G-13 Card Terminal: Vandalism Resistance Assessment and... | terminalfaults.org

Technical Background:

Card terminals, particularly in unattended environments, are susceptible to physical attacks aimed at bypassing security measures or extracting sensitive data. Vulnerabilities include physical access to communication ports (USB, Ethernet), susceptibility to electrostatic discharge (ESD) from external sources, and disruption of NFC/EMV antenna integrity. Signal attenuation due to physical damage can degrade transaction reliability. Extreme temperatures (-40C) can affect component performance and battery life (if applicable).

Symptoms:

Observed device damage indicates attempted or successful physical compromise. Specific damage details are unavailable but presumed to include casing damage, button malfunction, or screen damage.

Possible Causes:

Physical impact resulting in damage to internal components.
Electrostatic discharge (ESD) causing electronic malfunction or data corruption.
Exposure to extreme temperatures outside of operational specifications.
Tampering with communication ports (USB, Ethernet) to inject malicious code or extract data.
Damage to the NFC/EMV antenna affecting contactless transaction capability.
Casing compromise leading to exposure of internal components to environmental factors.

Solution:

1

Perform a visual inspection of the G-13 terminal, documenting any physical damage.
2

Verify network connectivity by attempting a test transaction.
3

Test all input methods (keypad, NFC/EMV reader) to ensure functionality.
4

Examine communication ports (USB, Ethernet) for signs of tampering or physical damage.
5

Using a regulated ESD-safe vacuum, clean the exterior of the device to remove any debris or contaminants.
6

If the device is battery-powered, assess battery health and consider replacement if necessary (if user-replaceable externally).
7

Consult the manufacturer's datasheet for the G-13's operational temperature range and ensure the kiosk environment remains within those limits.

Safety Warning:

Safe Handling Procedures: Prior to any inspection or maintenance, power down the G-13 terminal by disconnecting it from the power source. Ensure hands are dry and the work surface is clean and dry. Avoid contact with exposed electronic components. Do not attempt to open the device casing.

Prevention:

Implement a routine cleaning schedule to remove dust and debris.,Ensure proper cable management to prevent strain and potential damage to communication ports.,Consider installing a protective enclosure around the terminal to mitigate physical impact.,Regularly update the terminal's firmware to patch security vulnerabilities.,Monitor transaction logs for suspicious activity.,Implement environmental controls (heating/cooling) to maintain operational temperature range.

Expert Tip:

Apply an external ferrite choke to the power cable and any communication cables close to the terminal. This can help mitigate electromagnetic interference (EMI) that may affect transaction reliability, especially in environments with high levels of electrical noise.
