A QR code (short for Quick Response) is a  matrix barcode (or two-dimensional code), readable by dedicated QR barcode readers and camera phones.

 

The code consists of black modules arranged in a square pattern on a white background. The images contain a message that can be unlocked by using an application on a smartphone.  The information encoded can be text, URL or other data.

 

Use of the codes started in Japan, but use in the US is increasing, offering up new opportunities for mobile communication.

 

According to a recent survey of smartphone users, commissioned by MGH to determine the usage of QR codes, 72% of smartphone users indicated that they would be likely to recall an ad with a QR code.
