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

If you’ve driven up to a VEP gantry only to have the barrier stay firmly shut, you know the frustration. That flashing “RFID Not Detected” message can turn a smooth journey into a stressful delay. But before you panic, it’s important to figure out where the problem lies — is it your RFID tag, the gantry reader, or even something as unexpected as your car’s sunscreen film?

At MyMechanic, we’ve helped countless drivers in Malaysia and Singapore diagnose and fix VEP RFID issues. Here’s how to get to the root of the problem quickly.

Common Causes of VEP RFID Read Errors

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.

How to Identify the Source of the Problem

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.
