In a recent Time magazine
Revelation 13:16He also forced everyone, small and great, rich and poor, free and slave, to receive a mark on his right hand or on his forehead, 17so that no one could buy or sell unless he had the mark, which is the name of the beast or the number of his name.
So basically the idea is there is this mark, 666 which promotes the system of man over the system of God. We need to get the mark to continue functioning in the marketplace. Which obviously is the focus of this effort. The plan would be your fingerpring (hand) or retinal scan (forehead?) would serve as a bio identity marker so that we don't have any illegal immigrants sneaking in.
While I"m not saying this is the end or this is the actual mark I am saying this is scary, and this is something that we should be very wary of. Any effort like this should be roundly criticized, not only for it's cost, but also for it's stance that people need to buy into the nation state system in order to be treated like human beings. This is one area that I widely disagree with the republican party and America in general. I like free trade and outsourcing. I think opportunity for those in countries with less wealth and opportunity than America is a good thing. I think spreading the wealth around via the extended free market makes a lot more sense than protectionism for America's poor when the foreign poor are willing to work a lot harder.
