We need to get new scanners. I'd love to hear any recommendations and revelations.
The Science Museum of Minnesota has been using the Motorola Symbol TC70 (Android) scanners for a couple of years now, and they've performed very well (and their battery life is still good!) We are on NScan 6.06 and Tessitura version 14.0.6. We used to use the MC70s (Windows OS model)- and our users (and I.T. support) have been very happy with the TC70s. The only minor complaint we've had was that there is this bright white light that comes on near the scanner cross-beams when the scan is triggered (in case there's dim lighting externally) - but if the scanner is pointed down at a ticket, for instance, it could be very bright for small children that may also be standing there. On this model, that light can't be disabled, so we've remedied that with a bit of electrical tape over the light, which doesn't interfere with the scan beams.
They are also solid on the wireless (if it's a good connection), but if they move between wireless access points - they may not 'hop' well and think they've lost connection to the server, so we put a dedicated Wireless AP near that main entrance so we don't run into connection issues (because the entrance was right in between 2 wireless APs that would too-easily cause a switch of connection).
Many of our scanning staff are Volunteers and retired, and they have had no complaints of functional use or visual impairments.
