Communication devices. Seriously. Spy trick to communicate internationally without detection:
Open an account, give two guys cards and set up a code system ($20 w/drawl means Plan B, $100 deposit is Plan C)
One guy in, say London, w/draws a set amount (say $20)
The other guy can instantly see the money has been taken out and knows what it means

Off topic a little, but thought it was cool
