I have implemented qr codes or quick response codes on every post. Scanning these codes with take you to the page on which you scanned it from. If you have a smart phone you can scan the code and go to that page. I will give a mobile based version of the post.
What is a QR Code: Wikipedia’s Description
A QR code (abbreviated from Quick Response code) is a specific matrix barcode (or two-dimensional code) that is machine readable and designed to be read by smartphones. The code consists of black modules arranged in a square pattern on a white background. The information encoded may be text, a URL, or other data.
Common in Japan, where it was created by Toyota subsidiary Denso Wave in 1994, the QR code is one of the most popular types of two-dimensional barcodes. The QR code was designed to allow its contents to be decoded at high speed
The technology has seen frequent use in Japan and South Korea; the United Kingdom is the seventh-largest national consumer of QR codes
Who owns qr codes. QR codes is free of any license. Though denso wave owns the patent rights on QR codes, but has chosen not to exercise them.
