Abstract
An electronic postage meter system in which a postage meter is coupled to a data center by way of a communication path, to enable recharging of the accounting register of the postage meter under the control of the data center. The postage meter includes an arrangement for applying dialing signals to the communication path for initiating a request for recharging of the postage meter register, and for interrupting the communication prior to the receipt of recharging authorization. The data center is responsive to a request for recharging the postage meter register to apply dialing signals corresponding to the expected location of the postage meter to the communication path to re-establish communication for the transmission of recharging authorization signals. The interruption and subsequent re-establishment of communication verifies the continued location of the postage meter at the expected location.
