Diagnosing Poynt Terminal tamper alerts. Review technical causes, safe solutions, and preventative maintenance to minimize downtime. Avoid internal modification.
Using a non-certified adapter can lead to voltage irregularities and trigger tamper alerts.
Impact can damage internal sensors and trigger tamper detection.
New sources of EMI might be interfering with the device's operation.
The Poynt Terminal employs physical and logical tamper detection mechanisms according to PCI-PTS standards. These mechanisms monitor voltage, current, temperature, and physical intrusion. A tamper event triggers a secure memory wipe or disables cryptographic functions. Erroneous alerts can arise from ESD events or power fluctuations, corrupting the tamper detection logic.
Poynt Terminal displays a 'Tamper Alert'. The device is non-operational and prevents payment processing.
The Poynt Terminal is a PCI-PTS secured device. Do not attempt to open or disassemble the terminal. Such actions will trigger the tamper mechanism and permanently render the device inoperable. Ensure the power cable is undamaged to prevent electrical hazards. Safe Handling (unplugging) is the recommended procedure. Avoid water or liquids near the terminal.
Implement ESD prevention measures, especially during dry conditions. Use anti-static mats and wrist straps when handling the terminal.,Ensure a stable power supply. Use a surge protector to safeguard against voltage spikes.,Position the terminal away from sources of electromagnetic interference (e.g., microwave ovens, wireless routers).,Clean the touchscreen regularly with a dry, lint-free cloth. Avoid excessive moisture.,Provide adequate strain relief for all connected cables to prevent damage to connectors.
In some cases, a persistent tamper alert might be cleared by performing a factory reset via a specific key combination (consult Poynt documentation). However, proceed with caution as this may erase transaction history. Back up any crucial data before attempting a reset. A failing internal battery can cause spurious tamper alerts; monitoring the battery health in the device settings (if accessible) can provide clues.
