The exchange rate will mean lots of rupee bills to manage.  Bring some paperclips to keep the denominations separate. The modern rupee is subdivided into 100 Paise (singular paisa) though this division is now theoretical; as of 30 June 2011, coin denominations of less than 50 paise ceased to be legal tender. Bank notes are available in nominal values of 5, 10, 20, 50, 100, 500 and 1000 rupees

Cash is best for markets.  Leave your debit card at home, but you can bring a VISA or MC and your PIN number to use at the many ATM's  Use you credit card only at larger (air-conditioned) stores.
