Around 2014-15, I wanted to show that the web was an amazingly capable platform that was able to host experiences that were comparable to those of native platforms. An app that was touted as being impossible to do on the web was a QR code reader because it needed access to a camera and it needed to do it performantly and the only experiences on the web at the time were site that took the image via an <input type=file> element and uploaded it on the server.
