I used the sticker and placed it inside my car windscreen. So far so good no issues. Also installed it on a Honda City eHev.

You can try it first. Put a clear plastic to secure the rfid sticker to the windscreen. Drive through a toll plaza if it works then good. However my car tint is JPJ compliant. If your car tint is darker you may have problem.

If you DIY the RFID sticker. Most likely will fail

This is why people still go to the RFID installation panel and do it. Because they have the right equipment to measure which location is the best

I dont get it why malaysia do not have alternative payment methods if the selected payment fail ... In Singapore even you fail to pay ERP charges can still pay later or even car parks provide another cashless method if it fails to detect

My housing area scanner is not ignoring the rfid tag... It caused me couldn't enter/exit the housing area...haiz
