SPEAKER: Another helpful app is a foreign currency conversion calculator. Picture yourself newly arrived in Macedonia with $1,000. Your life savings. If a trader offers you $30,000 dinars for these dollars, the right decision could determine whether you can afford to make it through Macedonia and on to your ultimate destination.

That sounds like a lot of dinars. Should you make this deal? The answer is no. If you accepted 30,000 dinars for your $1000, you would get only about half of what your money is worth. No immigrant could finance travel for long at this rate. Fortunately, as Rob Price, a technology reporter writes in Businessweek Insider September 9th, 2015, foreign currency conversion calculators are a popular choice, helping people to avoid getting ripped off as they cross borders and currency areas. After obtaining the right currency, another question is, where to even stay.
