Dynamic vs static QR code: what are the differences ?
We all know what QR codes are. But still, the differences between static and dynamic QR codes are quite confusing. We will see what makes them different.

What is a QR code ?
Let's start with the basics. According to Wikipedia, a QR (quick response code) code is "a type of matrix barcode (or two-dimensional barcode) invented in 1994 by Japanese company Denso Wave." that "contain data for a locator, identifier, or tracker that points to a website or application." and "consists of black squares arranged in a square grid on a white background, including some fiducial markers, which can be read by an imaging device such as a camera"
Didn't get it and I'm sure it's the same for a lot of you. So let's give a simpler non-technical definition.
A QR code is a two-dimensional barcode that can be scanned using a smartphone or other mobile device to quickly and easily access information or a website. It consists of black and white squares arranged in a specific pattern and can contain a variety of information, such as URLs, text, and contact information.
This is what we also call a static QR code.
What is a dynamic QR code ?
A dynamic QR code works the exact same way as a static QR code: it stores data in black and white squares arranged in a specific pattern. But the difference lies in the data it stores. Let me explain.
A dynamic QR code stores the link to an URL that instantly redirects the user to another URL, the one that your user will land to. The process is the following:
- You scan the dynamic QR code
- You land on the first URL
- You automatically get redirected to the final URL
You may be asking yourself what's the point of having an additional URL. Well, this is what makes it dynamic; meaning that the QR code can be edited at any time. In other words, you can update the link of your QR code without re-printing a new one.
What's better: static or dynamic QR codes ?
The answer is very simple: dynamic QR codes are better than static ones. They offer much more flexibility and advantages:
- Flexibility - you can update the data of your QR code at any time
- Tracking - with dynamic QR codes you can (depending on your implementation) see how many times and where your QR code have been scanned
- Less expensive - if you plan to use your QR codes on communication supports like flyers, you won't need to re-print them just to change the QR code data
