Transferwise

When traveling around the world you will encounter different currencies.  Credit cards can be a nice work around for this challenge, but many times you will need to transfer money abroad from one account to another.  While teaching English abroad I have needed to transfer money from my between accounts so I can continue to use my credit cards to earn bonuses.  Transferwise is the best way I have found to transfer money.  They use a fair exchange rate (you can use sites/apps like XE currency data to check for yourself) and they do not charge high fees like many other banks and organizations.  If you use this link you can even get your first transfer (up to £500) totally free!
