Claim:
1. A digitizer system comprising: an object incorporating an electronic circuit configured for radiating a first signal and a second signal in response to querying, the second signal separate from the first signal, wherein only the first signal is modulated with information for identifying the object; a digitizer sensor configured for detecting the second signal while the object is positioned on or over the digitizer sensor; and a reader other than the digitizer sensor operative to both query the object and detect the at least one modulated signal via air with an antenna that is separate from the digitizer sensor; circuitry configured for receiving input from the reader regarding the first signal detected and input from the digitizer sensor regarding location at which the second signal was detected, and for determining an identity code based on the input received by the reader, for determining a position on or over the digitizer based on the input received from the digitizer sensor, and for identifying the object and its position by associating the position detected with the identity determined.
