There is a thread about the patented KYC method.....(link below).... from memory whilst it does exist as an approved patent (to iSignthis Ltd from memory but in what jurisdictions?? not sure if US approved yet but pretty sure EU has been). nobody in that thread discussion could identify a real life website that used it (so it could tried out by shareholders in the real world). Unsure if any have been identified since.
From memory there are simulated uses on youtube .... but only a simulation that I could ever find.
