I've been noting an interesting observation in the last few times that I have used QR codes in presentations is that some readers don't seem to be able to access the qr codes that I have generated. This was a surprise because I assumed that the QR code generators followed the QR Code - ISO standard (see http://en.wikipedia.org/wiki/QR_Code). Therefore, you could create a code in one generator and it would be accessible by all readers.
Therefore, in an attempt to unpick this I was wondering, if people have a QR code reader on their mobile device, could they download the QR Codes on the following word document (http://www.bath.ac.uk/lmf/download/23922 ). After they have tried to access them, could they please email me your findings (a.ramsden@bath.ac.uk). I'll write up the findings in a couple of weeks and share them.
Thanks :-)
I was able to read all the QR codes with a webcam and both Quickmark and
bcWebCam software. Codes 5, 6, and 9 (the biggest/most complex codes) were
the most difficult to capture.
My N95 (8gb model) was able to read them all and display the correct text
or link with the built-in Barcode software.
Great Question. Some friends and I have been working on a QR Code
generator and API and we have investigated literally dozens of readers and
tried to find all the possible encoding methods. By and large, the issue
is not the QR Code standard, but it is a problem with the encoding standard
(data embedded in the qr code that represents the action if scanned).
I been using http://www.beqrious.com to generate codes, I like this site :)
you can save the codes in a PDF format which helps me out!
