The tattoos, developed by Massachusetts-based engineering firm MC10, contain flexible electronic circuits that are attached to the wearer's skin using a rubber stamp. They are made from silicon and contain electronic circuits that bend and move with the wearer's body. The tattoos, called Biostamps, were designed for medical purposes to track a patient's health, but Motorola thinks the technology can be used for authentication purposes, as an alternative to traditional passwords and mean you can use them to buy stuff with.
This is exactly what US Born Again Christians claim will be the mark of the beast and was the central theme to the Christian horror flick “Thief in the Night”. To quote Revelation 13:16-18:
“Also it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name.”
Of course the Bible fails to mention that you can wait for up to a year to get an Adsense account from the beast, but we expect that was in the sequel, which we never got. The first prototypes were stuck on using an plaster-style patches. More recent prototypes are applied directly to the skin using a rubber stamp.
It can then be covered with spray-on bandage to make it more durable and waterproof enough to wash. The MC10 Biostamp is said to last up to two weeks before it starts to come loose, but by then the devil will have caught hold of your soul and a voice will cry out “shoot.” (An appropriate Genesis reference).
Of course other than the thing falling off every two weeks it sounds like a good idea to us. But then again I sacrifice black goats to Chthonic gods every weekend to bring to an end Steve Jobs and all his works.
