means A short written note that either records a small debt or acts as an authorized voucher for payment or goods — the slip of paper that says 'I owe this' or 'this is approved.'

from Traces back to Hindi chitthi, meaning letter or note, picked up by British colonists in India during the East India Company era. The British in India used chits constantly — at clubs, messes, and shops — to buy on credit and settle up later, and they carried the word home with them, where it narrowed down to this specific sense of a note promising payment.
