This is not a new question for travellers. What is the best way to handle money when travelling is covered on many websites. Here is the MONEY 101 FOR DUMMIES answer Koalas.
- When travelling outside your home country, credit and debit cards are the best way to handle your money.
- Use debit cards for cash withdrawals and credit cards for purchases.
- Find the best cards available in your home country. That means the cards that charge the lowest fees (ATM withdrawal fees) and lowest exchange loading.
Now here are a few facts that help understand the above. First, almost all banks charge you an exchange loading. PoppyG for example is wrong in thinking her cash card doesn't. They simply don't show you what they charge, it's included in the rate they use.
Banks exchange money at the Interbank Rate. What you want to know is what rate the card you have will exchange at. Generally, you can expect anything from 1-4.5% to be added to that Interbank Rate. Finding out what they will charge is well hidden in the fine print.
Pre-paid cards of any kind are to put it simply, for people who can't get normal debit and credit cards for some reason. ie. lack of credit rating or poor credit rating. They ALWAYS cost you more than a normal card.
Carrying cash, travellers cheques or pre-buying cash before leaving home will ALWAYS cost you more than using the best credit/debit cards.
In the case of Australians, the best Credit card currently (I believe) is the 28 Degrees card. No transaction fees and no exchange loading. http://www.28degreescard.com.au/
Simply put, pre-paid 'cash cards' are indeed for dummies.
