People leave their names (type a financial word)

A: Demand deposit.

Demand deposits account for the largest part of a country's money supply and are also an important source of funds for commercial banks. In view of the fact that demand deposits not only have the functions of monetary payment and circulation means, but also have strong derivative ability, commercial banks must take demand deposits as the focus of their operations at any time. However, due to frequent deposit and withdrawal, complicated procedures and high cost, commercial banks in western countries generally do not pay interest, and sometimes even charge a certain handling fee.
