An RFID device includes a first, relatively permanent portion and a second
alterable or inactivatable portion. Upon the occurrence of some
predetermined event, the second portion and/or its coupling to the first
portion is physically altered, inactivating it. The first portion may
itself be an antennaless RFID device that may be read at short range, and
the second portion may be an antenna that, when coupled to the first
portion, substantially increases the range at which the first portion may
be read. The second portion may be configured to be altered or
inactivated by any of a variety of predetermined events, such as
involving physical, chemical or electrical forces, performed either on
the RFID device, or upon an object to which the RFID device is coupled.
