One tradition carried on in the Navy is the use of the "chit." It is a carry over from the days when Hindu traders used slips of paper called "citthi" for money, so they wouldn't have to carry heavy bags of gold and silver.
British sailors shortened the word to chit and applied it to their mess vouchers. Its most outstanding use in the Navy today is for drawing pay and a form used for requesting leave and liberty. But the term is currently applied to almost any piece of paper from a pass to an official letter requesting some privilege.
