Mobile Commerce Minute Episode #305:
Seems simple enough no? An Edmonton, Canada (yes!) boutique retailer called Lux found out how to succeed with in-aisle payments when they recently introduced it inside their store. The key was to have a busy store and long checkout lines. Take those two factors and add the ability to download an app, pay where you stand and walk out instead of waiting in said long lines and success was had. A simple but valuable lesson on how/when/where to begin with this type of offering.
Canadians eh? We are smarter than your average bear.
