RFID in our wallets

The Virginia legislature heard testimony today about the wisdom of implanting RFID chips in their state driver's licenses.  No state currently uses RFID chips in driver's licenses, but once past that obvious target, resistance to the technology would likely diminish significantly.  Because the RFID tags would essentially broadcast personal information to anyone nearby with a reader, the ACLU is actively involved in dissuading Virginia from this plan.  But given the strong RFID push from the Bush administration, immediate testing of RFID tags in a limited fashion, such as in one state's driver's licenses, could provide much-needed empirical evidence of privacy infringement.  Such a scenario could stave off more aggressive RFID plans such as a federal mandate for RFID-enabled driver's licenses nationwide, RFID-enabled passports, or other types of ID cards such as those envisioned for federal employees.  Just as long as the pilot test is not in my state.
