The code to left is known as a Quick Response Code, commonly referred to as a QR code. The information-bearing squiggly lines are also referred to as Smart Tags or 2D Codes.
Many industries are beginning to incorporate these codes into their marketing, using them as a form of unobtrusive communication, by linking the QR codes directly to a url.
Mesob Ethiopian Restaurant is one of the first restaurants in the country to use these codes in their restaurant. Vickie Smith-Siculiano, Director of Marketing for Mesob, and her mother Debi Smith have created and placed information bearing QR codes throughout Mesob.
