I looked around and it looks like you should be able to use it alright, there is a charge some where in the area of
2% of the withdrawl amount and 1.75% of the exchange rate of the currency you are trying to get.
What kinda switch card is it?? What company?? Look on the back of the card, there should be symbols telling you what ATM's you can use you card on. And a customer service number should be there so you can get "official" confirmation.
You will prob not be able to use it in the shops though, just the ATM's.
