Radio Frequency Identification technology (RFID) has been used successfully along our land borders with Canada and Mexico since 1995 in the Department of Homeland Security's trusted traveler programs, such as NEXUS, SENTRI and FAST. U.S. border officials are able to expedite legitimate cross-border travel and trade of those trusted travelers who carry membership cards with vicinity read RFID chips that link to government databases. Membership in these programs currently exceeds 400,000.
RFID technology has been commercially available in one form or another since the 1970s. It can be found in car keys, highway toll tags, bank cards and security access cards. The Department of Homeland Security's Customs and Border Protection (CBP) officers, who staff the ports of entry, anticipate that the speed of vicinity RFID will allow CBP officers, in advance of the traveler's arrival at the inspection booth, to quickly access information on the traveler from secure government databases, and allow for automated terrorist watch list checks without impeding traffic flow. In addition, they foresee that multiple cards can be read at a distance and simultaneously, allowing an entire car of people to be processed at once.
The RFID technology embedded in documents will not include any personally identifying information; only a unique number that can be associated with a record stored in a secure government database will be transmitted.
