thats why it has to be something that scans your dna from a living body and not just dna samples

or it can just scan your eyes, or Sony created a system that cheaply and easily lights up your earm with super bright LEDs and scans youre VEINS which are unique (except i know people who use IV drugs whose veins change and shift all the time lol ) so maybe that wont work as good as an Iris scan ...Most smartphone cameras are more than capable of perfect Iris scanthey are all just missing a macro lens...which i just ordered for like $3 with shipping ...and that will let u scan your own retina with a smartphone, that will be what we ned, unless someone can create a fully 3d version fo smeone in CGI which would require the millions fo dollars in Ethereum or golem to render out in Live real time 9but with ethereum or ggolem it could be done or the future instanious blockchain stuff that will allow you to rener games in real time on yoru smartphone and pay for it with ethereum!
