Let’s say you work in a museum and you are looking to place a QR-Code next to every artifact that allows users to scan and learn more about that artifact. This could be achieved by creating a QR-Code containing a URL which takes the user to a mobile friendly version of the musuem/artifacts website.
Question
But, what if you need to change the URL contained within the QR-Code? How could this be achieved without changing the QR-Code itself?
Redirects
Well, you could consider making use of a redirect (commonly known as a URL forwarder).
First, create a vanity URL such as:
http://www.example.com/artifact-a/
Then have your web developement team have it redirected too:
http://www.example.com/indian-heritage/
Using our nifty QR-Code generator, create a QR-Code with the URL/redirect that you created and plan to manage e.g. http://www.example.com/artifact-a/
You could then place the QR-Code containting the redirect wherever you like. If your desired destination of the webpage or URL changes, you can then alter the redirect to reference the new webpages location; we have not changed the URL in the QR-Code, just the destination it redirects too thus solving our conundrum.
