Hyosung Halo II: Investigating False Tamper Alerts -... | terminalfaults.org

Technical Background:

The Halo II's tamper detection system relies on a network of sensors monitoring voltage, current, and physical integrity. Erroneous signals from these sensors can trigger a false positive. Signal attenuation in communication cables can disrupt sensor feedback loops. Electrostatic discharge (ESD) events and voltage fluctuations can corrupt the tamper detection logic. Low temperatures (-40C) may affect the sensor's sensitivity.

Symptoms:

The Hyosung Halo II reports a 'Tamper' error without physical evidence of intrusion. The error persists despite multiple power cycles. Transaction processing is disabled due to the tamper flag.

Possible Causes:

Voltage fluctuations from the power supply causing erratic sensor readings.
Electrostatic discharge (ESD) near the card reader affecting sensor circuits.
Degraded or damaged communication cables (USB, serial) causing signal loss.
Loose or corroded connector pins leading to intermittent sensor disconnections.
Extreme temperature (-40C) impacting the sensitivity of tamper detection sensors.
Software corruption affecting the interpretation of sensor data.

Solution:

1

Power cycle the Halo II and the host system (kiosk). Wait 60 seconds before restoring power.
2

Inspect all external cables (USB, serial, power) for damage or wear. Replace any suspect cables.
3

Check cable connections at both the Halo II and the host system. Ensure they are securely seated.
4

Verify the input voltage to the Halo II power supply is within the specified range (typically 12V or 24V DC). Use a multimeter.
5

Examine the area surrounding the Halo II for potential sources of ESD, such as static-generating materials. Reduce static electricity.
6

If possible, temporarily relocate the kiosk to a location with a more stable power supply to rule out power fluctuations.
7

Contact Hyosung technical support for firmware update verification or diagnostic tool access (if available).

Safety Warning:

Handle the Hyosung Halo II with care to avoid electrostatic discharge (ESD). Always disconnect the power supply before inspecting cables or connections. Ensure the device is placed on a stable, dry surface. Do not expose the device to excessive moisture or extreme temperatures. Safe Handling (unplugging, dry surface) is paramount.

Prevention:

Regularly inspect external cables for wear and tear. Ensure proper cable strain relief to prevent connector damage. Clean the card reader's exterior with a dry, non-abrasive cloth. Monitor the ambient temperature and humidity to ensure they are within the device's operating specifications. Implement surge protection for the power supply.

Expert Tip:

Before replacing the Halo II, try connecting it to a different host system with a known good power supply and cable. This can quickly isolate whether the issue is with the card reader itself or with the kiosk's power or communication infrastructure.
