Abstract
A method and system for providing external user interfaces is described. In one configuration a co-located external processor and a business machine negotiate a communications connection. The co-located external processor then utilizes a server to determine a shared secret in order to pair a wireless connection with the business machine in order to act as the user interface for the business machine. In another configuration, the co-located external processor is connected to a remote data center that authenticates the user and provides the user interface code and secret pairing information to the co-located external processor. In another configuration, the co-located external processor performs data processing for providing a cryptographically processed print stream to a postage meter.
