Ya, second time top up RM10 using AMEX only requires PIN.
Hmm If I top up few hundreds to 1K, it will paid to BOOST APP 3D-EC (with OTP), whereas below RM100, it will paid to BOOST APP SSL-EC (without OTP)

i suppose coincidentally, your 1st reload is new card to boost, so it will need OTP (3D transaction). then 2nd reload is <rm100 (card saved in boost), hence will be without OTP (non-3D aka 2D).
with the card still saved, you can try again with amount >rm100, see if you need OTP again.
rm4 is preauth amount, purposely charged to the new card. it will be "released" back without you noticing it in your cc statement.
no way.
1st time always a non-saved card lor. then the card is auto-saved into boost.
alternate way, remove the card after reload. then next time you reload, will be from "non-saved" card lor. of course you will always get the rm4 preauth charge, but no big issue for cc reload.
For me, the 1st reload on the same day right after adding the card would require OTP (not talking about the RM4 pre-auth). If I were to reload on the next day, no OTP required for the 1st reload. However, for subsequent reload on the same day, OTP was required again.
Btw, for those having problems with reloading Boost using BigPay, was OTP required? For those that managed to reload, was OTP required? Please share your experience.
