Halo II Card Reader Tamper Error: Cleaning and... | terminalfaults.org

Technical Background:

PCI-PTS certified card terminals employ internal anti-tamper mechanisms. These are triggered by physical intrusion, voltage fluctuations, or electrostatic discharge (ESD). The 'Tamper' error indicates that one or more sensors have been activated. Erroneous sensor triggering can occur due to environmental factors or hardware degradation. Voltage fluctuations during power cycles or ESD events during dry months may falsely trigger the anti-tamper system. Accumulation of dust or contaminants on the exterior surfaces, particularly around the card reader slot and cable connections, can contribute to signal interference.

Symptoms:

The Halo II card reader displays a 'Tamper' error message, preventing normal transaction processing.

Possible Causes:

Electrostatic Discharge (ESD) event.
Voltage spike or power surge.
Loose or damaged cable connections.
Accumulation of dust or debris on the card reader surface.
Internal hardware failure (anti-tamper trigger activated).
Software corruption or firmware issue.

Solution:

1

Safe Handling: Disconnect the Halo II card reader from the power source and network connection.
2

Visual inspection: Examine the card reader for any signs of physical damage, such as cracks or loose components.
3

Cable Check: Inspect all cables connected to the card reader for damage, bends, or loose connections. Ensure proper seating and secure connections.
4

Cleaning: Use a clean, dry, lint-free cloth to gently wipe the exterior surfaces of the card reader, including the card swipe slot. Do not use liquid cleaners or solvents.
5

Power Cycle: Reconnect the power source and network connection. Observe if the 'Tamper' error persists.
6

Test Transaction: Attempt a test transaction using a valid test card to verify functionality.
7

Contact Support: If the error persists after performing these steps, contact the manufacturer's technical support for further assistance.

Safety Warning:

Do not attempt to open the card reader casing. This will void the warranty and potentially trigger the anti-tamper mechanisms, rendering the device permanently unusable. High voltage power supplies are used internally. Safe Handling procedures MUST be followed when disconnecting/reconnecting the device. Do not use excessive force when connecting cables.

Prevention:

Regular cleaning of the card reader and surrounding area. Implement cable strain relief measures to prevent damage to cable connections. Use an Uninterruptible Power Supply (UPS) to protect against voltage spikes and power surges. Grounding straps should be provided for checkout staff to discharge ESD before handling the device in colder and dryer months (if feasible).

Expert Tip:

Check the card reader's firmware version. An outdated firmware version might be the cause of false 'Tamper' errors. Refer to the manufacturer's website for instructions on how to update the firmware. Some card readers have a diagnostic mode accessible via a specific key combination (refer to the manufacturer's documentation).

Frequently Asked Questions

•What type of cleaning cloth is recommended for the card reader?

A clean, dry, lint-free microfiber cloth is recommended to avoid scratching the surface and leaving residue.

•How often should the card reader be cleaned?

The card reader should be cleaned at least once a week, or more frequently if it is used in a high-traffic area.

•What is the typical lifespan of this device and how can one maximize it?

The lifespan varies based on usage, but typically 3-5 years. Regular cleaning, cable strain relief, and surge protection will extend device life.
