At 1st I tot MBB master /visa is the lowest bank fee I mean admin fee and forex rate charger , but look like maybe not...
I which will be lowest now...
comparing cash when you go travel I recall some time card will give you lower rate cause cc is base on the day where you posted rate.... and cash usually more early day you exchange at money change usually before your travel date.
But if goble currency let put to fix.. cash should be always lower?
Or card currency give better rate?
