I'd just plan on changing the PIN afterward. I think between hackerspace members and coworkers, I could easily come up with 63 trusted test partners. I'd of course do some good tracking to make sure I got all the cards back (maybe escrow one of theirs in place of mine), although that could get tricky if any ATMs got pissed off enough to start swallowing them. I guess everyone also has to record video of their attempt? It'd be fun to coordinate, for sure. I wonder how wide a radius you'd need to cast to get 64 working ATMs....
