A new generation of x-ray machines can possibly ease all security limits on cabin luggage. As airports continue to beef up and overhaul their security regimens, hi-tech equipments are usual additions to this end.
The X-ray machine would speed up the process of passing through security gates as scanners take four images of every luggage item from different angles. It also has sensors to sniff out explosives. The new screening system is still being tested and there are no guarantees yet that its use could actually lift luggage restrictions. As of the moment, the search continues for a more viable alternative to the one-bag system.
