OSI Systems Inc. (OSIS)’s Rapiscan unit, one of two suppliers of passenger-scanning machines in U.S. airports, may have falsified tests of software intended to stop the machines from recording graphic images of travelers, a U.S. lawmaker said.

The company “may have attempted to defraud the government by knowingly manipulating an operational test,” Representative Mike Rogers, chairman of the House Transportation Security Subcommittee, said in a letter to Transportation Security Administration chief John Pistole Nov. 13. Rogers said his committee received a tip about the faked tests.
