Form

If the page or post contains a form, you need to add the attribute form=1 to the shortcode:

[dynqrcode auth=33 form=1] ... [/dynqrcode]

If you have selected "Request method and custom field in form" in the Form check mode under Settings, you have also to add an hidden HTML input filed to the form:

<input type="hidden" name="dynqrcode_auth" value="33">

You can find the copy-and-paste HTML code in the QR-Code Edit page.

This way...

users who scanned the QR code enhanced image will see the content enclosed in the shortcode.

To improve the security, enable the QR code scanning only to MyFast APP applications.

How to use the standard image

If you wish to use the standard version of the QR code image you need to check the Enable content hiding with standard QR code image option of the Settings page.

Warning

The content hiding procedure is not hacker proof.

Do not hide sensitive data a/o crucial information.
