It may look like black-and-white squares, but it's ultimately a personalized message to tweens/teens from their idol, singer Nick Jonas.
When scanned, a QR code on the back of cartons gives moms a message to buy Quaker Chewy Granola Bars so they can "Send your kids a custom message from Nick Jonas!"
Another code, this one a text code, is printed inside each box. By entering the text code at www.chewysuperstar.com/nickgreetz, parents, or whoever is entering the code, can create one of three free StarGreetz e-cards. The Happy Birthday, Good Luck or Congratulations e-cards are sent to the kids from Jonas and include the recipient's name.
They can then post the e-cards on Facebook.
