VOXX also has/has invested largely in a USB retina verifying password device called Eyelock Myris retina I believe. Which is almost as secure as DNA and is way safer than the IPhone (or something) touch password or something (all detailed in the following video) which still caused possibly celebrity photo hacks etc and besides is just much less secure than retina scan. Apple I believe bought the touch secure technology for a few hundred million a few years ago, so they'll/someone probably pay way more for this retina scan.
