RFID plane tickets to track travellers

RFID plane tickets to track travellers:

"Scientists at University College London (UCL) are developing a system that combines radio frequency identification (RFID) tags and high-definition CCTV cameras to track passenger movements in busy airports.

The EU-funded project, known as Optag, is intended to help airlines keep track of passengers and help them reach departure gates on time, reducing the risk of missing valuable take-off slots."
