Editor's Note: QR Codes Are Big in Texas

A session led by Doug Mack, CEO of the private online sales site One Kings Lane, discussed Sears' QR code application that allows consumers to snap a picture of a QR code on a merchandise label to find out deeper product information about that merchandise.

Commenting on the application, Mack said: "This is a really big deal because it solves real-world customer problems. It allows customers to have the resource of the best merchant in the company, and ask for their opinion. The technology can of course be augmented by knowledgeable staff in-store, as well. Soon this technology will include payment functionality so customers can bypass checkout lines. It's truly transformative technology."
