QrCode are barcodes that represent text, url, mail addresses... Mobile phones as iPhone, Android Phone (google) can read QRbarcode to open widget, websites...
It's very simple to use, you only have to point mobile phone with camera on barcode. Mobile phone will detect barcode, read it then it try to use it to do action.
It's really usefull for bloggers or for widget developpers who want to give an easy access of them blog tickets and/or widget to mobile users.
"QRcode by Metal3d" generator is an easy system to add qrcode of your webpage, blog ticket, etc... You could use 2 solutions:
You only have to use this code in you blog, tickets, etc...
<script src="http://qrcode.metal3d.org/generate.js" type="text/javascript"/></script>
And that's all !!! For example, on this page, it produce: Ok ?
If you need to specify url to point, use this type of code:
<img src="http://qrcode.metal3d.org/?encode=URLENCODED" alt="The title you want"/>
This produces QRCode that points on URLENCODED you specified. It's very necessary to encode url. You can use php function "urlencode()" to get standard url encoded string.
For example: url "http://www.google.com" becomes "http%3A%2F%2Fwww.google.com":
<img src="http://qrcode.metal3d.org/?encode=http%3A%2F%2Fwww.google.com" alt="The title you want"/>
That produces:
There is watermark on barcode. It' simply because I spent a lot of time to create this qrbarcode encoder...
You are not allowed to remove this watermark, please let it at bottom of qrcode to let your users to know how you get this barcode.
If you really want to remove this watermark, please contact me at
