Diagnostic report for PAX G10-S 'Invalid Payment Type' error. Covers symptoms, causes, safe solutions, prevention, and safety warnings for retail environments.
This helps determine if physical damage or incorrect settings are the cause.
Indicates a potential network or processor issue rather than a terminal-specific problem.
Helps narrow down the potential causes (e.g., NFC issues vs. EMV issues).
Payment terminals communicate with payment processors using defined protocols. This involves data transmission over serial lines (USB or dedicated serial) using specific baud rates and voltage levels. EMV (chip card) transactions rely on a secure element within the terminal to encrypt and transmit data. NFC transactions rely on antenna integrity. Software configuration dictates the accepted payment types. Electrical noise (EMI) or electrostatic discharge (ESD) can disrupt these processes. Voltage fluctuations can also impact device operation.
Electrostatic discharge (ESD) can damage the terminal's internal components. Avoid touching the terminal with bare hands after contact with materials that generate static electricity. Ensure cables are properly connected and do not pose a tripping hazard. Do not attempt to open or modify the terminal, as this will void the warranty and may damage the device. Safe Handling: Unplug the device from the power source before cleaning or inspecting cables.
Regularly clean the terminal's exterior with a soft, dry cloth to prevent dust buildup. Avoid using excessive moisture or harsh chemicals.,Implement cable strain relief measures to prevent damage to the USB cable and connectors. Ensure the cable is not bent or stretched excessively.,Ground the terminal appropriately to minimize the risk of electrostatic discharge. Use anti-static mats in dry environments.,Periodically check for and install firmware updates provided by PAX to address known issues and improve performance.,Ensure the terminal is placed in a location with adequate ventilation to prevent overheating.
If the 'Invalid Payment Type' error occurs intermittently, check the terminal's logs for any error messages related to specific payment methods or communication failures. These logs can provide valuable insights into the root cause of the issue. Try a different USB port on the host system to rule out port-related issues.
