Frequently Asked Questions
What is a "zero-commission" currency exchange trap? ▼
Many airport kiosks advertise "0% commission" but give you an exchange rate 8% to 15% worse than the real mid-market rate, pocketing the hidden spread.
How can I get the best foreign currency exchange rate? ▼
Use no-foreign-transaction-fee debit/credit cards or multi-currency digital accounts (like Wise or Revolut) that exchange at true mid-market rates.
