What is the most practical way to handle 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. Compare total cost, reliability and risk rather than choosing only by the lowest price. Keep the address in Thai and English, confirm the fare or booking in the app and allow extra time for traffic or queues. Money note: Exchange rates, ATM fees and card surcharges change. Compare the net amount, decline poor dynamic currency conversion and keep transaction receipts.
