The title holder has to assign the title to the payment ... somehow. Bearer instruments of course escape the requirement for endorsement. Title to a non-negotiable can be conveyed by assignment (perhaps consider the backside of stock certificate). Title to the money inuring from a negotiable instrument can be conveyed by endorsement. An endorsement can be in blank or it can be special. Similarly there are general deposits and there are special deposits.
One of the biggest change with the FRB was the obfuscation of money-related knowledge in public schools in the United States of America.
