11. A method of transmitting a information set from a wireless tag to a wireless tag reader/writer, comprising the steps of:
-
detecting physical stimulus in and/or around the wireless tag to generate a detected information set by a sensor of the wireless tag;
storing the detected information set to a storage of the wireless tag;
evaluating, at the wireless tag, the detected information set on the basis of a criteria information set, which is previously transmitted to the wireless tag, to generate a determination result information set; and
transmitting the determination result information set from the wireless tag to the wireless tag reader/writer.
