the QR image can be loaded into browser context via MediaCapture API, data-uri string(https://en.wikipedia.org/wiki/Data_URI_scheme) or remote image. reading qr code has no dependency to camera. to display qr code at browser, I found a proposal from ETRI. http://hollobit.github.io/qr-element/ to generate URl from qr code, missing currently. If Kepeng Li has interest, we can talk more for this.
