Manchester Airport in the UK has begun trialling advanced metal detector gates in a bid to automate screening procedures and end manual passenger screening.
The automated glass door, which will be trialled at terminal two, will replace the traditional archway metal detectors at the airport, according to the Manchester Evening News.
Passengers will walk through the gates and stand in the holding area. If anything suspicious is traced, the gates will signal an alarm and open a red door, and the passenger will have to pass through one of the new body scanners.
If nothing suspicious is traced, a green door will open within two seconds.
Once the trial is successful, the airport plans to install metal detectors in all three terminals, at a cost of £5m ($7m).
