Tampa International Airport in the US has introduced technology to swab the hands of random passengers in an effort to detect explosives.
The Transportation Security Administration's (TSA) swab security officials will randomly swab the palms of passengers to trace explosives using portable explosive-trace detection technology as part of its airport security measures.
The officials will use portable equipment that will allow them to go anywhere in the airport to test people for explosives, according to cfnews13.
The officials will swab the hands of passengers waiting to get into the security checkpoint or those waiting for a plane. Officials believe the random tests will not cause any delays as they are carried out while passengers are already queuing.
If the swab test turns out to be positive, the passenger will have to undergo further screening.
To avoid mix-ups, TSA officials will dispose of the swabs after each use.
