Changing the URL of a QR code once QR code image in use

[Claire]

I wondered if anyone would be able to help. We have a QR code in use
throughout a campaign we are using and wanted to know if it is
possible change the URL of this existing code without having to
request a new one?

If so, how would we go about doing this?

This has been asked many times. You can of course change what is in the page that the URL refers to. But you cannot change a URL on the printed page any more than you can change a word on a printed page. This is why people usually encode a redirector URL, so they can change later what it redirects to.

Thank you for replying so promptly Sean.Very helpful.

For future reference is this an easy process to encode a redirector
URL?

Claire,

I believe you miss understood the point Sean was alluding to. If you have a barcode pointing to "http://a.b.c/something?123", just change the server to make that url "go" somewhere else. Dependent on the server software there are many different ways to do this, but the crux of the point is that you don't change anything on the barcode - as Sean said once it is printed you can't change it.

Use any public redirectors like goo.gl or bit.ly. Or roll your own.
Redirectors also allow the URL to be much shorter that enhances the
readability and error correction.

Most modern redirectors also allow directly a QR code for a certain URL.

For instance you can get a QR code for
http://goo.gl/l6MS
by appending a .qr at the end:
http://goo.gl/l6MS.qr

Same goes for the bit.ly, but append .qrcode to the shortened URL.

Lachezar,

Most public redirectors(URL Shorteners) don't allow you to change the associated URL after it's been created. AT&T offers a "create-a-code" service that allows you to create 5 free data matrix codes that you are allowed to mange the redirection at any time (requires using their scanner though at this time)

Also be aware that if you use a service like goo.gl and bit.ly that other people can see your statistics for the scans. In your example... http://goo.gl/l6MS.info will show how often that code has been scanned... for bit.ly, just add a + sign after the shortened URL to see the stats

My bad...

Indeed there are many services on the net that allow you to manipulate
(as others have described) the redirector.

The HTML code itself is simple. Here is one example:
<meta HTTP-EQUIV="REFRESH" content="0; url=http://yourwebsite.com/
index.html">
Hint: The zero means redirect without delay and is based in seconds.

You can also check the following websites that have this feature built
in and are free for low volume use.

http://uQR.me
http://GoBarcodes.mobi
http://QRstuff.com

There are many others to choose from. Some offer analytics and some
don't.

Hope this helps!

I think you're in the same boat as i am. I setup a QR code, not thinking about it... had it printed on some advertising material, then had the code shut down. The only way to get it active again is to pay monthly for the QR service. So the question is... Is there a way to take an existing QR code and have it redirected to my site, without having to subscribe and pay for the other service? Honestly it's cheaper just to reprint everything, but a total pain in the arse.
