Poynt Terminal Rebooting After NFC Transaction:... | terminalfaults.org

Technical Background:

NFC (Near Field Communication) chips operate on a 13.56 MHz radio frequency. Signal attenuation can occur due to interference, physical damage to the antenna, or voltage fluctuations affecting the NFC controller. Rebooting suggests a critical system error due to the interrupted transaction. ESD events are common in retail environments, especially during dry winter conditions, and can disrupt sensitive electronic components.

Symptoms:

Terminal reboots after attempting an NFC transaction (Interac tap). The system becomes unresponsive, followed by an automatic restart.

Possible Causes:

Cable strain on the power supply or data connection causing intermittent voltage drops during NFC transactions.
Electrostatic discharge (ESD) near the NFC antenna or touchscreen.
Firmware corruption affecting NFC transaction processing.
Hardware failure of the NFC chip or related components (antenna, controller).
Electromagnetic interference (EMI) from nearby devices affecting NFC signal integrity.
Inadequate power supply, failing to provide sufficient power during the NFC transaction.

Solution:

1

Safe Handling: Disconnect the terminal from its power source.
2

Inspect all cable connections (power, network) for damage or loose connections. Reseat the cables firmly.
3

Clean the touchscreen with a dry, anti-static cloth to remove any surface contaminants that may be causing interference.
4

Check the power adapter's voltage output with a multimeter (if available) to ensure it meets the terminal's specifications. Replace if necessary.
5

Relocate the terminal away from potential sources of EMI (e.g., other electronic devices, power cords).
6

If available, perform a software update to the latest firmware version through the terminal's settings menu.
7

If the problem persists, contact Poynt support for advanced diagnostics or hardware repair.

Safety Warning:

Potential hazards include electric shock from damaged power cables. Ensure the terminal is disconnected from the power source before inspecting cables. ESD can damage the terminal's components. Use anti-static precautions. Do NOT attempt to open the terminal casing; this may trigger anti-tamper mechanisms and void the warranty.

Prevention:

Implement cable strain relief measures to prevent damage to power and data cables.,Use anti-static mats and wrist straps during handling and maintenance to minimize ESD risks.,Regularly clean the touchscreen with a dry, anti-static cloth.,Ensure the terminal is connected to a dedicated, stable power outlet.,Keep the terminal away from sources of electromagnetic interference.,Periodically check for and install firmware updates provided by Poynt.

Expert Tip:

Try performing a 'soft reset' of the terminal by holding down the power button for 10-15 seconds. This can sometimes clear temporary software glitches. Also, a ferrite choke on the power cable might reduce EMI. Check the firmware version and release notes for known NFC issues.
