Troubleshooting G-13 terminal coin rejection issues. Focus on external factors: bezel damage, ESD, EMI. Non-invasive solutions only.
Use an antistatic wipe or a solution of isopropyl alcohol diluted with distilled water.
Try relocating the terminal and observing if the issue persists. Common sources include power supplies, fluorescent lights, and radio transmitters.
Consult the terminal's user manual or contact technical support for instructions.
EMV/NFC card terminals are susceptible to external interference. Damaged coin entry bezels can introduce electrostatic discharge (ESD) or electromagnetic interference (EMI), disrupting sensor readings. Internal voltage fluctuations or baud rate errors can also occur due to damaged external components. Sensor degradation can falsely flag valid coins. The touchscreen controller might be affected by nearby electrical noise or physical damage. Power supply instability is a common trigger of this type of error.
Static electricity can damage electronic components. Avoid touching internal components. Safe Handling procedures: Unplug the device from the power source before cleaning or inspecting cables. Ensure the work surface is dry.
Regularly clean the coin entry bezel with an antistatic wipe.,Ensure adequate spacing between the terminal and other electronic devices.,Use a surge protector to stabilize the power supply.,Train staff on safe handling practices to minimize electrostatic discharge.,Inspect the power cable for strain or damage.
High humidity reduces ESD events. In dry environments (winter), use a humidifier or antistatic spray nearby (but not directly on) the terminal. A ferrite choke on the power cord might reduce EMI.
