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. 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.
