Why free QR codes expire

Tool for this articleQR Code GeneratorOpen the tool →There are two kinds of QR codes. A static QR code holds the URL itself in its pattern. A dynamic QR code holds a short address that belongs to a service, and that service’s server sends people on to the real address.
Many QR sites make dynamic codes by default. They show you scan statistics, and when the trial period ends the short address stops working. That is why a QR code printed on a flyer stops working one day.
To keep using your QR code, make it a static one. The QR Code Generator on Dokkaebi Tools makes only static codes, and scans do not go through our server, so the code keeps working independently of this site.
