I used the SCAN app exactly once about a year ago and loved it. However it only worked that one time. Every other time it could not connect. It was truely great, it put so much trust in you. Self-checkout stations don't let you remove items, but this app let you edit the cart as you liked. Scanned something twice, not a problem. Put something back? just remove it. Checking out was a 30second task, and it did feel a little weird. I had a whole cart full of stuff, scanned my phone, paid, and left. I put a lot of care into making sure everything was there and accurate, but I can see how easy it was to abuse. Easily could have not scanned half the things in there. An interesting thing was that it didn't actually save much, if any, time. Maybe even took sightly longer overall. Scanning with the phone every time you added something means pausing in the store to do it, switching between scan mode and shopping mode wasn't seamless for me. Putting something back after you scanned meant fiddling with your phone for a little bit. Maybe if I was able to do it more then once it would have become significantly faster.
