The new IU is designed to accept both the existing NETS CashCard and CEPAS-compliant cards such as the new CEPAS-compliant ez-link card.

Motorists have a choice to use either the NETS CashCard or the CEPAS-compliant ez-link card once the cars are fitted with the dual-mode IU.

On top of the existing NETS CashCard, motorists with dual-mode IUs also have the option of using CEPAS-compliant cards for parking charges at Electronic Parking System (EPS) car parks that support the CEPAS standard from October 2009 when these EPS car parks are progressively upgraded. Details will be announced at the end of September 2009.

On top of accepting both CEPAS-complaint stored value cards and existing NETS CashCard's, the new IU also supports CEPAS-compliant cards that allow for automatic top-up if the remaining stored value is below a pre-determined amount. The top-up feature may be activated at the point the card is purchased.

To easily differentiate new from old, the dual-mode unit is 34% to 50% smaller than the current IU, depending on the vehicle class.

Car owners are not required to change their current IU to the dual-mode IU. Nevertheless, motorists who wish to change to the new IU may do so at LTA Authorised Inspection Centres at a cost of $150 (before GST and inclusive of installation). Motorists are advised to call the Centres beforehand to make an appointment.

Since the introduction of the dual-mode IU last year, more than 17,300 vehicles have been fitted with the new IU. This comprises 14,900 motorcycles from September 2008 and 2,400 taxis/other vehicles from March 2009.
