The inventors of a new monitoring system that uses RFID tags claim it could improve airport security by tracking passengers as they mingle in the departure lounge.

The plan is to issue an RFID (radio frequency identification) tag to every passenger at check-in so human traffic can be monitored throughout the airport via transponders and video cameras.

Paul Brennan, an electrical engineer at University College London, heads the project, which features an RFID technology called Optag. Funded by the European Union, the technology is being developed by a consortium of European companies and the university. Brennan told Silicon.com that a prototype RFID tag will be tested in an airport in Hungary next month.
