For a device that small, I would think that power would be applied, and signals received, via an external RF antenna & source, in much the same way that some of the 'shoplifting alarm tags' work. (ie, each tag has a small rf diode, which reflects rf energy, provided by the sensor at the door). George Tzanatos.
