Carrying ATM cards is the ideal thing to do in Goa. It is best advisable to carry ATM cards rather than cash as it is easy to keep while you engaged in various activities in Goa like water sports, sightseeing, adventure sports etc. Moreover, ATMs make it easy for an individual to avail cash whenever needed.
International travellers need not worry as the state has many international ATMs like HSBC, standard chartered, DBS, Citibank etc as well. Goa has ATM machines installed in every area at regular frequency, so it becomes safe to carry ATM card instead of cash in hand. You can keep withdrawing the amount as and when required.
