ERP. Why does thou not spoil?

As you know by now, I live in the city-state of Singapore. Here, we have one of the most ingenious methods for "managing" traffic density during peak periods over many areas in Singapore. In short, we pay more to drive into the businesses and main shopping districts.

Recently, my dad went through one of these "gantries" but was unsure if the fee has been successfully deducted from his cash-card. 

So this set me researching on what are the penalties for ERP-related offenses.

1) Receive a letter from LTA within two weeks to pay the ERP fee, together with an admin fee of $10.

2) However, you pay ERP fee, with the admin fee of $8 (less is good) if payment made online or AXS.
