Diagnose Poynt terminal payment integration issues. Focus on external connectivity, software updates, and environmental factors impacting NFC/EMV functionality.
Verify network connectivity via Ethernet or Wi-Fi. Ping a known external address.
Check for and install any available software or firmware updates.
Review the terminal's configuration to ensure the problematic payment methods are activated.
Payment integration relies on proper communication between the terminal's NFC/EMV reader, the payment processing software, and the backend payment gateway. Voltage fluctuations, signal attenuation due to cable damage, electrostatic discharge (ESD), or software conflicts can disrupt this process. NFC operates at 13.56 MHz. Signal degradation at this frequency may be due to external interference. Incorrect configurations in the terminal’s firmware or outdated payment processing libraries are possible software failure points.
Do not attempt to open or disassemble the terminal. Doing so may damage the device and void any warranties. Static electricity can damage electronic components. Ground yourself before touching the terminal or cables, especially in dry environments. Ensure the terminal is placed on a stable, dry surface to prevent accidental spills or damage.
Regularly clean the terminal's touchscreen with a soft, dry cloth to remove dirt and fingerprints. Inspect cables for damage and ensure they are properly secured to prevent strain. Avoid placing the terminal near sources of electromagnetic interference. Keep terminal software updated to the latest version.
Some Poynt terminals have a diagnostic mode accessible via a specific key combination (check official Poynt documentation). This mode can provide detailed information about the terminal's hardware and software status. Use a ferrite choke on the power cable to reduce potential EMI.
