Recent changes may have introduced a software conflict.
Employee discount cards likely utilize NFC or EMV chip technology. Failure points can stem from reader module malfunction, signal attenuation, incorrect card orientation/placement, software configuration errors, or external interference (EMI/ESD). Baud rate mismatches between the terminal and the card, or voltage fluctuations, can also cause read errors.
High voltage is present inside the terminal enclosure. DO NOT attempt to open the device. Doing so will void the warranty and may trigger anti-tamper mechanisms, rendering the device unusable. Safe Handling: Always unplug the terminal from the power source before performing any external cleaning or maintenance.
Regularly clean the card reader surface. Implement cable strain relief measures (e.g., cable ties) to prevent connector damage. Minimize static electricity buildup, especially during dry winter months, by using anti-static mats and sprays near the terminal.
Try performing a 'cold boot' of the terminal (power off, wait 30 seconds, power on). This can sometimes clear persistent software glitches. If the terminal has a diagnostic menu (consult the user manual, or contact TD tech support), use it to check the reader module's status.
