Diagnosing VEP RFID Read Errors at the Gantry: Is It Your Tag, the Reader, or Sunscreen Film Interference?

• Faulty or Damaged RFID Tag: Over time, heat, moisture, or physical damage can weaken your RFID tag. Even a small scratch can affect its readability.
• Gantry Reader Calibration Issues: Sometimes, the problem isn’t on your end. A misaligned or poorly calibrated gantry reader might fail to detect even a perfectly fine tag.
• Sunscreen or Tinted Film Interference: High-metallic content in some tints can block RFID signals. If your tag is placed behind such a film, detection becomes inconsistent.

• Test at Multiple Gantries: If the error only happens at one specific location, the gantry reader may be at fault.
• Visual Inspection of Your Tag: Look for peeling edges, scratches, or dirt on the surface. Clean it gently if needed.
• Check Your Tint or Film: If your tint is metallic, consider relocating the tag to an untinted section of the windshield.
• Try a Temporary Relocation: Move your tag to a different spot and test again.

Quick Fixes You Can Try

• Clean the windshield where the tag is placed.
• Reposition the tag according to JPJ’s recommended placement.
• Avoid placing the tag behind high-metallic window tints.
