On my most recent international trip I visited three countries that all used different currencies. By the time I got home, I had a baggie full of miscellaneous coins and bills that may never get used. Now, all of that cash resides in the back of a drawer with coins and bills from a dozen other unused currencies.

The new TravelersBox kiosk service that’s popping up in airports around the world is just the ticket for this nearly universal travelers’ dilemma. Already available in ten international airports in seven nations, the simple,automated service allows flyers to deposit leftover coins or bills and receive iTunes credits, gift cards, store vouchers, make charitable contributions, or even direct deposit to digital accounts such as Paypal.

TravelersBox is currently available in Canada, Italy, Israel, Turkey, Japan, Georgia, and Singapore, with more sites to be added very soon.
