Cracked Solder Joints: The internal components are soldered to the circuit board. Flexing the card triggers these tiny solder points to fracture, breaking the electrical connection.

Battery Exhaustion: The internal battery (generally a CR2032 or CR2016 cell) ultimately dies, cutting power to the transponder and remote transmitter.
