I don't think I fully understand what this is - a paid link shortener that generates QR codes?

I tried signing up but didn’t get an email.

I respect the simple page design, but what is a dynamic QR code and what service are you providing?

The ScanCity logo does not scan with the Google camera like a normal QR code.

The front page of this website is almost comically uninformative. I'd take this post down, update the site to explain itself better, and submit it again at a later date.
