It should reject the notes, irrespective of its true validity, in case any serious discrepancy on the note is sensed which do not commensurate with security feature of valid notes due to any external or internal reasons of whatsoever, it should get rejected at first instant, even if the note is found genuine latter on though re-verification by machine or any other methods.
