QR code for the URL of the English Wikipedia Mobile main page, " http://en.m.wikipedia.org " Telephone directory with QR code on the cover QR code (abbreviated from Quick Response Code ) is the trademark for a type of matrix barcode (or two-dimensional bar code) first designed for the automotive industry in Japan. Bar codes are optical machine-readable labels attached to items that record information related to the item. It was initially patented; however, its patent holder has chosen not to exercise those rights. [ 1 ] Recently, the QR Code system has become popular outside the automotive industry due to its fast readability and greater storage capacity compared to standard UPC barcodes .
A QR code generator is a software or online application that allows you to create QR codes. QR codes are probably the most popular and flexible two-dimensional barcode that is used by most businesses and individuals for anything from their marketing campaigns, education and even in ordinary lives and lets not forget just for fun! As QR codes gain popularity, more and more Web sites are offering free QR code generator services. With all the choices, and because they are all similarly free, most people just use the first QR code generator they find. But how do you distinguish one service from the other?

Though apparently they’ve been big in Japan for quite a while , I first learned about QR Codes only last summer after seeing them used in the campaign for the Sci Fi film District 9 . Seeing this got me to wondering – Can you customize QR Codes with your own design features, logo or brand identity? Well, it turns out you can.
DIAMONDS and valuable works of art could be protected against theft using a microscopic barcode that stores encrypted information about the provenance of the items, making ownership easy to prove if they are stolen. The barcode, which takes the form of a cube 30 micrometres across, is being developed by a team at the National Physical Laboratory (NPL) at Teddington, near London. The cube is made of silicon coated with a 100-nanometre-thick layer of polymethyl methacrylate, a transparent plastic. It can be attached to hard surfaces using adhesive, or woven into the canvas of paintings. To create the barcode an electron-beam lithograph drills 90,000 small squares into the plastic coat of each face at five different depths.

For years bar codes have been promoted as a machine readable licence plate. Each label contained a unique serial number coded in black and white bars that was a key into a database containing detailed information. That was the expert wisdom. Yet many end users wanted to code more information. They wanted the bar code to be a portable database rather than just a database key.
A brief explanation of 3D barcodes - what they are and how they are used. In recent years manufacturing companies have been trying to implement a barcoding system similar to the barcodes for purchases and the retail industry. The only problem is that in manufacturing there are high temperatures, extremely solvents being used, as well as a wealth of chemicals and processes that inhibit the use of a label with bars on it. The manufacturers need to identify individual parts and not just the entire batch as it has been done for years. They wished to improve their inventory and tracking system - and have done so through the use of 3D barcodes. 3D barcodes use the same basic principle as linear and 2D barcodes.
The popular link shortening service Bit.ly (which has billions of clicks on its links per month) has just announced that it will allow users to shorten links and automatically turn those links in to QR codes which will lead back to the original link. This is a fantastic use of technology and I can already see tons of uses for this and it really shows that QR codes are going to become more and more popular and widely embraced. All you have to do to add a QR code to your URL is change the end of the bit.ly link to .qr and it generates a QR code automatically. The image on the left is one I generated in a matter of seconds How Does It Work And What Is The Future?
