ATM code (3)

I believe the answer is:

'atm code' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for pin that I've seen before include "Badge" , "Secure" , "Stick with flag placed in golf hole" , "form of identification" , "Small object to fasten or attach" .)

I've seen this clue in the LA Times, the USA Today and the Universal.
