Troubleshooting Interac Flash payment failures on Ingenico iCT220 terminals. Focus on software updates, contactless reader issues, and ESD prevention.
Locate the software version in the terminal's system information menu.
Check the update history or contact the service provider for update logs.
Compare performance across multiple terminals to identify a widespread issue.
Interac Flash transactions rely on near-field communication (NFC) operating at 13.56 MHz. Signal attenuation due to interference or a malfunctioning antenna can cause failures. Software updates can introduce compatibility issues with specific card types or NFC protocols. Electrostatic discharge (ESD) can damage the NFC reader or related circuitry.
Safe Handling: Always unplug the terminal from the power source before cleaning or inspecting cables. Avoid using excessive force when connecting or disconnecting cables. Do not attempt to open the terminal casing, as this may damage the device and void the warranty. Electrostatic Discharge (ESD) is a significant risk, especially during dry winter months. Use antistatic wrist straps when handling the terminal if available. Ensure the surrounding area is free of static-generating materials.
Regularly clean the terminal surface with a dry, antistatic cloth. Ensure proper grounding of the terminal and surrounding equipment to minimize ESD risk. Avoid placing the terminal near sources of electromagnetic interference (e.g., microwave ovens, radios). Implement cable strain relief measures to prevent damage to the power and communication cables.
Try clearing the terminal's transaction log. Sometimes a full transaction log can cause performance issues with contactless payments. This can usually be found in the terminal's settings menu under 'Maintenance' or 'Reports'.
