You can use your card to make card payments in INR, however, you cannot hold this currency in the app.
This would mean that INR is not on the list of currencies that you can choose for in-app exchange, and it is not possible to store INR on a separate INR currency account.
When you make card payments in INR, the exchange happens dynamically at the moment of purchase. We won’t send INR to the merchant, instead we’ll convert your payment to the settlement currency, which is usually USD. We'll use the best rate available to you, according to our terms and conditions.
Apart from that, there might be currency conversion fees, applied by the schemes (visa/MasterCard).
