Diagnostic report for TD terminal discount card errors. Includes symptom analysis, potential causes, solutions, prevention, and safety warnings.
This could highlight recent software changes causing the issue.
If other cards read correctly, the problem likely resides with the discount card or its integration.
The error message can provide clues about the specific failure point.
EMV/NFC transactions rely on radio frequency identification (RFID) at 13.56 MHz. Signal attenuation due to interference or a faulty antenna can disrupt card reads. Software integration requires correct data formatting and transmission between the terminal and the discount program server. Static discharge (ESD) can corrupt the card reader's memory or communication interface. The baud rate for the serial communication port may be incorrectly configured.
Terminal failing to process employee discount cards. Indicates potential issue with card reader, software integration, or card data.
Safe Handling: Always unplug the terminal before cleaning or inspecting cables. Avoid operating the terminal in wet or humid conditions. Static discharge can damage electronic components. Use caution during dry winter months when static electricity is more prevalent. Never attempt to open the terminal's casing, as this may trigger anti-tamper mechanisms and void the warranty. Ensure adequate ventilation around the terminal to prevent overheating.
Regularly clean the card reader using a dry, lint-free cloth. Implement cable strain relief measures to prevent damage to the cable connections. Periodically check for software updates from TD. Maintain a consistent humidity level to minimize the risk of ESD. Ensure proper grounding of the terminal and surrounding equipment.
Try swiping the card multiple times at different speeds. A slightly slower or faster swipe may improve the read success rate. If the issue persists, use a USB keyboard to manually enter the discount code to bypass the card reader as a temporary workaround.
