Who says waiting for the subway has to be idle time? Rather then fiddling with your smart phone with that glazed look in your eye, why not use it to get some grocery shopping done?
South Korean supermarket chain Home Plus has developed a trial run of a virtual grocery store that allows commuters to restock their kitchens on their way to work.
WIDE ANGLE: SMART PHONES
Home Plus plastered subway stations with replicas of groceries that are labeled with a unique code for each product. As they pass by on their way to work, commuters can use a mobile-phone app to snap photos of desired products, then check out. Groceries are then delivered to their doorstep by the end of the work day.
