PAX G10-S NFC Payment Failure Diagnostic Report - Solar... | terminalfaults.org

Technical Background:

NFC (Near Field Communication) operates on a 13.56 MHz radio frequency. The antenna radiates this signal to communicate with payment cards or mobile devices. Signal attenuation can occur due to cable strain, external interference, or internal hardware degradation. The terminal's firmware controls the NFC reader's power output and data processing. Electrostatic discharge (ESD) can damage the antenna or associated circuitry.

Symptoms:

The PAX G10-S terminal fails to process contactless payments via NFC. Contactless card taps and mobile wallet transactions are not recognized or result in error messages. The terminal may function correctly for chip-and-PIN transactions.

Possible Causes:

Damaged or loose NFC antenna cable connection inside the terminal (though DO NOT open the terminal due to anti-tamper mechanisms).
External electromagnetic interference (EMI) from nearby devices affecting the 13.56 MHz frequency.
Software or firmware malfunction causing incorrect NFC initialization or operation.
Electrostatic discharge (ESD) damage to the NFC antenna or control circuitry.
Cable strain on the terminal's power or communication cables, leading to intermittent NFC operation.
Degradation of the NFC antenna due to age or environmental factors (humidity, temperature fluctuations).

Solution:

1

Inspect the terminal's external power and communication cables for any signs of damage or strain. Ensure they are securely connected.
2

Power cycle the terminal by disconnecting and reconnecting the power cable. Wait 30 seconds before reconnecting.
3

Clean the terminal's touchscreen and surrounding areas with a clean, dry, antistatic cloth to remove any contaminants that may be interfering with the NFC reader.
4

Verify that the terminal is running the latest firmware version. Contact your payment processor or PAX support for firmware updates.
5

Move any nearby electronic devices that may be causing electromagnetic interference (EMI) away from the terminal.
6

Test the terminal with multiple contactless cards and mobile devices to rule out issues with specific payment methods.
7

If the problem persists, contact PAX support or a certified technician for further assistance.

Safety Warning:

To prevent electrical shock, always disconnect the power cable before cleaning the terminal. Do not use excessive force when connecting or disconnecting cables. Handle the terminal with care to avoid dropping or damaging it. Safe Handling: Unplug the device from the power source before any external inspection. Ensure your workspace is dry.

Prevention:

Regularly clean the terminal's exterior with an antistatic cloth. Ensure cables are properly routed and secured to prevent strain. Protect the terminal from electrostatic discharge, especially in dry environments. Keep the terminal away from sources of electromagnetic interference. Periodically check for and install firmware updates.

Expert Tip:

Try performing a 'cold boot' by holding down the power button for 15 seconds while the terminal is unplugged. This fully discharges the internal capacitors and can sometimes resolve firmware glitches affecting the NFC reader. An external USB ferrite choke on the power cable might mitigate EMI issues.

Frequently Asked Questions
