Asos app allows shoppers to snap up fashion

"Ryan Gosling is my favourite actor so I'm going to look like him," says the Asos chief executive, Nick Beighton. "Here's a picture of Ryan looking cool so I'd like something to make me look like just like him. There we go, a printed T-shirt, add it to bag and away we go." Beighton is not waving a magic wand, he's demonstrating new technology that promises to change the way we shop. From seeing something you like to having a parcel winging its way to your home is now possible within seconds as new technologies reboot retailers' websites for the smartphone age.
