Travellers cards

Rule of the thumb is Money coming in is not an issue mostly.

Withdrawls from ATMs are possible but the limit of withdrawal amount maybe an issue to some. So is transferring money to an overseas account.

Most foreigners have issue with out-bound monies rather than in-bound.

There are extensive discussions on this topic.

Never heard of traveler's cards. Did a quick google search and see no benefit for me personally in owning one (have credit cards which don't charge international fees and offer rewards, debit card is pretty secure as I have to transfer money to the account online before usage otherwise it has a 0 balance, overdraft "protection" disabled).

Not sure what kind of feedback you're looking for on Citibank. I use a different U.S. bank with the same policy but it works with any ATM machine worldwide (unlimited ATM fee reimbursements).
