>> reporter: hi, brian. this new procedure comes after the attempted bombing of that delta northwest flight 253 from amsterdam to detroit on christmas day. the tsa says these screenings will be random. pulling passengers aside and swabbing their hands with a cotton material, then putting that swab through a director looking for any traces of explosive residue. the tsa already does this on hand luggage pull add side for secondary screenings. now, this technique will be used on the hands themselves. the tsa recently tested the technique over a two-week period at five different airports, atlanta, orlando, raleigh, as well as pitt greenville, north carolina , and coastal carolina regional airport in north carolina , as well. it takes just a few seconds. usually happens in and around tsa check points, and perhaps even the gate. there have been other security enhancements since december. more dog teams, more federal air marshals , more behavioral profiling seen and unseen, all designed to make it hard for terrorists to predict when and where they might be spotted.
