QR code addition

Imagine you want to send a file from your computer to a colleague’s messaging app (Viber, Whats App, etc…)
You would have to upload file to Send, get link, send link to your smartphone and then forward it to a colleague.
But, is it possible to add QR code to Send site, which will generate only to person who uploaded file, so that person is able to open and forward link right away by smartphone, after scanning QR code?
