A new version of ticket gate that is capable of detecting explosives in three seconds is being given a two-day trial at JR Akihabara station, a representative from the Ministry of Education, Culture, Sports, Science and Technology said on Tuesday.
The new machine, developed by Hitachi Ltd, is similar in design to existing ticket gates but blows air from one side of the gate to the other, where gases collected are analyzed for traces of explosive materials. Materials used in the making of hand grenades and other explosives, such as those used in the 2005 London bombings, evaporate easily and adhere to clothes or skin.
A Hitachi employee said they hoped to collect data on 2,000 people by the end of Wednesday and were analyzing if the machine would make incorrect detections due to various kinds of cosmetics and body odors.
Hitachi's latest machine is said to be 99.9% accurate however, and the U.S government is rumored to have expressed interest, with a possible installation at airports or at public events in the future.© News reports
