What scams or misunderstandings can occur with money, currency exchange, atms and cards?

Cash remains useful, while cards and mobile payments are common at larger businesses. Compare exchange rates, decline poor dynamic currency conversion and protect cards and PINs. Common problems include unclear fares, changed destinations, unofficial agents, card conversion, invented damage and deposits without receipts. Confirm the total price and service in writing, photograph rentals and use official channels for complaints or tourist assistance. Money note: Exchange rates, ATM fees and card surcharges change. Compare the net amount, decline poor dynamic currency conversion and keep transaction receipts.
