QR Code: Documentations & Download 2.0.2
This pluging helps you encode your information into QR code.
QR codes are a popular type of two-dimensional barcode. They are also known as hardlinks or physical world hyperlinks. QR Codes store up to 4,296 alphanumeric characters of arbitrary text. This text can be anything, for example URL, contact information, a telephone number, even a poem! QR codes can be read by an optical device with the appropriate software. Such devices range from dedicated QR code readers to mobile phones.

Hi Max,
Just tried installing and running the plugin. I think there might be a syntax error in the code you show above. You have type=” with just one quote there. I’m guessing that’s not correct?
Anyway I tried this in a page :
<img src="{exp:qr_code tel="01213121212" data="ExpressionEngine" title="Test" email="me@me.com" subject="Test"}" alt="QR code"/>
and in the source of the page I get this :
<img
Also should sabj (shown above) be subj or subject in the parameters?
Sorry Max, have it sort of working now. You’re missing the end tag on your code above 
How do you change the size of the image to make a much larger QR image? I see the size parameter above but not too sure what to place in there?
Best wishes,
Mark
Aha!! Just tried a number instead and that works!!!
You have PNG:4 above which was confusing me
Off to see if it works on my iPhone now.
Best wishes,
Mark
Thanks Mark for comments! 
Part of this is my misprinting + EE forum tags eating.
Everything is fixed now.
Regarding “sabj” - it is really dumb mistake from my side. You can download new build from QR Code addon page.
Sorry for taking more your time that its needed.

Absolutely no problem at all. As mentioned on Twitter I’m just exceptionally grateful to you for all you give out for free and your coding is fantastic.
Keep up the fantastic work I say.
Best wishes,

Hi. I think my code is correct but for some reason I can’t get the px_color to change from 000000 to ff0099…
<img src="{exp:qr_code type=" action="site" data="{property_qr}"color="ff0099" ecc="M" size ="2" title="{property_title}" alt="QR code"/>
My bad, px_color setting was related to bk_color by mistaken (works only if you have bk_color too). The update is available now.
<img src='{exp:qr_code type="" action="site" data="{property_qr}" px_color="ff0099" ecc="M" size ="2"}' title="{property_title}" alt="QR code"/>
p.s. don’t forget to delete your cache files from images/cache/
Thanks! I won’t. Yes, very much. I did, hope it’s enough.
Thanks bj - this is more than enough . Glad to hear that QR code helps you.
