If you are travelling around the world consider supplementing your income by send stories of your travels to a travel magazine or newspaper. If you are an entertaining writer many magazines and daily papers would welcome your travel stories. They can also arrange to place your fee directly into your bank account.
Another way to get money as you travel is by writing a travel blog. You don't even need to take a laptop with you on your travels as blog posts can be done via a mobile phone; you can also take and upload pictures this way as well.
Set up your blog prior to leaving on your trip and include methods to monetize it. This means adding widgets for Google's Adsense, Amazon Books, and numerous other widgets that will pay you each time someone clicks on them. Funds from this type of monetization will go directly to your PayPal account – usually once a month.
Have fun and make money at the same time.
