Ingenico iCT220 Tamper Error Diagnostic Report - Solar... | terminalfaults.org

Technical Background:

The iCT220 incorporates a secure cryptographic module and tamper detection circuitry as mandated by PCI-PTS standards. Activation of a tamper sensor results in a non-recoverable error state to protect sensitive cryptographic keys and payment card data. Common triggers include voltage spikes, physical intrusion attempts, and ESD events exceeding the device's protection threshold.

Symptoms:

The Ingenico iCT220 displays a "Tamper Error" message. This error occurred following a suspected attempt to bypass the PIN entry process.

Possible Causes:

Physical Tampering: Direct attempt to access internal components or circuitry.
Voltage Surge: External power fluctuations exceeding the device's tolerance.
Electrostatic Discharge (ESD): High-voltage static discharge during PIN entry.
Firmware Corruption: Interruption of the firmware update process.
Hardware Failure: Component failure within the tamper detection circuitry.
Environmental Factors: Extreme temperature or humidity causing sensor malfunction.

Solution:

1

Safe Handling: Disconnect the iCT220 from its power source and network connections.
2

Visual inspection: Check for any signs of physical damage to the device casing, ports, or cables.
3

External Cleaning: Gently clean the device exterior with a dry, anti-static cloth. Pay attention to the PIN pad and card reader slot.
4

Power Cycle: Reconnect the power cable and observe if the error persists. Ensure the power supply is functioning correctly.
5

Network Connectivity Check: Verify the network cable is securely connected and the network connection is active.
6

Contact Support: If the error persists after power cycling, contact Ingenico support or an authorized service provider for assistance. Provide them with the error message and any relevant details.
7

Consider Replacement: In cases of confirmed tampering, replacement of the terminal may be necessary to maintain PCI compliance.

Safety Warning:

Potential hazards include electrical shock and ESD. Always disconnect the device from the power source before cleaning or inspecting cables. Do NOT attempt to open or repair the device yourself as this will void the warranty and trigger the tamper detection mechanism, rendering the device unusable. Ensure the device is placed on a dry, non-conductive surface during troubleshooting. Safe Handling: Always unplug the device before inspection.

Prevention:

Implement regular cleaning schedules for the terminal, paying close attention to the PIN pad.,Use a surge protector to safeguard against voltage fluctuations.,Implement static control measures, especially during dry winter months (e.g., anti-static mats, grounding straps).,Train staff on proper PIN entry procedures and the importance of preventing physical tampering.,Ensure firmware updates are performed according to manufacturer instructions.,Inspect cables regularly for signs of wear or damage and replace them as needed.

Expert Tip:

Try holding down the '#' key while powering on the device. This may sometimes initiate a diagnostic mode or clear minor software glitches. However, note that this is NOT a guaranteed solution for tamper errors and may not be available on all iCT220 firmware versions. If that doesn't work, note the exact timestamp of the failure (if available in logs) for submission to the payment provider's fraud department.

Frequently Asked Questions

•What are the steps for cleaning the iCT220 terminal?

Disconnect the terminal from power. Use a dry, anti-static cloth to wipe the exterior, focusing on the PIN pad and card reader. Avoid using liquids or abrasive cleaners.

•How can I protect the terminal from voltage surges?

Use a surge protector power bar. Ensure the surge protector is rated to handle the terminal's power requirements.

•What are the signs of physical tampering?

Look for scratches, dents, loose screws, or any other evidence of forced entry on the terminal casing or card reader slot.
