I have a $0.01 alternative to this randomizer app.... Flip a fair coin. Designate one side of the penny Heads, and the other side tails....
Also, even if they have 50,000 pre-check lanes, the total cost is still only $500.
But then TSA has to hire skilled workers. They have to be able to flip a coin.
