I ride the Keystone line (primarily a commuter line from NYC to PHL to Harrisburg PA) for work just about every day. My conductors got their devices a couple weeks ago. They're frustrated. Before the scanners, one of our conductors could cover about 2 cars' worth of passengers in maybe 8-10 minutes. Admittedly, being a commuter line, this gets easy because they start to know the names and faces of the commuters.
After the devices were introduced, a conductor's now covering about 1-1.5 cars' of passengers between stops. Sometimes it works on the first try, other times they'll try and scan tickets 3, 4, 5 times before giving up.
If I were doing a field research exercise with these conductors, I'm pretty sure my report wouldn't look too favorably on the scanners. Higher task time-to-complete, higher error rate leading to higher passenger miss rate (and possibly increased fares in the future), ergonomically questionable...many issues.
