The local currency in Goa is the Indian Rupee (INR). It is advisable to carry a mix of cash and card. Exchange rates can vary, so it's best to compare rates at multiple forex vendors. ATMs are readily available in urban areas, but may be less common in remote locations. Credit cards are accepted at many establishments, especially in tourist areas, but it's still recommended to have some cash on hand. While mobile payment options like Google Pay and Paytm are becoming increasingly popular, they may not be accepted everywhere, so having cash or card is important.
