Yes, I once ended up reading a book on Automatic Teller Machines when I
really wanted a book on Asynchronous Transfer Mode (it was an
interlibrary loan, I do riffle the pages when I have the book in hand),
but it was interesting anyway. There are mechanisms in the ATMs to guard
against all sorts of situations, such as double counting to detect stuck
bills, etc etc. I'm sure there is a small chance of an undetected error
but the humans surrounding the system are more likely to give you grief.
Another interesting fact in that book was how NCR captured the bulk of
the market.
