Walmart and P&G Do QR Codes Right
mobile stores inside 50 Toronto bus shelters. The idea is that people can use their time waiting for the bus more productively by getting some shopping done via QR codes. The way it works is that inside the bus shelters there are special posters featuring popular everyday products from P&G brands like Pantene, CoverGirl, Pampers, Gillette and Tide. All waiting bus riders have to do is download the QR-code app that links to Paypal, scan the QR codes for the products they want, confirm payment and then the goods are shipped for free.
