EDISON - Quick Response (QR) codes have been popping up in print, TV and online.

News 12 New Jersey's Tony Caputo spoke with several Hoboken residents who say they've been spotting and using the codes around the city.

A QR code is a two-dimensional barcode that is readable by dedicated QR readers, smart phones and almost any computer equipped with a webcam.
