One of the key concerns facing Indian travellers is forex and the currency conversion charges. A pre-paid card, which locks the currency conversion rate for the currency loaded, will attract charges if you are using it for a currency that is not loaded in the card. Thomas Cook India, in collaboration with Mastercard Worldwide, has launched the One Currency Prepaid Travel Card to allow travellers to pay in local currencies and yet avoid paying currency conversion charges.  The card caters to 275 countries, will be accepted at 35.2 million merchants and can be used to access 2.2 million ATMs worldwide ($4/transaction charge for ATM transactions). The card has USD loaded and is valid up to 5 years. https://www.thomascook.in/.
