Seriously, this is what they spend our tax dollars on! It would be better if they used a cardboard sign and turned it each direction.
If you have traveled lately you probably saw a TSA agent holding a tablet that pops up an arrow that tells you which line you should stand in. That app is called a “Randomizer” and TSA agents use it to determine who is subject to the random searches that are a part of the TSA Pre-check program.
It appears that arrows do not come cheap, the Transportation Security Administration (TSA) paid IBM $47,400 for the app, part of a larger $336,000 payout to IBM.
