RBI has allowed non-residents to carry Indian currency (upto Rs 10,000) beyond immigration or customs desk to duty free area and Security Hold area (SHA) in departure hall at international airports to meet miscellaneous expenses.
However, they are barred from carrying Indian currency beyond SHA in India. They should dispose of Indian currency before boarding plane.
Foreign Exchange Counters could be set up beyond immigration\custom desk for non-resident Indians to convert unspent Indian currencies.
