I wonder what the problem is. My little keyring card is tiny and scuffed and scratched and it scans the first time.
The Droid barcode is big and bright. Maybe too big? Maybe the scanners are calibrated for a certain size? Oh, well.
Tried it at two groceries stores and the gym. The grocery stores were flat bed scanners, but that's what you see most of the time in self-checkout lines. I had the brightness turned all the way down and had cleaned the screen before I tried to use it. Since no one was behind me I actually tried for quite some time, but no luck.
Really disappointing since I do have a bunch of cards in my walled.
