Diagnostic report for Clover Flex displaying 'Invalid PIN' after Scotiabank app crashes. Focus on non-invasive troubleshooting and safety.
Document any physical damage for potential warranty claims.
If so, the problem may be network-related or a widespread software bug.
Extreme temperatures or low humidity can affect device performance.
The Clover Flex PIN entry process involves secure cryptographic key exchange between the device, the payment application (Scotiabank app), and the payment processor. App crashes can interrupt this key exchange or corrupt the PIN pad buffer. Insufficient voltage, especially during peak transaction times, can also cause intermittent failures. ESD (electrostatic discharge) from user interaction, particularly in dry environments, can disrupt the touchscreen and PIN pad circuitry. The device relies on serial communication with the payment processor; signal attenuation or data corruption can lead to transaction failures.
High voltage is present within the power adapter. 'Safe Handling' requires unplugging the device before any physical inspection. Electrostatic discharge (ESD) can damage the device. Ground yourself before touching the touchscreen, especially in dry environments. Do not attempt to open the Clover Flex casing; this will trigger anti-tamper mechanisms and permanently disable the device.
Regularly clean the touchscreen with a soft, dry, anti-static cloth. Avoid using excessive moisture or harsh chemicals.,Ensure the Clover Flex is connected to a stable power source with surge protection.,Implement cable strain relief measures to prevent damage to the power and communication cables.,Periodically check for and install software and firmware updates.,Use a small, portable humidifier near the checkout area, especially during dry winter months, to reduce electrostatic discharge.
Try performing a 'soft reset' by pressing and holding the power button and the volume down button simultaneously for approximately 10 seconds. This may clear temporary software glitches without wiping data. A failing power adapter can cause intermittent 'Invalid PIN' errors. Test with a known good adapter of the same voltage and amperage.
