PAYMENT METHOD AND SYSTEM FOR PLEDGE-PAYABLE ONLINE TRADING

摘要

A payment method and system for pledge-payable online trading. The method comprises the steps of preparing for pledge payment capacity, prompting pledge payment capacity, executing pledge payment capacity and paying for conditional redemption at maturity. The system comprises a seller member end electronic device (1), a seller member communication device (2), a seller member end pledge-payable system (3), a buyer member end electronic device (4), a buyer member communication device (5), a buyer member end pledge-payable system (6), a pledge-payable platform (7) and a pledge-payable platform end pledge-payable system (8), wherein same are connected by means of interconnection networks, such as the Internet. Endowing a pledge-payable electronic coin with a pledge payment function and a bidirectional multilateral guarantee function overcomes defects of the unidirectional unilateral guarantees of electronic cash, cuts off the path to stealing the electronic cash and the path to consumption of stolen electronic property, prolongs the time for collecting the stolen electronic property, and maintains the online trading security and the online payment security.
