The QR Code with a Voice

Roger — Wed, 02 Apr 2008 14:35:20 +0000

The advanced QR Consortium in Japan have launched their VoiceQR website. VoiceQR is a way of encrypting a small amount of voice or music into a QR Code. Sound is in AMR format, a compressed audio format developed by Ericsson and used by many mobile phones for voice recordings such as MMS messages. Currently limited to two seconds of audio and available on only seven mobile handsets it will be interesting to see how consumers react to the new technology.

Wickd are selling a range of T-shirts with a ShotCode logo on the back. The proprietary two dimensional barcode is unique for every product and is linked to the user. You can link your code to any url such as your own mobile site, your MySpace or Facebook homepage etc. If you use your Wickd profile you can even exchange private messages. The only negative is that ShotCode, unlike QR code, is not open source and is not so widely used internationally.

Facebook Add to Friends QR Code

Roger — Wed, 20 Feb 2008 22:20:31 +0000

A new facebook application has just been launched called Add to Friends Shirt which creates a shirt that lets people get in touch with your facebook persona via a QR Code. In the application the facebook user clicks on ‘Make a shirt for me’. The QR code for the url of the user’s mobile facebook page is generated on the fly and then reproduced on a Zazzle page where they can order a variety of shirts with the QR Code printed on the back.

IT DeSign’s Design QR agency provides QR Code production and consulting services from the International Fashion Center building in Tokyo, Japan. Their latest idea is to embed a QR Code in… well, another QR Code. They have called it double QR and you can read the relevant page on their website with Google’s translation from the Japanese here.

Sergey Odinokov, IT Department Director of the Rubicon Group emailed to say that iMatrix has developed the first 2d barcode recognition software for the iPhone. (Also see later post iPhone, QR Code, Datamatrix and now ShotCode)

There are also a couple of interesting application on their Website. One where you can generate QR codes for Google search results and another that produces QR codes for tag clouds.

Sergey says keep an eye on iMatrix because integration with proprietary formats and resolution services is imminent.

QR Code Firefox Extension

Roger — Sat, 19 Jan 2008 11:36:23 +0000

Snapmaze have created a Firefox extension that allows you to generate a QR code for the URL of the page being viewed. It’s a nice idea but slightly spoilt by the over-size window that opens to display the QR code and the Google ads shown below the code. You can download the extension here - Snapmaze Firefox Extension.

Google has announced a multi-format 1d/2d barcode reader.

ZXing (pronounced “zebra crossing”) is an open-source, multi-format 1d/2d barcode reader library implemented in Java. The objective is to support decoding of QR Codes, Data Matrix and the UPC family of 1d barcodes. It will provide clients for the Java 2 Platform, Micro Edition (J2ME), Java2 Standard Edition (J2SE) and Google’s open handset alliance project (Android).

QR Decoder

Roger — Mon, 01 Oct 2007 15:24:40 +0000

Jaxo Systems based in Montpellier, France is a developer of software for cell phones and PDA’s.

They have recently developed a barcode package which handles both linear and 2D barcodes including PDF417, Datamatrix, QR and Aztec. There is a demo on their website and you can generate any of these codes by simply selecting the appropriate options and entering your text.

Also on their website they have a QR decoder software download QR decoder which you can run on your PC. I have used it on a number of QR codes that I found on the web and I have yet to find one that it can’t decode. If you are running Microsoft Windows you will need to make sure that you have Java software on your machine. You can download Sun Microsystems free version here.

Also if you are running XP after you have downloaded the QR decoder you will need to click ‘Start’ and then ‘Run…’ before typing in ‘cmd’ to run the command interpreter. Once in the command interpreter just navigate to the directory where you placed the QR decoder download and follow the instructions given on the Jaxo website.
