Funny story: In a previous job I led a team developing the UK Post Office's self-service kiosks. Because of that work, another national post office in Asia contacted my company to investigate a similar kiosk. One of their requests -- I swear this is real -- was a "snake detector." Apparently, mailing snakes out of the country to be sold as pets is a real problem. We never quite sorted out the best way to accomplish that.
