Yes, if you have created a Dynamic QR Code, you'll be able to edit the information linked with it anytime you want, without having to change the QR Code. This means that you will not have to re-print your QR Codes every time you make a change in the content.
You can edit the information by going to My QR Codes section of your Dashboard. You will have the option of editing the contents, as well as modifying the 'Advanced Settings'. Just make the required changes and click on Apply. You can also edit the name and the tags of the QR Code using this section.
Please note that only the content is editable and not the 'Dynamic URL' or 'Redirection URL' that is generated while creating the QR Code, as that information is hard-coded in the design of the QR Code.
