Can a QR Code point to a URL with a querystring?
The answer to that question is absolutely yes!
When you create a QR Code with our system, there is a field where you will enter the destination URL (example: http://interlinkONE.com).
If you need to append a querystring to that URL, you can absolutely do that. Simply include the value in the URL entry field, and then click to Generate your QR Code.
When someone scans the QR Code, they will be directed to the full URL that you entered.
