Manuel Martinez, the manager of a popular salad restaurant in Washington, D.C., called Sweetgreen, assists a customer. Martinez says customers use the QR code on the wall to learn about promotions and to get discounts.
If you drive by billboards or flip through magazines from time to time, you may have noticed pixelated squares popping up all over the place. These aren't scrambled checkerboards or alien landing pads, but QR codes, short for quick response codes.
The codes are scanned with a smartphone camera, kind of like one might scan a bar code, and marketing departments all over the country are coming up with clever ways to use them.

For the first time, living people will be eligible to be honored on U.S. postage stamps.
The U.S. Postal Service announced Monday that it is ending its longstanding rule that people cannot be featured on stamps while they're still living. It's inviting suggestions from the public on who should get the first stamp.
"This change will enable us to pay tribute to individuals for their achievements while they are still alive to enjoy the honor," Postmaster General Patrick Donahoe said in a statement.
