QR Codes (2)

< Back to Education 02 course

 Goals:

    Please click the [ Mark Complete ] button at the bottom of this page when you’ve achieved the following goals:

  • Briefly explain the appearance of a QR code.
  • List at least 6 types of information that can be displayed by a QR code.
  • Explain the difference between a Static QR Code and a Dynamic QR Code, as we’ve defined them in our web sales pages. 
  • Be able to explain to a customer how they can use a QR code with URL auto redirect (a setup that enables you to change the QR code function by changing the function of the URL redirect to which the QR code permanently points)

This builds on QR Code information in Level 1.
If you haven’t completed this yet, see here: QR Codes introduction in Level 1…

Types of information that can be displayed via QR code:

  • Phone numbers
  • SMS or email message
  • V-Card contact details
  • Plain alphanumeric text
  • Videos
  • Web posts
  • Blogs
  • Websites
  • PDF documents
  • Business contact details
  • And much more… QR code functionality is still evolving.

Damage

QR codes can function even when damaged or positioned abnormally. QR Codes have their own data error correction data, internal orientation calibration and self-alignment markers. This enables them to be read upside down or wrapped around a curved surface.

Useful to know: Changing a QR code’s functional outcome by means of URL auto redirect

These are two common customer questions:

  • How can I edit a QR code so that it performs a different action?
  • How can I use a QR code to track website traffic?

The video link below takes you to a video showing how this can be done manually using a website URL auto redirect.
In this setup there is no need to edit the QR code.
It links permanently to a set URL, but the URL itself can be configured with an auto-redirect that you can easily change within one minute through your website’s back end.
If you set up Google Analytics on the auto-redirect URL you can also track visitors who use the QR code.

You can share this video with your customers by:

  • linking to it from your QR code information page
  • making a similar video yourself, or
  • writing a text explanation

   112 – Using QR code with URL redirect  
Coding a QR code to direct a customer to a web page is relatively simple, but what if you want to change the website URL after the QR codes are already out there in the world and you can’t recall them for re-coding? To resolve this, use “URL redirect”, where you code the initial Request URL on your website to redirect to a further Destination URL. This is a simple procedure that shouldn’t take longer than a minute, and it can be re-re-redirected at will in the future. Note that where Google Analytics is configured to track the Request URL, it will still register a hit on that page, but won’t provide detailed information such as time spent on the page – for these you will need to set up Google Analytics on the Destination URL | Refer to the video for the relatively simple procedure to redirect the URL |
With this solution you never need to change the initial QR Code |
