QR Code stands for Quick Response Code. They look like a pixelated barcode in a square shape with tiny square pixels in random parts, creating a unique pattern. These patterns are considered alphanumeric or even numeric and, at the same time, binary. You can scan these codes using your phone or a barcode scanner which directs you to a specific URL or text or any other information. The unique QR code system came into existence in 1994 by Masahiro Hara from the Japanese company Denso Wave.

However, today, QR codes are even used broader and more comprehensively for both commercial tracking processes and the convenience-oriented applications available. As a result, the practical uses of QR codes are vast, especially

Just like a barcode, information is translated into binary form (ones and zeros) and stored in the patterns on a QR Code. The size and alignment of the black and white squares on a QR code are encoded texts or URLs that are immediately translated into English upon scanning by an optical sensor (AKA your phone’s camera).

By QR code generator, we simply mean the software that merely stores the data into a particular QR code, such as documents, files, links, or even an address belonging to a website.

Building a QR code can be done quickly with the help of our online QR code generator ddqr.me. All you need to do is simply create a QR code by just typing the data and designing it based on your desired shape or format and then download the image in a high-resolution PNG or even vector graphic.

Now you are able to print the final free QR code or even embed it on the website with our QR codes and make sure it is available to all.

QR codes are conventionally divided into static and dynamic. The difference between these types is in the way they store information which we will explain below.

Static QR Code

Static QR Codes are basically fixed, meaning they cannot be changed or modified in any way. By scanning a static QR code, you are led to a URL that should never change or be modified. A static QR Code might be useful as a restaurant menu or on anything left untouched for long periods of time, but using it on products or adverts could lead to many issues and complications. The URL for products, adverts, or pharmaceuticals constantly changes due to updates or new versions. If a URL is modified and you use a static QR code on the product, the new URL would render the old QR code useless. Therefore, to fix this problem, dynamic QR codes were introduced.

Dynamic QR Code

Dynamic QR Codes are visually no different from static ones, but scanning a dynamic QR code sends the users to a short URL that later re-directs them to the final destination site URL provided. The short URL simply works just like the intermediary that can easily connect the QR code along with data for the users. The data even can be designed as a landing page for selected resources such as weblinks, Social media links, Videos, Youtube links, Audio files, and any type of files (e.g. .docx, .pptx, .pdf, ..).

Once the QR code is generated, you will be able to edit or change the URL or all the resources behind the QR codes. There is a reason why dynamic QR codes are better than static QR codes. For example, suppose an individual constantly changes their mind regarding how they desire to use their website URL or they would like to share different files and links. They also wish to use their URL on different websites and social media like Meta (Facebook) or Instagram. With a Static QR Code, the individual must generate a new QR code every time they change their URL or resources, and doing that can be time-consuming and even impossible at times. With a Dynamic QR code, though, all the URL and file modifications would be possible, and the generated QR code wouldn’t need to be regenerated and changed.
