Most banks offer foreign currency accounts but Maybank, CIMB etc you can only use your account to either send / receive TT payments or transfer to / from your RM account.

You won't have a card for foreign withdrawals, and can't withdraw / deposit cash.

Citibank does offer withdrawals in foreign currencies overseas and over the counter with a charge (can't recall what those charges are) and you have minimum balance requirements too.

If Amazon pays out in USD/GBP then most foreign currency accounts are about the same.

If you can deposit more (say RM150k+) you can open in Uk also which can give you debit cards too - depends what features you need.

EFT is used in US to US based accounts I believe, not USD accounts held outside of the US

Cheque in foreign currencies I have no idea - I wouldn't accept cheques because they're a pain!
