ABSTRACT:
A pair of tamper proof postage meter doors which remain closed and locked until the proper combination of numbers is entered using the normal postage keyboard. The doors will not function if there is insufficient postage in the accounting registers. Means are also provided which will cause the ascending and descending registers in the postage meter to indicate zero postage remaining in the meter if an attempt is made to tamper with or force open the doors.
