AAI has placed orders for hitech inline baggage scanners. AAI has placed the work order with London based global Smiths Detection for hold-baggage scanners, which will be installed in nine airports across the country. The in-line baggage screening system means air travellers will no longer have to queue-up near the X-ray machines to scan their baggage before check-in and will also result in smooth passenger flow at these airports. The cost of such high tech baggage scanning system is around USD 50 million . The scanners will be installed at nine airports, including Chennai and Kolkata. The CTX 9,800 high-speed explosives detection system can scan 1,800 bags per hour and is certified by the US Transportation Security Administration and the Civil Aviation Administration of China.
