What is a QR Code?

Read Wikipedia QR Code article.

Will there be a PHP4 version?

No. This plugin is based on OOP sytle which is not available in PHP4.
Please upgrade your PHP installation.

Does it work with PHP 5.3?

Yes it does.

Does it work with PHP 6?

I don’t know. Not tested yet.

Which image type should I choose?

PNG is the preferred one. If you’re concerned about very old browser, use GIF instead. Or JPEG.

Which code generator should I choose?

If you’re on a webserver that disallows online connection from within php scripts, you should switch over to the QR Code Lib.

There is a red image instead of the QR Code image. What’s wrong?

You’re /qr-code-tag/data/ directory is not writeable. Please adjust
your permissions. See Changing File Permissions.

How to use the tooltip mode?

See Plugin Help (below Plugin settings in your WordPress administration area).

There is only a blank page for large posts with your plugin! Why?

This is a PHP / WordPress problem. See Sudden empty / blank page for large posts with WordPress for problem description and solutions.

The margin with the Google API differs from that one created by the QR Code Lib. Why?

Google Chart API creates a different margin. I can’t tell you why – ask Google.

How I can check the generated QR Code?

You can use the Google ZXing online service

Where I can download a barcode reader for my mobile device?
The plugin is not available in (_put a language in here_). Why?

Because no one translated it yet. How about you? See Plugin Help for translation hints!

There source code format does not follow WordPress standards. Why?

This plugin obeys the Zend Framework Coding Standard for PHP
because the WordPress Coding Standard does not fit OOP, IMHO. Sorry Matt.
