1. A sensor network system comprising:
- a plurality of sensors at known locations, each sensor having a microcell and capable of communicating wirelessly with a personal digital key (PDK) in its microcell and gathering position data about such PDK, the PDK containing a memory having service blocks, each service block accessible by a corresponding service block access key;
a sensor management module (SMM) communicatively coupled to the plurality of sensors and configured to facilitate communication with one or more applications;
wherein the SMM and the sensor provide a data path between a service block on the PDK and an application that has access to the corresponding service block access key; and
the SMM receives the position data gathered by the sensors about a PDK, generates location tracking data for the PDK based on the position data and makes the location tracking data available to applications.

Abstract
A personal digital key (e.g., which can be carried by a human) contains a memory having different service blocks. Each service block is accessible by a corresponding service block access key. As the personal digital key (PDK) moves around, it is detected by sensors. The sensors report position data, thus enabling location tracking of the PDK. The sensors also provide a data path to various applications. An application that has access to a service block access key can therefore access the corresponding service block on the PDK. The sensors themselves may also contain service block access keys.
