PSID is based on "potential". All you would need is one globally agreed-upon reason for having a microchip injected subcutaneously and PSID could very well go off like a rocket. They are way ahead of the game in this regard.
Unfortunately there is no real need (right now) to have a chip like PSID's injected into yourself.
However, if the antichrist just happens to appear in 2010 ...then you can bet your bottom dollar he'd be mandating a sub-Q self-identifying microchip being injected into the world's population!
