A good supply of the Indian rupee (₹) INR in different denominations, some American Express traveler’s checks, and a major credit card (like Visa, MasterCard and AmEx) will be the most convenient ways to pay for products, services and experiences in the Andaman Islands. There are official money changers and banks at the airport, and you will get a better rate on the mainland than in the islands. Hold on to all your documentation during your vacation, including ATM receipts, so you can easily change your remaining rupees back to your own currency at the airport before leaving for home.
