Common RFID Placement Mistakes That Pass Initial Checks but Fail Later

If you’ve just had your RFID tag installed for Malaysia’s Vehicle Entry Permit (VEP), you might think you’re all set for smooth cross-border trips. But here’s the catch — just because your RFID passes the initial installation scan doesn’t mean it will work reliably every time.

Malaysia’s RFID system relies on radio frequency waves to communicate with your vehicle tag. If your tag is placed in a suboptimal position, environmental changes, wear and tear, or even car modifications can interfere with the signal, leading to failures.

• Installing Too Close to Metal Surfaces: Metal disrupts the signal. Tags should be on glass, away from frames or tint strips.
• Overlapping with Metallic Tinted Film: Some premium window tints contain metallic layers that block RFID signals.
• Wrong Windshield Zone: The tag must be in the designated zone. Too high, low, or far to the side can cause scanning blind spots.
• Placing on Dirty or Wet Surfaces: Dust or moisture can reduce adhesion, causing the tag to peel or misalign later.
• Installing Under Direct Sunlight Heat: Extreme heat during installation can weaken the adhesive bond.

Why It Works at First but Fails Later

• Weather Effects: Heat, humidity, and rain slowly affect adhesive and signal clarity.
• Car Wash Damage: High-pressure washing can loosen the edges of the tag.
• Micro Shifts: Even tiny movement from vibration can disrupt signal accuracy.
• System Sensitivity Changes: AI-powered toll readers may be more sensitive than installation scanners.

How MyMechanic Ensures Correct RFID Placement

• Tint Check: We test for metallic interference before placing the tag.
• Precision Positioning: Installed exactly within JPJ’s recommended scanning zone.
• Surface Prep: We clean and dry the area to maximise adhesion.
• Post-Install Testing: We simulate multiple scan angles to ensure reliability.

Final Thoughts

RFID placement might seem simple, but small mistakes can lead to big cross-border headaches. Even if your tag passes the first test, improper installation can cause failure months later.
