QR Code Generator
This is based on Swetake's QR libs.
The following just adds more graphic formats, colourising and a smart resizer to match particular pixel sizes cleanly, only really matters when they are being printed quite small. Using the print button below will scale the QR Code to fill the current paper size.
Originally written when we were experimenting with QR Codes at Rix Centre as a means of system login for users who were unable to type or use a pointing device. QR Codes are still proving a very interesting approach for users with severe and profound ID, allowing for passive access as well as via manipulatives.
If you're working with similar applications of QR Codes, ReacTIVision is also worth a look both with QR and more easily recognised fiducials where camera focus is a problem. Rix Centre is currently developing applications based around ReacTIVision with severe and profoundly intellectually disabled people see: SymbolSurfing
