Dynamic QR Code – Changing the target URL

A QR code usually has a static URL encoded to which the user is redirected after he has scanned the QR code. In case the target URL is no longer up-to-date or does not exist anymore, you may use a dynamic QR Code instead. 

Dynamic QR Code

With the free QR Code Manager from qrd.by it is easy to change the destination URL. The URL in the QR code is always the same, but first redirects to our company website and after editing the target URL to this blog.

Create a Dynamic QR Code

With a dynamic QR code, you can change the target URL subsequently. Even if the QR code has already been printed on posters, flyers or in magazines, you can redirect the user after the scan to any landing page, anytime, without having to print the QR code again.

For instance, if you are using a QR Code to redirect the user to a temporary available voucher, you can change the target URL after the promotion has ended.

If you create a dynamic QR Code on our platform he will never expire!

    Hi Peter,

    Is there a way to have the url automatically changed via a trigger of sorts? I’m using a dynamic QR code that on first scan directs users to a registration page, but need it to be changed to another url with the same passing parameters once the user has registered. I know it can be done manually, but this comes with a time delay, user error, as well as it being a manual process.

      Hello Chris,

      Yours seems like a very interesting/smart case. I understand you want to use a QR Code to register the first time it is scanned and to login later on. Is it correct?

      There are a couple of possible solutions depending on the context:

      1 – Are you planning to use the same QR Code for all the users? If this is the case, you should base the business logic on placing a cookie on the users device. You can use our custom landing page solution from our platform.

      2 – Are you planning to use different codes for each user? Then you can use the 1-time QR Codes type that redirect a user to a special URL when scanning a QR Code for the first time. Each subsequent scan will redirect to the default URL. The problem with this approach is that if the user does not register the first time he cannot do it the second time. https://public.qrd.by/screenshots/QRD.BY_Support_-_2020-10-14_00-01-44.png

      3 – You can also explore our API https://qrd.by/api and webhooks https://qrd.by/webhooks and code a fully custom business logic.

    I need your help. I have printed a wrong qr code on my materials. Can you redirect it for me if I gave you the qr code?

          Hello Akhila,

          I’m Jordi Hernandez, Professional Services Manager at qrd.by.

          I’m afraid we cannot assist you on Android Studio coding here.

          A QR Code can contain an alphanumeric string that is processed by the App decoding it.

          You will probably need to use a library like https://github.com/zxing/zxing to decode the QR Code but once you have the content it’s up to the App what to do with it.

          You can probably define some kind of structure to store different URLs or redirect users to a landing page with the different URLs there.
