QR Code. QR code for the URL of the English Wikipedia Mobile main page, " QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte / binary, and kanji) to efficiently store data; extensions may also be used.[1] The QR Code system became popular outside the automotive industry due to its fast readability and greater storage capacity compared to standard UPC barcodes. Applications include product tracking, item identification, time tracking, document management, and general marketing.[2] History[edit] The QR code system was invented in 1994 by Denso Wave.
Standards[edit] There are several standards that cover the encoding of data as QR codes:[5] Uses[edit] URLs[edit] QR Code Generator. Create and manage QR codes with easy. 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!
They’re widely used by any web design agency 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? How can you be sure that you are using the best QR code generator there is? 1. The best thing about QR codes is that it can contain a lot of different types of information behind it. 2. 3. 4.
This would come especially handy when you are putting up the generated code solely on your Web site. 5. A QR code generator should make your life easy.

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. Pretty easily. At least up to a point. While researching the topic, one of the earliest examples I could find of someone hacking a QR Code with their own branded design elements was Duncan Robertson from the BBC. The key takeaway I got from Duncan’s pioneering work was that QR Codes have some relatively generous built in error correction, up to 30 percent in some cases.
Now, what exactly does 30 percent translate into regarding how far you can push a QR Code before it breaks? QR Code created by Takashi Murakami for SET.

Hack. 3D barcodes to identify stolen valuables - tech - 30 July 2005. By Mick Hamer 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.
The technology has huge potential for storing information securely, says Cuenat. However, in practice storing information on the provenance of an object would not require anything like this capacity. Once in mass production each device will cost about £1. How to Make 2D Barcodes. 2-Dimensional Bar Code Page. 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. In 1984 the trend to portable databases began when the Automotive Industry Action Group (AIAG) published an application standard for shipping and parts identification labels which consisted of four "stacked" Code 39 bar codes. These stacked bar codes contained part number, quantity, supplier, and serial number. The first truly two-dimensional bar code was introduced by Intermec Corporation in 1988 when they announced Code 49. There are several terms now being used to describe this new class of keyless data entry symbologies. There are well over 20 different 2-D symbologies available today. 3D Barcode (Bumpy Barcode)
3D Barcodes (Direct Part Marking or DPM) 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. An image of some sort is applied to a product and then read by a device to log, categorize, inventory, or track an individual product.
As previously stated, the manufacturers need a more permanent solution than a label or sticker. The Kaywa Reader. Bit.ly Now Lets You Add QR Codes To Links In Seconds.
