Abstract
An RFID tag can include a transmitting device and a receiving device for transmitting data to and receiving data from a tag reader, and the tag can include a memory for storing identification data unambiguously labeling the RFID tag and circuitry which automatically executes functions depending on the fact that: the reader demonstrates knowledge of an internal password in a memory of the tag; and information stored in the memory of the tag for an internal state permits the execution of the function. The tag also includes circuitry for changing the stored password and/or the internal state, in particular depending on a previous comparison of the internal password to one received from the reader.
