The Application And Development Of Micropayment In Electronic Commerce

The change of the existent way of the Internet enterprise makes the Micropayment become a hot topic. Micropayment belongs to Net payment that is different from classic payment. The characters of the Micropayment are low-value, high frequency and rapid. Those characters require a special payment solution.There are many schemes to solve the Micropayment in relative literature, such as Millicent, Payword. They emphasized the application and improvement of the protocol, but I think that it is unilateralism and half-baked. Muller developed a new valuation to value the Micropayment systems that contains three aspects, technical, social and economic. In this paper, I try to study this in economic aspect.On the basis of Information Economics, I analyze the economic characters of the Micropayment, such as the external characters, locked effect. In the forth chapter, we conclude that three factors are the key points which influence the development of the Micropayment. That is the cost of the payment, user base and the credit control of the payment procedure. In the cost aspect, the influence from cost is analyzed by the structure of it. In the user base aspect, we study the influence from the quantity of the system user on the development of the Micropayment. On the credit aspect, we analyze the influence on the user selection under the lack of credit guarantee mechanism.In practice, there are three solutions of the Micropayment mechanism that is Net-bank scheme, Mobile payment scheme and the Third-part online payment scheme. In the fifth chapter we summarize the trade flow and trade characters of the Net-bank scheme. It possesses of the trait of real time payment, non-dissension solutions, high-security and high commission charge. Those restrict it extensive use in Micropayment.In the Mobile payment scheme, it can utilize mobile telephone to pay at any time and any where. The characters of the scheme are low-efficiency, low-commission charge and low-security. The payment flow design separates payment process and clear process, it combines many Micropayments into one Macropayment and clear it through the bank, that reduces the cost of pre payment and upgrades the efficiency of per Micropayment. The Mobile payment scheme provides the most abundant user resource. On the credit aspect, it does not provide any plan to solution credit dilemma.The Third-party payment scheme provides payment service to two trade participators. They first need to establish a payment account on the Third-party payment system, consumer transfer some money to the account from bank to buy low value commodity, merchant transfer money from the account on Third-party to the account in bank when they account number accumulate to a big amount. The characters of this scheme are high efficiency and well credit guarantee. The advantage of the scheme is reducing the commission charge and giving credit guarantee. The disadvantage of it is that different Third-party payment is not current. This limit restricts the scope of application.In the sixth chapter the three type Micropayment scheme are compared in three factors which are cost, user base and credit solution. A new solution is proposed to solve Micropayment. On the base of Three-party, the new scheme brings in a clear centre to reduce the commission charge and increasing use scope.
