Why do I get the scan notification always twice by e-mail, when I scan a QR Code?

We only send one message per scan per second. You will receive a scan notification as often as the link in the QR Code of is scanned from a mobile device. Some QR Code Readers request the link twice, this explains the double notification.

If you want a more accurate notification please use Webooks.
