RFID is now booming and lots of application started to use RFID. After two and half year of development at the University College London, a new technology to tag passengers in the airport will be trialled in Debrecen Airport in Hungary. People will be told to wear radio tags round their necks when they get to the airport. The tag would notify a computer system of their identity and whereabouts. The system would then track their activities in the airport using a network of high definition cameras. If this project is successfull, then it can be deployed in other places as well in the next two years.
