A bank draft marked "cash" is equivalent to a large sum of cash. That is to say, if you have a bank draft with the word "cash" in your wallet, you can buy a coat of 1000 yuan in a big shopping mall, and just give the ticket to others directly when you pay. This is an inspection.

Bank draft payer means that company A buys materials from company B and makes company B pay the freight temporarily, so company B is the agent payer.

In the above two cases, if the ticket is lost, the payer, that is, the person or unit that gave the ticket to the owner, or the agent payer can report the loss to the bank.
