Leading research group Frost & Sullivan have predicted that the passenger experience will be transformed in coming years as automation and pre-processing reduce physical interactions with travellers.As a result, the global spending on passenger screening technologies, which stood at $1.42 billion in 2014, expects to reach $1.63 billion in 2020, say F&S.The group's new analysis on the Global Airport Passenger Screening Market finds that an assortment of portal scanners, biometric collection devices, and pre-clearance based on voluntary background investigations will take over the screening process."To deal with the escalating passenger traffic, airports need to implement swifter and more efficient methods of passenger screening," said Frost & Sullivan Aerospace & Defense Senior Industry Analyst John Hernandez. "One solution could be to supply passengers with alternate venues and automated tools to prescreen them before they arrive at the airport."Identifying high-risk passengers is only one element of establishing a more efficient airport passenger screening operation. For a more thorough system, airports are looking for innovative technologies capable of screening a large number of people quickly and accurately. Additionally, deploying scanners than can detect nonmetallic improvised explosive devices will also be imperative."Airports already employ automated systems such as automated passport control kiosks and automated border control, eGates, for international travel," observed Hernandez. "The next step is to transition automated passenger screening to airport checkpoints. Equipment maintenance and recurring training will be critical selling points to agencies responsible for procurement."
