Technical analysis of Opus terminal rejecting cards with bent corners. Focus: NFC/EMV failure, possible causes, solutions, and preventive measures for unattended kiosks.
Refer to the Opus Terminal technical specifications.
Inspect the power supply specifications and consider adding an external surge protector.
Check the purchase documentation or contact Opus support.
EMV chip card readers rely on precise physical contact between the card's chip and the reader's contacts. NFC (Near Field Communication) relies on radio frequency signal transmission over a short distance. Slight card deformation can alter chip contact pressure or increase the distance/angle for NFC, leading to signal attenuation or failed chip engagement. Environmental factors (temperature variations) can also affect the reader's physical tolerances and sensitivity.
Implement regular cleaning schedule for the terminal exterior using a damp cloth. Avoid using abrasive cleaners.,Ensure the terminal is installed in a location protected from direct sunlight and extreme weather conditions.,Inspect and secure all cable connections to prevent accidental disconnections or strain.,Provide signage discouraging the use of damaged or excessively bent cards.,Periodically inspect the card reader slot for debris and clean as needed using compressed air.,Monitor terminal power supply voltage for stability. Install a surge protector to mitigate voltage spikes.
Try slightly varying the card insertion speed during EMV transactions. A slower, more deliberate insertion may improve contact. For NFC failures, ensure the card is held flat and still against the reader surface for a longer duration.
