When traveling for leisure or business, travelers come home with unspent cash: leftover foreign currency/change from the visited places. This money is then forgotten in jars or drawers. We have solved the problem. If you are in contact with travelers (taxi drivers, coffee shops, working at airport, doing business with tourists and foreigners) you can use DropKoins mobile application to make extra money.
