The tester included a note in the lab's report praising the system for having the best voting software he had ever seen, particularly the security and use of encryption.
Doug Jones, Iowa's chief examiner of voting equipment and a computer scientist at the University of Iowa, was struck by this note. Usually testers are careful to be impartial.
But Jones was not impressed with the system. Instead, he found poor design that used an outdated encryption scheme proven to be insecure. He later wrote that such a primitive system "should never have come to market."
