How to be money smart when traveling overseas
(1) Do not carry lots of Cash
You do need to have cash on you when you are traveling overseas, there are lots of places that do not accept credit cards. You are thinking so how would I get cash to cover my entire holiday. $100 in my pocket will only cover first 2 days.
(2) Get a Travel Money Card or a Travel Bank Card.
I use Cash passport card, Which is amazing. I load it with money in the currency I need and off I go. Cash free. This card is my best friend when I am traveling. You can now get Travel Money card from a bank or Travelex.
