An improved identification band such as a wristband or the like is provided of the type including a radio frequency identification (RFID) circuit for communicating wearer information with a remote reader. A pair of electronic coupling elements such as capacitor plates are formed at opposite head and tail ends of the identification band, and are adapted for adhesive securement in mutually coupled relation to enable the RFID circuit with a predetermined circuit resonance frequency fortuned communication with the remote reader. Upon attempted separation of the band head and tails ends, for removal of the identification band from the wearer, one or both of the coupling elements is physically distorted to alter the circuit resonance frequency, thereby detuning the circuit and preventing subsequent communication with the remote reader.
