1. An apparatus for tracking the length of time spent on each of a plurality of different tasks on behalf of a plurality of different entities, the apparatus comprising: a plurality of tokens, each including a remotely readable electronic tag coded with predetermined information uniquely associated with at least one of (i) a task, and (ii) an entity; and a sensing device including a sensor for detecting the electronic tag of a token when the token is at a predetermined position relative to the sensing device, timing circuitry for generating a start signal when the sensor first detects the electronic tag and a stop signal when the sensor ceases detecting the electronic tag, and decoding circuitry for generating a data signal with content based on the predetermined information identified by the detected electronic tag.
