Der Parson's rant

Some interesting stuff, found this article about Spy Coins. A google search gives some good articles about them and if they would really be that useful. If you give someone one of these tracking coins, how do you keep them from spending it? This just seems to have good potential to be a spy comedy movie. A bit like "The Man With One Red Shoe". Ah the wackyness that would ensue when a spy agency uses a tracking coin to keep tabs on a enemy agent, but unknown to the trackers, the coin has been used to buy a double latte. The agents spend hours outside a coffee shop until the poor innocent coin is given to some unsupsecting suburan delivery truck driver as change. I'm thinking this could be a blockbuster. I'm thinking Spielberg, Tom Hanks, and Angelina Jolie. This could be huge. I just need to learn how to write a screenplay, and off to Hollywood.
