The TSA is constantly trying to improve security, and one of its recent such endeavors was the introduction of a randomizer app. Meant to implement a non-discriminatory process and make it harder for terrorists to detect patterns, it's employed by officers at 100 airports, who hold an iPad and use the technology to direct people to different lines.

While the app has been in use for a few years, no one knew its cost. That was until developer Kevin Burke did some digging and submitted a Freedom of Information Act request in December 2014 to get the info. He finally got a reply this month.

The response explained that IBM received the development contract, which cost $336,414.59 in time and materials. It was also revealed that other components of the deal added up to $1.4 million, but it was unclear exactly what that included because parts of the document were redacted.
