Not sure if anyone using the IU by LTA encountered the same problem as me. At some car parks, the cashcard system will not be able to deduct the money from the cash card. The system prompted IU error and I need to manually insert the cash card into the machine.
Perhaps it is a system compatibility issue with the new cash card reader which can take in ezlink too?
