Radio frequency identification (RFID) is used at McCarran Airport, where the IT department is deploying RFID baggage tags on a wide scale. Because almost all its flight information, baggage handling, and check-in systems are common use equipment, the airport is well suited to test RFID. The IT department is able to coordinate an RFID tag project over the whole facility, while in many other U.S. airports, airlines choose and manage their own IT. In April 2004, McCarran will start attaching stick-on RFID tags to bags. It will move explosive-detection system from the terminal floor to a separate bag-screening area. By December 2004, the RFID chips will be embedded in bag tags. Chips and readers are supplied by Matrics. The alternative to RFID was optical scanning with barcodes, which requires more labor because barcodes often have to be scanned manually. RFID tags are more accurate than barcodes as well, since optical scanners' accuracy rate is usually about 87 percent, while RFID accuracy is 99.7 percent. McCarran and Matrics say their price figures are accurate (25 cents each for tags), although some other experts are skeptical, and they say they are sure that RFID prices will decrease substantially. The progress of the project is described, including the completion of Phase 1 of CUSS (Common Use Self-Service) kiosks, which allow travelers to check into flights and issue boarding passes for any airline at the airport.
