Receiving is subjected to physical review, unless the machine is a RCDM. The machines are highly robust. Most of the mistakes are attributed to human error.

However, depending on which provider you choose, the error rate (though not published) is assumed to be somewhere between 1-in-100,000 to 1-in-250,000 dispenses. Mostly attributed to notes insertion into the cassette.
