Swedish IT entrepreneur Robert Ilijason shows how to use a cell phone to scan a purchase at the no-staff, app shop in the southern Sweden village of Viken in this photo dated Jan. 27, 2016. Customers to the new general store need to register and download a cell phone app, then customers simply use their cellphones to unlock the door with a swipe of the finger and scan their purchases then they get charged for their purchases in a monthly invoice.
