It is cost savings as no need to employ staff to man the counter. TnG is all automated. Same for paying toll when U exit from S'pore to Malaysia; last time cash accepted; then few yrs ago, must use TnG to pay toll. Just imagine how much the save... need 3 person working 8 the shift to man the counter..assume all-in expense per person is RM3,000/mth. 1 yr save RM108,000.
