Great tip on the "clean collar".
Around here (greater Milwaukee-Chicago) they've had bar codes for a while. Due to my previous explanation I actually have 3 gas suppliers, but because of my location, I still don't have to travel very far, only to remember where I'm going with that particular tank(s). Some docks use the reader, some don't. I can see where a bar code can speed up the refilling process as it could instantly read empty wt and DOT date, etc.
