According to an article by Government Computing News, opponents to the use of the technology, including Citizens Against Government Waste and the American Civil Liberties Union, are protesting against the high cost of RFID, its lack of standard technology, and the potential for unauthorized remote readers to access personal information contained within the chips.

While the Homeland Security Department (DHS) is shortly expected to release guidelines on which machine-readable technologies must be used to meet Real ID Act standards, the groups will continue to seek further backing for their cases against the use of RFID.
