Over time, this mechanical stress leads to:
- Cracked Solder Joints: The internal parts are soldered to the circuit board. Flexing the card triggers these small solder indicate fracture, breaking the electrical connection.
- Loose Microswitches: The physical buttons inside the card can detach from the board.
- Battery Exhaustion: The internal battery (typically a CR2032 or CR2016 cell) ultimately passes away, cutting power to the transponder and remote transmitter.
