Diagnosing Poynt terminal voucher validation issues in a retail environment. Focus on external causes and safe handling procedures.
Recent updates can introduce new bugs or compatibility issues.
A widespread issue may indicate a network or server problem.
The error message can provide clues about the root cause of the problem.
Voucher validation relies on data transmitted via NFC or EMV. Signal attenuation, voltage fluctuations, or software errors can interrupt the validation process. The terminal's security module must correctly process and transmit the voucher data to the payment processor. Power fluctuations can corrupt in-memory processes. The baud rate of the serial connection with external systems must be stable.
Terminal fails to validate meal vouchers. Transactions are declined or produce an error message related to voucher authorization. No physical damage observed.
Handle the terminal with care. Avoid dropping or subjecting it to physical shock. Do not attempt to open the terminal casing; this will trigger the anti-tamper mechanism and render the device unusable. Safe Handling: Unplug the terminal from the power outlet before cleaning. Ensure your hands are dry to avoid electrical shock.
Regularly clean the touchscreen with a soft, dry cloth to remove smudges and contaminants. Ensure cables are properly connected and not subjected to strain. Place the terminal away from sources of electromagnetic interference (e.g., microwave ovens, radio transmitters). Consider using a surge protector to prevent power fluctuations.
