This is the Ezlink card in Singapore. This is used as a topup card when travelling on bus or mrts. Loaded with extra $$ on it you can use it as payments on Singapore government's immigration center, Ministry of Manpower, and even on McDonalds and others.
Cool ha?
So my advice, DON'T EVER LEAVE HOME WITHOUT IT
or it would be soooo troublesome on your part. Trust me.
What's more, I just found out it's more expensive to pay cash on mrts/ buses than using this card.
I will say it again, it's the EZLink card!
