Clover Mini 'Tamper Error' troubleshooting after suspected physical shock. Focus on external solutions, safety, and error prevention in a retail environment.
Document if any power issues occurred.
Check other terminals and peripherals for malfunction.
Record any prior physical stress events.
The Clover Mini utilizes internal tamper-detection mechanisms (e.g., mesh networks, accelerometers) to protect sensitive cryptographic keys and payment card data. These mechanisms are designed to trigger upon physical intrusion, voltage fluctuations, or unexpected acceleration. When triggered, the device enters a secure, locked state. The 'Tamper Error' indicates that one or more of these mechanisms has been activated. Voltage dips during a shock can also trigger the error.
The Clover Mini is a sensitive electronic device. Avoid applying excessive force or pressure to the device. Do not attempt to open or disassemble the device, as this will void the warranty and may trigger irreversible tamper protection mechanisms. Safe Handling: Always disconnect the power supply before inspecting or manipulating cables. Avoid exposing the device to liquids or extreme temperatures. Do NOT attempt Lockout/Tagout (LOTO) procedures.
Secure the Clover Mini to a stable surface to prevent accidental falls or impacts.,Use cable management solutions to minimize cable strain and prevent accidental disconnections.,Implement ESD control measures, such as grounding mats and anti-static wrist straps, particularly during dry seasons.,Ensure the device is connected to a stable and reliable power source, ideally with surge protection.,Regularly clean the touchscreen with a manufacturer-approved cleaning solution to prevent debris buildup and ensure optimal operation.,Periodically check for and apply firmware updates provided by Clover to address potential security vulnerabilities and improve device stability.
In some instances, a 'Tamper Error' can be triggered by a momentary voltage dip. After Safe Handling (unplugging), leave the device disconnected from power for at least 15 minutes. This allows any residual charge to dissipate. Then, reconnect the power and attempt to boot the device. This can sometimes clear the error if it was caused by a transient event.
