Others worry about a day when hackers might deploy readers at “chokepoints,” such as checkout lines, skim RFID numbers from people’s driver’s licenses, then pair those numbers to personal data skimmed from chipped credit cards (though credit cards are harder to skim). They imagine stalkers skimming RFID tags to track their targets and fear government agents compiling chip numbers at peace rallies, mosques or gun shows, simply by strolling through a crowd with a reader.
Others worry more about the linking of chips with other identification methods, including biometric technologies, such as facial recognition.
Should biometrics be coupled with RFID, “governments will have, for the first time in history, the means to identify, monitor and track citizens anywhere in the world in real time,” said Mark Lerner, spokesman for the Constitutional Alliance, a network of nonprofit groups, lawmakers and citizens opposed to remotely readable identity and travel documents.
The International Civil Aviation Organization, the UN agency that sets global standards for passports, has called for facial recognition in all e-passports.
