DCB Niyo global debit card will not work for DCC transactions. Dynamic Currency Conversion (DCC) transactions are international transactions done at POS (point-of-sale) in foreign countries and Ecom (online ecommerce transactions) at merchant sites registered overseas which allows cardholders to pay in Indian Rupees. In such cases, customer need to select local currency of that particular country in which he’s transacting rather than selecting INR for a successful transaction.
