for the past 1 week started using rfid, below are the results on 2 cars:

car 1

grand saga batu 11 - failed
SILK sg long - failed
SILK bkt kajang - passed
LDP sunway - failed
besraya mines - passed

car 2 so far no issue. what i noticed is the sticker placement on windscreen on car 1 is higher than car 2..not sure if this determined the failed outcome..already reported to TnG and still waiting for their response

yup..

Anyone here used rfid on BKE highway (butterworth - kulim expressway). The put rfid signboard there, but when I went through at normal speed, nothing happens. I had to reverse the car and use tng card. Tried both way. It's like they put the signboard, but never install the rfid reader..

Yeah unfortunately they are different - PLUS's claim in future can directly link to bank cards, while TnG's is linked to its own ewallet.

If not mistaken, gov directive is that in future one car can only own one RFID - so we can't have both PLUS and TnG RFID on the same car...
