Abstract: Systems, methods, and other embodiments associated with terminal reading using an update list are described. In one embodiment, a method includes identifying request to modify an object having corresponding data stored on a smart card installed in a terminal; storing an object identifier for the object in an update list; modifying the data corresponding to the object per the instruction; and providing the update list for access by the terminal. In another embodiment, the method may also include receiving a card read command; accessing an update list; identifying one or more objects in the update list; and reading data corresponding to the one or more objects, such that data corresponding to objects in the set of objects that are not in the update list are not read.

Abstract: Techniques described herein include determining, maintaining, and applying compound service performance metrics, based on data metrics from a plurality of different services. Service-specific data metrics may be received from a plurality of different communication services offered by a service provider, for example, Internet service, voice service, video service, SMS service, etc. Different combinations, relationships, and weighting factors for the data metrics may be defined and stored for each compound performance metric. Compound performance metrics may be defined, including for example, compound customer sentiment metrics, compound customer value metrics, and/or compound customer resource usage metrics. In some cases, machine-learning and/or analytics may be performed using service-specific data metrics and corresponding customer actions, in order to determine correlations between particular combinations of data metrics and customer actions.
