Well, the barcode units I have also have a version that is a long distance
scanner. They include a spot beam for aiming the scanner and can scan from
6 ft away. You don't think it's possible to hit a runner from 6 ft if you
Had a few seconds to spot beam the target? You could make the barcode
As wide as the runner's sign, about 1 ft? Sounds like we need sniper
training for special event volunteers...

I think this is a great discussion and there are some great ideas
here, but I can't see barcodes working for runners. I don't think it
would be possible (or at least not reliable) to scan the barcode of a
moving runner and there is no way they are going to slow down or stop
just so you can scan a barcode that is somehow attached to them.
For slower moving objects in an event, this makes sense, but I don't
see it working for rapidly moving runners in a marathon.
For runners, how about a keypad and manual entry of their runner
number as they go by? It is not as accurate as a barcode and some
might get missed if a big bunch goes by at one time, but it would not
impact their concentration. The missed ones would likely be caught
and logged by the next checkpoint.
