Currency Information, Travellers Cheque, credit cards and Atm
Indian Currency is the Indian Rupee (Re/Rs). Since you are not allowed to bring in Indian currency, your best option is the airport bank. Indian Rupee notes are printed in denominations of Rs 1000, 500, 100, 50, 20, and 10. The Rupee is divided into 100 Paise. You will see only 1, 2, 5 Rs coins, though coins below 50 paisa are rarely seen.
You should keep small denominations notes for the small payments like tips, bus tickets, and meals. When going to a remote area or small town where encashing of travellers cheque will be difficult you can take 1000 Rs and 500 Rs notes, but you should be careful when using them and should not be confused with 100 Rs.
