Not sure whether this was asked before but does all Aeon card has the same conversion rate ? (visa to visa comparison)(aeon gold vs aeon watami vs aeon big). They are all under Aeon Credit right?

** Can't seem to get the Mastercard rate on 6-Feb-2016, so i take both the 5th and the 8th for reference.

Summary:
1. Seems like Aeon Big Card != Aeon Credit
2. Aeon Big Card seems like a NO-NO for overseas transaction ( with the rm25 cashback with limited pool )
