QR code, short for Quick Response Code, is a kind of matrix barcode that includes information about a product or service. You can find it being used for advertising purposes, where brands put up custom QR codes on their products to market them. As a matter of fact, these days, QR codes are not only being used by the advertising industry but by other industries and individuals as well.
One of the significant reasons behind such widespread adoption of QR codes nowadays has to do with the kind of convenience they facilitate. In fact, this convenience, coupled with quick access, is what enables users to fit more information into a tiny screen/canvas. So the obvious question that pops-up then is what exactly is a QR code, and how can you generate a QR code yourself? Here’s a guide with answers to these and a few other related queries.
What is a QR code?
A QR (Quick Response) code is a kind of matrix code that possesses the ability to hold information about a product or service. It consists of three square structures in its corners and can include up to 2953 binary characters.
Talking about its structure, a QR code features a combination of black cells arranged in a square grid on a white background. This layout is in stark contrast to matrix codes that are made of black and white cells and do not have designated square structures in the corners, and barcodes, which are one-dimensional and can hold limited characters.
In general, QR codes can be classified into two categories: static and dynamic. Static QR codes are those that can contain a fixed set of information and cannot be changed once created. On the other hand, dynamic QR codes possess the ability to be edited at any time, even after their creation. These codes also provide the option to track data like total scans, location of scans, average scans per day, device type, and a lot more.
When stacked against each other, dynamic QR codes come out on top as a more preferred choice for most businesses and individuals. This is because they can be tracked, edited, and customized to meet one’s requirements, unlike their static counterparts.
Some of the common applications of QR codes include serving download links for apps, giving navigation guides for destinations, collecting customer reviews, taking polls, capturing contact details using a landing page, sharing business cards, and more — the use-cases are endless.
How do QR codes work?
Generally speaking, a QR code involves two steps: creation (or generation) and reading, to work. First, the creator needs to generate a QR code with the information they intend to convey through it and attach it to the relevant product or service. After this, the reader, who wants to read information from the QR code, is required to use a QR code reader to retrieve information from the QR code. A QR code reader is available as a built-in utility on some smartphones. In case it isn’t, on your device, you can download a third-party QR code reader app from your smartphone’s app store.
In a nutshell, a QR code works pretty much similar to a traditional barcode, where the creator encodes some information into a code and the reader reads it using their smartphone to obtain the information in a human-readable format.
How to generate a QR code?
Depending on what kind of QR code — static or dynamic — you want to create, there are different tools (apps and services) to help you achieve the same. But at large, there are two approaches to generating a QR code: using an app/service or using code.
Since most users would want a quick and easy way to generate a QR code, the former approach should work just fine for an ideal use case. However, if you want more control over what information goes in your QR code and need more customizability, you can code your own QR code. For the purpose of this article, we will stick to third-party apps and services to generate QR codes. But if you wish to create your own, you can check out this tutorial to generate a QR code with Python.

Visualead is one of the popular QR code generation solutions out there. It is available as a web app and is pretty easy to use.

The action can either be a destination URL or a landing page. Once that’s done, you can then choose a template design or upload your own image to generate the design. If you are creating dynamic QR codes, Visualead provides you the ability to edit them and make changes at a later time. Your QR should now be ready. And you can choose to either print it or share it.

Talking about usability, QRStuff has a very basic set of steps that you need to follow to create a QR code.
