Sadly hope, we use LTA introduced method call CEPAS that also uses NFC as well, if transport need to work with Apple Pay and Samsung Pay, LTA and those transport companies need to update their system, if banks introduce NFC on ATM, we can even withdraw using our phone by placing on the NFC reader instead of inserting the ATM card, as proven in Korea with Samsung Pay for transport and ATM withdraw.
Technically speaking, it's is highly possible to use Apple Pay or Samsung Pay for transport if our authority update their out dated system and allow us to allow EZ-Link card into wallet.
In future, want to go out, just bring our phone that all if transport, atm withdraw plus the current retail payment all integrate together! This is what I call cashless smart nation!
There a lot of possible to NFC technology, use digital smart lock and even can use it to lock and unlock our HDB doors, no more keys, which again Korea uses it years ago. (If you watch their drama and variety show, you will know what am I talking about), Korea is insanely high tech and everything is nothing but FAST FAST FAST!
As of now, Koreans only need two things when go out: Samsung phone and T-Money Card, no need house keys too as they all use digital lock.
