You’ve got to give VeriChip credit for persistance, if nothing else. Utterly unfazed by people hacking and cloning their implantable RFID chips, and still cheerily touting them as a secure form of identification (when used in conjunction with other forms of ID, perhaps), their new target market is the subdermal tissues of the US Armed Forces. Their friends at the Pentagon seem fairly keen, but (as always where RFID is concerned) there’s a privacy backlash gathering pace.
