Background

This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.

At present, the main mode of online shopping by a user through a mobile phone is to select and purchase commodities through a merchant APP, and invoke an APP (or H5 page) of a third-party payment mechanism or a bank in a payment link to initiate user identity verification and payment. According to the online shopping method, when the account number and the password of the payment protocol of the third-party payment mechanism or the bank APP are stolen or cracked, the stealing event can still occur under the condition that the mobile phone of the user is not lost, and the economic loss of the user is caused. In addition, shopping and payment processes are carried out through the merchant APP, although the shopping and payment processes are generally applied to scenes that users select commodities by themselves, for shopping scenes such as air tickets, movie tickets, hotels and the like, some users hope to access through the telephone, complete commodity purchasing under manual guidance, and then complete transaction. At present, a merchant uses a telephone shopping system, but in a payment link, a user inputs information such as a card number, an expiration date, a CVV (verification code of a credit card, generally a three-digit verification code on the back of the credit card) and the like through a telephone base or a mobile phone key, and the merchant system sends the collected information to an issuing bank through an acquiring organization system to complete identity authentication and payment. This payment method has a high risk, and the merchant may acquire the user sensitive information and generate a fraudulent swipe.

Fig. 6 is a flowchart of an overall telephone payment method in the embodiment of the present invention, and as shown in fig. 6, the overall method of the present invention includes the following steps:

101) the user dials the telephone of the merchant through the fixed phone or the mobile phone, and the telephone sales terminal receives the call dial-in of the user.

102) And judging whether the user selects a manual process or an intelligent voice process. If the flow is a manual flow, step 103 is performed, and if the flow is an intelligent voice flow, step 104 is performed.

103) The telephone traffic salesman carries out voice conversation with the user, and according to the requirement of the user, the telephone traffic salesman inquires a proper commodity and carries out ordering operation. Before ordering, the user needs to input a mobile phone number or a mail address for receiving the payment link.

104) And starting an intelligent voice flow, analyzing the voice of the user to obtain the intention of the user, initiating commodity inquiry to a merchant order center server by the system according to the requirement of the user, and then performing ordering operation according to the requirement of the user. Before ordering, the user needs to input a mobile phone number or a mail address for receiving the payment link.

105) After receiving the order placing request, the merchant order center server updates the inventory quantity of the commodities according to the information such as the commodities, the quantity and the like sent by the user, and generates a merchant order.

106) The merchant order center server initiates a payment request to the acquirer server.

107) And the order receiving mechanism server generates a payment link according to the order content. And returning to the merchant order center server. And the merchant order center server sends the information to a mobile phone or a mailbox reserved by the user.

108) The user opens a short message or a mail to click on the payment link through the mobile phone, and calls up a cashier desk H5 page of the acquiring mechanism.

109) And the user selects the payment mode and calls up the signature checking platform corresponding to the payment mode. The payment modes selectable by the client comprise third party payment, face payment, fingerprint payment and the like.

110) And checking the identity of the customer through the signature checking platform, and synchronously checking whether the mobile phone number provided by the order issuing of the user is consistent with the payment mobile phone number reserved by the customer. If the verification is successful, step 112 is entered, otherwise step 111 is entered.

111) If the identity verification fails, an error is returned, and the transaction fails.

112) The acquirer server sends a payment request to the issuer server.

113) The card issuer server checks the identity of the client, checks the account status and balance, and completes payment processing.

114) After the payment is successful, the acquirer server informs the merchant of the telephone sales terminal and the user.
