Using red laser on an iPhone no luck. QR codes from Google Charts scan fine with the app.
Hi, I outputted the QR code using this gem on my macbook pro 13, used iPhone 4 and Nexus One with various scanning apps I could get my hands on for free and all of them worked.
Saved the png on my iPad and it works too.
Are you still having this issue? Would like to know what might have caused it to not work for you.
I was having the issue with using SVG, decided to use google charts for this particular project.I'll try the png next time around and let you know. Thanks for the help.
You should try to increase the :offset.
There should be a default :offset as it's required by the QRCode specifications, the code won't read without it.
