Until very recently, however, all we cared about when it came to these clever contraptions was speed and accuracy. There were problems there that needed to be resolved before the category could progress, but if we were to call it, we'd say 2015 finally put these concerns to bed.

So, instead of droning on and on about how scanners facilitate mobile payments — a very intriguing advancement in smartphone technology, but rather played out now — we thought we'd round up 5 sensible features that manufactures could bake into them little cutouts.
