From EPIC.org:
Beginning in 2015, many federal facilities will require a “Real ID” for entry where identification is required. Several states have opted out of the Real ID Act, a federal mandate to modify the design of state drivers licenses, raising questions about the ability of people in those states to access federal buildings and board commercial aircraft. EPIC, supported by a broad coalition, opposed the Real ID regulations, arguing that many of the required identification techniques, such as facial recognition and RFID tags, compromise privacy and enable surveillance. EPIC, joined by technical experts and legal scholars, also provided detailed comments to the Department of Homeland Security about the program and later issued a L6[report: “REAL ID Implementation Review: Few Benefits, Staggering Costs” (May 2008).
