a tablet goes in two, and the two are rarely where the problem happens.
The scanner opens a branded page in their camera browser. There is no app, account, message form, microphone prompt or location permission between them and asking for help.
A member of the public has no channel key, so the request is deliberately kept outside member conversation history and labelled as an operational QR Assist event on both sides.
The nominated channel receives the request immediately in Console and on Android. An atomic claim means two people can tap at once without both believing the call is theirs.
Create a point in Console, assign its response channel and print the poster. The code keeps the same address until you retire it.
