Metering system with automatic resettable time lockout |
摘要 |
A postage metering system is provided with a countdown time. The countdown timer issues a priority interrupt when the timer has timed out which interrupts the control system of the meter in such a manner as to hold the meter in reset preventing operation of the postage meter. The timer is reset to a fixed period upon each funds recharge after the meter has been placed in recharge mode but prior to exposure of the secure accounting memory to recharge information.
