New barcodes can help you find your lost dog

This week my goal in writing this column is to give readers just a little background for the technology of the ever-more-ubiquitous “QR Codes” which are popping up everywhere. 

Quick Response Code (abbreviated QR code) is a type of matrix barcode first designed for the automotive industry in Japan.  A QR code consists of a square populated by smaller black squares on a white background.  With the right tools using QR codes is a snap (no pun intended).  A tablet or smart phone equipped with a camera and a QR code reader/scanner application feature is all you need to grab any QR code you encounter.

Some readers by now are probably asking what is the point?  This may be a fad today but there are some new technologies coming that may result in QR codes becoming central to every computer user’s online experience, so I hope that even readers without a smart phone will still read this column through to the end.
