I have installed rfid and resident area having rfid boom gate. Both are working fine.

I think currently, rfid is only present at toll booth where you only need to pay once. Thus, there is no entry / exit point.

Tngsb is still working with major highway operators to implement rfid with entry and exit points such as PLUS highway. Last I heard, it should be available by this year but probably the pandemic may have delayed the implementation.

A lot of people aren't aware that you need to keep the RFID strip clean. Dust and grim will reduce the scanning performance of RFID strip. I know there are user who don't wash their car for months!

Cleaning / washing it once a week will improve its performance and less likely will get stuck.
