NCERT: "Pre-colonial India had well-organised manufacturing centres as well as indigenous merchant groups, trading networks, and banking systems that enabled trade to take place within India, and between India and the rest of the world. These traditional trading communities or castes had their own systems of banking and credit. For instance, an important instrument of exchange and credit was the hundi, or bill of exchange (like a credit note), which allowed merchants to engage in long-distance trade. Because trade took place primarily within the caste and kinship networks of these communities, a merchant in one part of the country could issue a hundi that would be honoured by a merchant in another place."
