RFID in the aviation industryRFID uses radio-frequency electromagnetic fields to transfer data that uniquely identifies each bag. In addition, RFID does not require line of sight to the bag, and so can identify many bags at once.

The RFID chip is incorporated in a permanent bag tag, which can be used multiple times. The passenger owns the tag and the airline updates it with new travel information each time they fly. The multiple use baggage tags are used for tracking and give data for operational optimization.
Radio Frequency Identification (RFID) for baggage tracking provides the data that allows airlines to efficiently track the bag through all airport processes. With IATA's Resolution 753 now in effect, airlines have started to implement baggage tracking.
“Millimeter wave imaging technology does not detect items inside a passenger's body or penetrate the skin,” Langston says. That said, Malvini Redden says body scanners would also not pick up anything else stashed inside a body cavity, such as drugs or hazardous liquids.
A good X-ray scanner will always detect money. Airport scanners can detect even the smallest amount of metal and can detect paper. The scanners will always look after things that look different to the norm. In this case, if the currency is arranged in bundles, it will be more easily detected.
The conveyor belt carries each piece of baggage through the X-ray beam, and on the opposite side of the tunnel, a detector measures the amount of radiation which has penetrated the scanned item. Dense substances, such as lead, absorb the most radiation, blocking the X-rays' progression”, explains Mikko Halonen.
