Supplementary information:
Payment settlement can be understood as a link in payment. Modern payment is regarded as the movement of funds, which is divided into behavior movement, information movement and fund movement, among which the information movement is payment liquidation.
The process of payment and liquidation can be regarded as "Mr. Accountant". The liquidation process is mainly to accurately "book" and "settle accounts" according to the actual transaction business. The main task is to find out who to pay, how much to pay and who to collect money from.
The liquidation process is the process of matching, transmitting, collecting and sorting out payment information data. This process is mainly completed through the system of relevant clearing institutions. Here, we can give an example. For example, if you go shopping in a shopping mall and spend 3000 yuan, you can pay with a bank credit card. After deducting the amount of your account from the bank, you send the transaction data message to the bank card clearing institution, where you record the data and send it to the acquiring bank. This process is the transmission and collection of data and information.
Liquidation refers to calculating the transaction principal and transaction cost one by one for the successful transactions recorded in the transaction log, and then summarizing the difference according to the liquidation object to form the receivable and payable amount. Here, we will continue to explain the above example. During your shopping, the bank card clearing institution will calculate and record the bill amount after recording. This process is liquidation.
Payment and settlement require very high security. Once there is a problem in one aspect of the system, it will affect many transactions and participants. Therefore, the payment and clearing system is also considered as an important financial infrastructure and the main artery of capital circulation, so the institutions involved in payment and clearing must be licensed to operate. In China, there are not only China Personnel Bank Clearing Center, but also China Online Banking, City Bank Clearing, Rural Credit Cooperatives, and many licensed third-party payment institutions, such as Tonglian Payment, the vice president of China Payment and Clearing Association.
