Super-clone sniffer dogs, and Bluetooth passenger tracking are being trialled

CNN  — 

After the EU’s announcement that it will ban “backscatter” x-ray body scanners, airports may have to look harder at alternative security measures. From Bluetooth tracking to thermal lie-detector cameras, we take a glimpse into the weird and wonderful future of airport security.

The check-point of the future

Earlier this year, the International Air Transport Association (IATA) demonstrated its vision for the “checkpoint of the future” – a series of neon-lit tunnels, each equipped with an array of eye-scanners, x-ray machines, and metal and liquid detectors.

Heralding an end to “one size fits all screening,” the association says that passengers will be assigned a “travel profile” and ushered into one of three corridors accordingly.

“Known Travelers,” (those who have completed background checks with government authorities) for instance, will cruise through the light blue security corridor with little more than an ID check, while those guided through the yellow “Enhanced” corridor will be subjected to an array of iris scans and sensitive contraband detectors.

Although still at the proof of concept stage, the IATA is hoping to have these colorful checkpoints installed in airports within the next five to seven years.
