problems and risks of four-party aggregate payment.

Generally speaking, aggregate payment enterprises do not hold the payment license issued by the People's Bank of China, so they are outside the supervision system, and their risks are mainly reflected in four aspects: information security, business breakthrough, fund management and agency chain risk.

(1) Information security.

after connecting a large number of small and medium-sized merchants and a large number of payment institutions, the aggregate payment enterprise collects a large number of consumer information, merchant information and payment institution information, including sensitive information related to account number, consumption and transaction information related to goods (services). Under the background of breaking away from financial supervision system, weak constraint of information security and Internet technology, aggregated payment enterprises will easily become the hardest hit areas of information leakage if they do not carry out strict internal control management, and the leaked consumer information, merchant information and payment institution information will bring opportunities for criminals to complete the information database.

In addition, if the science and technology risk management of the aggregate payment enterprise itself is weakened, it will easily lead to its own security risks, and technical loopholes such as order tampering and information eavesdropping will appear.

(2) business operation.

At present, the Internet financial ecology presents a vicious competition situation. In order to gain more profits, some aggregate payment enterprises deviate from the position of "acquiring outsourcing institutions", carry out payment and settlement business without a license, intervene in acquiring institutions in the mode of big merchants, open payment accounts in violation of regulations, or substantially engage in special merchants' qualification review, acceptance agreement signing, fund settlement, acquiring business transaction processing and other businesses, which seriously disrupts the normal market order.

(3) capital operation.

If the consumer's funds stay on the aggregate payment platform and deposit funds, the aggregate payment enterprise may use the funds in violation of regulations, such as handling the settlement funds of special merchants, and it is likely to become a "second clearing" institution ("second clearing" refers to a mode that units or individuals who have not obtained the payment business license of the People's Bank of China actually engage in payment business and capital settlement with the support of licensed acquiring institutions), or even "run away", endangering consumers and merchants.

(4) Agency chain.

there are usually two business development modes of aggregate payment: direct sales mode and agency mode. Among them, the agency mode is to outsource the acquiring business layer by layer, and the agents in the second, third and multi-level chains develop merchants. In order to rapidly expand their business and seize the market, some aggregation payment institutions expand their agency chain by rapidly developing agents. However, in the process of expanding the agency chain, some non-standard agents with potential risks are included in the agency chain, which leads to the spread of information security, business operation and capital operation in the agency chain and causes greater financial risks.
