According to the government, all major British airports will need to introduce 3D baggage tracking equipment by the end of 2022.
The ministers say the technology will increase safety, accelerate pre-boarding controls and end fluid and laptop travel restrictions.
The equipment, similar to the CT scanners used in hospitals, is already being installed in London's airport heathrow.
It provides a clearer picture of the contents of a bag that employees can zoom in and out for review.

"By facilitating travel through British airports, this new equipment will help strengthen the crucial role of our airports in securing Britain's position as a global hub for trade, tourism and investment," he added.
Heathrow announced it will spend £ 50m on technology in the coming years.
It is the first British airport to install the equipment that has since been tested in 2017.
The airport's managing director, John Holland-Kaye, said it would "less disturbing" travel, adding that the scanners could detect which fluid is in the luggage.
The scanners are due to be rolled out to other British airports in the next few years.
Transport Minister Grant Shapps said the new equipment meant "there are no more socks and underwear to take off and you need to separate your fluids and take out your laptops."
Changes, rather than the taxpayer.
The technology is already in use by US airports, including Hartsfield-Jackson of Atlanta and O & #; Hare of Chicago.
