 A simple service for making QR labels with URL links that can be dynamically configured.
 
 ##Intended use
-A set of QR codes is generated and printed as generic link-labels. The labels are standard URLs and work with generic QR scanninc apps. The URLs point to the address of the qr-label server and provide a short, unique identification tag. When a label is scanned for the first time, the system allows to assign a link to that tag. Once the link is assigned, the service will always issue a HTTP 301 redirect on that unique tag, to instantly display the intended page.

+"Blank" QR tags are generated and printed in advance by the system administartor. Anyone holding such a blank tag can assign a link to it without any user account registartion. The codes not sequential, to discourage any attempts to "guess" a link. An administrator can view all created links, as well as edit them.
