If Americans aren't stupid enough to get ID chips implanted in them, go south of the border! The most brilliant thing here is that it turns out they aren't putting any actual DATA on the chip itself. Its JUST a serial number. You have to cross reference it with a database, which would presumably be easy to get access to as they want readers all over the place. Hack the database, switch the records, and your vitcim disappears.
