Diagnostic steps for resolving Poynt Terminal prepaid card validation failures. Focus: External fixes, cable strain, ESD, and contactless reliability.
Navigate to the settings menu and select 'About' to find the firmware version.
Test with several different card types to isolate the issue to prepaid cards.
Moisture can damage the internal components and affect card reader performance.
EMV and NFC readers communicate via radio frequency (13.56 MHz). Signal attenuation can occur due to interference or component degradation. Contactless payment failures may also be caused by voltage irregularities, electrostatic discharge (ESD), or firmware issues affecting card validation protocols. Baud rate mismatches in the card reader's data transmission can lead to incomplete or corrupted data transfer during the card reading process.
The Poynt Terminal fails to validate prepaid cards during transactions. Other card types may function correctly. Error messages may vary or the transaction may simply fail.
Do not attempt to open or disassemble the Poynt Terminal. Doing so will void the warranty and potentially trigger anti-tamper mechanisms, rendering the device unusable. Ensure the terminal is placed on a stable and dry surface to prevent accidental spills and electrical hazards. Avoid using the terminal during electrical storms. If the terminal is damaged, contact authorized Poynt support for assistance.
Regularly clean the terminal's exterior with a dry, anti-static cloth. Minimize cable strain by ensuring cables are properly routed and supported. Implement grounding straps to mitigate ESD, especially during dry winter months. Schedule routine firmware updates. Train staff on proper card insertion and removal techniques to avoid damaging the card reader.
Try performing a 'soft reset' by holding the power button down for 10-15 seconds. This can sometimes clear minor software glitches affecting card validation. If issues persist, check the Poynt HQ portal for reported service outages affecting prepaid card processing.
