Indicates a potential misconfiguration issue.
EMV/NFC transactions require secure key exchange and authorization. Software logic dictates transaction type. Failure points can include corrupted application data, incorrect terminal configuration, or communication errors between the terminal and the payment processor. Voltage fluctuations, ESD events, or signal attenuation due to cable damage can disrupt data transmission. Secure boot processes verify software integrity; failure can disable functionalities.
The TD terminal is unable to process refund transactions. Refund functionality is reported as disabled.
Safe Handling: Always unplug the terminal from the power outlet before performing any inspection or cleaning. Avoid using excessive force on any components. Do not attempt to open the terminal casing. ESD (Electrostatic Discharge) is a risk, particularly in dry environments. Ground yourself before touching the terminal. Do not use flammable or corrosive cleaning agents.
Regularly clean the terminal's exterior with an approved electronic device cleaner.,Implement cable strain relief measures to prevent cable damage.,Ensure the terminal is placed on a stable surface away from potential sources of liquid spills.,Consider using a surge protector to protect the terminal from voltage fluctuations.,Periodically check for and install terminal software updates.,Train staff on proper terminal handling procedures, including avoiding excessive force on the touchscreen.
Attempt a 'soft reset' by holding down the power button for 10 seconds. This can clear temporary memory issues without affecting configuration settings. If the issue persists, document the exact steps leading up to the error. Note any specific error codes displayed on the screen.
