I figured that nobody would be stupid enough to transmit anything
"usable" over a phone line.

I don't doubt that some idiots tried to record the transaction, but I'm
sure it was of no use to them.

The Science Center at Liberty State Park in NJ has a transparent ATM,
made of 1" thick plexiglass. It actually works, and the last time I was
there it didn't even charge a fee.

Part of the "show kids how things in their world work" program, which I
think is great.
