Bob,
Passive tags that are energized by an impending RF field are usually not considered transmitters. This is because they return their data by loading and unloading the impending RF field; this is sometimes termed "backscatter". This type of passive tag does not fall under the R&TTE Directive. Active tags that have their own oscillator and transmitter, however, need to meet R&TTE Directive requirements.

But it is my understanding that the passive tags are not subject to RTTE. We need someone who knows for sure to respond.

These types of tags are powered by a received signal, may receive a coded signal, and they respond with a coded signal. They are obviously very low power devices and the transmit power is far below that of their interrogator. But the nagging fact remains that they are transponders.
