• This was done through the use of hundis, a paper document promising payment of money after a fixed period of time at a discount and certain place.
• The hundis often included insurance which was charged at different rates on the basis of value of the goods, destination, means of transport (land, river, or sea), etc.
• The sarrafs (shroffs) who specialized in changing money, also specialized in dealing with hundis.
