Abstract
A postage evidencing system including a plurality of domains for partitioning a population of postage meters according to an operating characteristic, a data center, a postage meter in operative communication with the data center and a printer in operative communication with the postage meter. The postage meter is initialized to operate in a particular domain while the printer is capable of operating in each of the plurality of domains. To update or enable a domain in the printer, the postage meter transmits an indication of the particular domain to the data center. Then, the data center encrypts the indication and transmits the indication to the postage meter which in turn forwards the encrypted indication to the printer. The printer decrypts the encrypted indication and using the indication enables a respective domain in the printer corresponding to the particular domain of the postage meter. A method for updating domains in a postage evidencing system is also provided.
