Remote payment technical solution

Remote payment technical solution

Remote payment refers to the payment method in which a user and a merchant do not need to interact face-to-face, but use a mobile terminal to interact with the backend server through a wireless communication network, and the server end completes transaction processing.

Based on the technology used, the remote payment technical solution mainly includes four technical solutions: SMS payment, client (no card) payment, smart card payment, and smart terminal peripheral payment.

◎ SMS payment: refers to the payment service completed by users by editing and sending text messages.

Client (no-card) payment: refers to the service for users to complete payment through the interaction between the Internet and the payment platform through a mobile Internet browser or client.

◎ Smart card payment: a remote payment service that performs security authentication by using a smart card that stores payment data. The smart card in this chapter refers to the integrated circuit card that integrates secure computing units and secure storage, including SIM/uimcard, SD card, and mobile phone built-in se.

◎ Mobile terminal peripheral payment: refers to the payment by swiping the card through external devices of the mobile terminal.

SMS Payment Technology 1. Implementation Solution

In the text message payment transaction process, the text message instruction containing the payment information is sent from the user's mobile terminal (generally a mobile phone) to the text message processing platform. After identification, review, and exchange, the payment information is forwarded to the mobile payment access platform and the Account Management System to complete related services.

The technical architecture of SMS payment is very simple. The SMS processing platform interacts with the mobile payment access platform to complete payment processing, as shown in Figure 11-1. The text message processing platform is established and managed by mobile operators and forwards messages between mobile terminals and mobile payment access platforms in the agreed format. To ensure the security of SMS payment, the transmission of SMS should adopt a robust communication transmission protocol to ensure the transmission reliability. Moreover, the account, password, and other sensitive data cannot appear simultaneously in a text message.

 

2. Technical Features

The Short Message payment solution is simple, convenient, and easy to use. In addition, the existing mobile phone and communication network environments can be implemented without any transformation, and the Business implementation cost is low. However, the SMS payment solution does not provide a good user interaction experience and cannot ensure reliable transmission of SMS messages. Therefore, it is difficult to carry the payment services that require complex interaction.

The entire process is completed online without the participation of other on-site acceptance terminals. The application system architecture of client payment is 11-3.
