Newark Liberty International Airport in the US will be installing state-of-art X-ray machines over the next two weeks to improve bag screening.

The new machines, which use 3D technology, are expected to improve safety and reduce the queuing time for passengers passing through the gates.

The modern X-ray machines enable the officials to check the baggage without opening sealed bags or luggage.

Around 40% of the airport’s boarding gates use the technology already. The machines are in use in terminal A and are currently being installed in terminal C.

The machines cost around $100,000 each.
