You are only a few steps away from the creation of your next high resolution QR Code:
The QR code is a brand of a specific two dimensional matrix barcode. It was created by the Toyota branch Denso Wave in 1994 due to the need for tracking automotive parts during the manufacturing processes. The matrix barcode is highly secure designed and can also be reconstructed if up to 30 percent of it has been destroyed.
In the meantime, QR codes are well established to present URLs, Telephonnumbers and whole contact data e.g. business cards on websites, image brochures, online and print advertisements. They are used by smart people who recognized that most user do not want to manually write and type any data. If you are looking at a qr code, just take your mobile phone and scan it with an easy click. No need to type anything, the software on your smartphone recognize the content and you will be asked what to do next, e.g. visit a url or safe the data as a new contact. With the QR-Code-generator i offer, everyone is able to create such qr codes and to publish them on any desired media. The qr code is able to hold almost the complete textual content of this website. A maximum of 4,296 alphanumeric characters can be stored within the code.
The encoded text and data is presented in a two dimensional quadrant with black and white dots. A two-dimensional matrix barcodes is able to store approximately 100 times more data than a common linear barcode. The maximum capacity of the encoded characters is over 4,200 alphanumeric characters (numbers, letters and symbols). You find more technical and historical information about it here: Wikipedia and here
Common QR Codes contains only black and white pixeldots. There are some special variants like integrated brands or logos within the matrix or multicolor codes with different colors, but a really new and extravagant creation is shown by Russ Cox at http://research.swtch.com/qart He explains how to convert a photo into a pixel matrix code and to embed it in a way that it looks like the image beside. There is a lot of content on his site, maybe you do not find the right link to the image QR-Code-Generator, so here it is: image qr code
For Android based mobile devices there is the great QR code and barcode scanner barcoo
The first software uses qr images or pdf files to decode the content of them. Just drag and drop into the software or open a qr code image or pdf and let the software do the full decoding. There is no need for a cam or smartphone. The software is called bcTester
Another way to check if a QR Code works when you do not own a smartphone is the webcam based software bcWebCam. Install the software and let your webcam do the job. Although the better qr code recognition is given by the first mentioned software bcTester you could give it a try nevertheless. Download here the bcWebcam
