U.K.-based startup Powa Technologies has developed PowaTag, a payment technology that allows consumers to purchase a product by simply taking a photo of it on their smartphone, making virtually any ad shoppable. Some of the most unique places for these shoppable ads have included bus stop windows and taxicab screens. 
The PowaTag platform combines technologies, including Bluetooth beacons, digital audio watermarks, QR codes and embedded social media links, to enable consumers to scan an image and purchase instantly via their smartphone.
