First, capture the photo of a QR code, and transfer it to your computer, or save the QR code on your computer, if you come across it while surfing on the web.
So if you are on Linux, I will recommend you to use the web to decode or process QR codes, and that is the most convenient way, I would say.ġ. Moreover, unlike ShareX, there aren’t many options available to scan or decode QR code directly from the screen. On Linux and the webĭecoding or processing QR codes on Linux isn’t that straightforward, and it is all about using the terminal, which most don’t find convenient. I will not recommend you to decode or process every single QR code that you come across with ShareX, as most of them are supposed to be decoded or processed by smartphones, using Google Lens, to save contacts, visit a website, or some specific apps like PhonePe, Paytm, for making payments, etc. Unlike scanning QR code with a mobile, decoding or processing QR codes with ShareX will not help you accomplish tasks automatically. Whichever decoding method you follow, the decoded information will be displayed to you in text format, as shown here.ħ. Alternatively, if you go for decoding from the screen, just select the file on your local storage.Ħ. If you choose to decode from the screen, you will get an option to crop or select the area of the screen where the QR code is present. Now depending upon whether the QR code is saved as an image file or it is on the screen, click on the appropriate button.ĥ. So without any further delay, let’s get started with how you can process QR codes on a computer.Ĥ. So what you just need is the soft copy of a QR code in an image format, whether fresh or captured by a camera. Just imagine, how weird it will look, if you point your laptop’s webcam to a QR code that you can find on the streets. As the webcams on computers and laptops aren’t mighty enough, it will not only be a bad idea to scan the QR code using that low-resolution camera, but it will not even be convenient to do that. With the ability to process QR codes on a computer, you can visit webpages, see a contact, and do almost everything that is possible with scanning a QR code with a mobile, if the operation isn’t restricted by the OEM or on the platform itself.
QR CODE READER WEBCAM WINDOWS
While QR codes are supposed to be scanned with mobile devices to carry out tasks on the go, it is even possible to process QR codes on a Windows or Linux computer. This is error-free as the work is accomplished by the phone’s camera, which can hardly do anything wrong in scanning the position of some black and white dots on a square. There is nothing better than QR codes to bookmark or open a new web address, save a contact, make payments to a vendor, copy some text information, connect to a Wi-Fi network or do anything else of that sort, error-freely.
