Have you noticed more and more of these little square symbols appearing in print media, storefront displays, and advertising signs? No, it’s not a bathroom tile nor a new-fangled crossword puzzle grid. QR (quick response) symbols are similar to barcodes but do more. They are scannable devices that allow readers, shoppers, pedestrians, restaurant and club patrons to use their late-model smart phones to access web pages, immediate-use coupons, and various other pertinent links. This article in today’s Tribune business section explains how these symbols are gaining popularity with marketers from the commercial/retail world as well as libraries, museums, sports teams, and other institutions.
