A couple of years ago, QR-bills were introduced in Switzerland as a means to make payments easier. My bank provides an app to scan the QR codes, which I prefer not to install. The only other option they provide to scan the codes is to use the webcam. Am I supposed to print my digital bills to have my webcam scan them again? Just let me upload a goddamn screenshot.
You could use OBS to setup a virtual webcam, which would then show your receipts.
