- Cracked Solder Joints: The internal parts are soldered to the circuit board. Bending the card causes these small solder indicate fracture, breaking the electrical connection.
- Loose Microswitches: The physical buttons inside the card can separate from the board.
- Battery Exhaustion: The internal battery (normally a CR2032 or CR2016 cell) eventually dies, cutting power to the transponder and remote transmitter.
- Ecological Damage: Exposure to wetness, extreme heat, or being dropped on tough surface areas can permanently damage the sensitive electronic devices within.
