QR codes are common in marketing, especially online. These codes can contain links to other websites or simply provide necessary information to users.
In this blog article, we are going to take a look at how you can scan a QR code with your laptop camera and get the appropriate results!
What is a QR code?
QR code is a type of 2D barcode created by the Japanese company Denso. QR codes are often used in marketing and can be scanned with a smartphone camera to access information about the code.
Depending on the image being represented, certain patterns are used; for example, 17×17=64 possible checkerboard patterns give 1,104 different codes. The encoding of these patterns into the symbol allows it to be read by a camera or QR scanner with great accuracy.

The symbology for data in information systems usually consists of two layers: a matrix of square pixels and at least one character representing the symbol.
A representation of the QR code is obtained by reducing the pixel grid to a single square through sampling, usually with a Bayer filter.
The encoded information is located in the central square of the image (known as the “data element”). For example, if an image contains 128 data elements, then each pixel would represent two or three bytes of data, depending on how high-resolution the image is.
Types of Codes
QR codes are an efficient way to share information, and they’re becoming more popular each day. If you’re not familiar with QR codes, here’s a quick primer:
They’re two-dimensional barcodes that can be scanned using a smartphone or other device. When you scan a QR code, your device will typically display a link or image that you can click on.
Another type is a matrix or two-dimensional barcode. You can use QR codes to link two-dimensional barcodes together, which enables you to share information with multiple people at the same time.
QR Codes Are Everywhere. Whether you’re scanning a QR code posted on a billboard, checking the price of an item in a store, or boarding an airplane, chances are you’ll see one soon enough.
As you can imagine, this has led to an explosion in the number of QR codes appearing online.

First, open your favorite QR code scanning application. We recommend QR Code Reader, but there are many others available. Once you have the application open, input a valid QR code into the window and hit the “Scan” button.
You’ll see a green box around the code and a blue line going through it. The blue line is your cursor, so move it around the screen until the code is readable.
Once you’ve found it, hit the “Copy” button to save the code to your clipboard.
Now that you’ve saved the code, all you need to do is open up Windows Photo Viewer and paste it in. After pasting in the code, click on the “Open Image” button and then select “All Files”.

You can use an app like QR Journal which allows computers and Macs to recognize QR codes by using the front cameras. If you have a different device, you’ll be able to scan them with a webcam
In addition to QR codes, the application also supports direct scanning. The application is compatible with macOS but does not offer support for dark modes.
How to scan a QR code on Linux
Before going any further, we should note how to install the CoBang app on Linux. This not only includes installing the software but also indicates what remote desktop software is required to use it.
The first step when installing CoBanjg on Linux is to install it with a Flatpak package from the Flathub app store. However, you can also set up the app by installing one of three ways: by adding the repo to your Ubuntu software sources list, making use of the Arch Linux AUR, or adding it to your APT sources list.
Open up a terminal window on the desktop.
To install CoBang according to your installation preference, follow these installation instructions.
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
After Flatpak is installed on your computer, the next step is to add Flathub to the system. To add Flathub, execute a command in the terminal that enters this into the Flathub server.
flatpak install flathub vn.hoabinh.quan.CoBang
