QR Code Q & A

What is a QR Code?

Unlike a standard one-dimensional barcode, the type we see on books and products, a QR code is two-dimensional, meaning that the information changes
vertically as well as horizontally. A QR code reader scans up as well as across.
This enables a QR code to contain much more information than a barcode.
It also requires a more sophisticated reader, but you don't have to worry
about that. That's already been taken care of by software and hardware
engineers. You can download—at no charge—a number of very
sophisticated QR code readers for your mobile phone.

Who Invented QR Codes?s

QR codes were invented in Japan in 1994 by Denso Wave, a subsidiary of
Toyota. “QR” means “Quick Response”. Denso wanted a code that could
be decoded very quickly in order to keep track of a very large number of
items in their inventory. While the term “QR code” remains a registered
trademark of Denso Wave Incorporated, and Denso retains the patent on
QR code technology, it has released all of the information on creating and
scanning them so that they can be used by people all over the world at no
charge and with no obligation to Denso. You need no license to create or
use QR codes. It was a very generous act—and one from which you can
benefit. you can easily do it yourself at no charge.

because they're fun and useful. They like interacting with your
message and getting or learning something they couldn't get

In Japan, some people are putting them on tombstones. Visitors can then view a video about the deceased, or even a video  created by the deceased before death.
In the Netherlands, to celebrate its 100th anniversary, the Royal Dutch Mint has put QR codes on the backs of some gold and silver coins, which can then be scanned to visit a special website where you can play a memory game.
