The invention provides a method for making payment based on correlation between product specific information and terminal numbers and a system for implementing the method. The method involves providing product specific information representing payment information for goods selected by a user from a web service, dispatching the product specific information for the selected goods to the user, receiving a payment request message containing the product specific information from a terminal device of the user, obtaining the product specific information from the payment request message, obtaining a terminal number associated with the terminal device of the user from a communication network, and providing the correlation information to a payment platform, wherein the terminal number represents identification information of the user and may be used by the payment platform for search for an account of the user, and the product specific information may be used by the payment platform to deduct payment from the account of the user. By obtaining terminal number from the communication network and correlating the terminal number with product specific information, the invention allows a user to perform a one-click payment, thereby simplifying payment procedures involved in web services.
