The Land Transport Authority (LTA) and NETS are jointly investigating the cause of ERP payment issues, following feedback from motorists.
Findings so far point to about 250-300 cases a month of ERP transactions experiencing problems of compatibility between the IU and CashCards.
From 28 May, the LTA and NETS will introduce integrated testing of NETS CashCards and In-Vehicle Units (IU) at LTA Authorised Inspection Centres.
With the new service, motorists who encounter any problem with their ERP transactions can visit any authorised centre to test both their NETS CashCard and IU.
Motorists, whose NETS CashCard or IU is found to be faulty, will get a one-for-one NETS CashCard or IU replacement, and the administrative fee waived.
