Additionally, he punches alphanumeric keys in a prescribed manner into keypunch 6 so as to further identify the user, this precaution being taken should one attempt to use the card in an unauthorized manner. The keys of the keypunch return to the cleared condition immediately after punching the code, so that a subsequent user or onlooker cannot observe the punch-key code. When the keypunch and cardreader ascertain an authorized user, it sends out a signal along output line 8 to start copying. Once copying begins, the copier super-imposes, in an appropriate free space of the copy, the user's identifying number, the date and time of use, and the particular copier (its identifying number and/or letter) from which the copies were made. The copier is also equipped to number each copy in sequence when more than one copy is made.
