| With the development of intelligent mobile communication terminal technology, various levels of governments all over the country are increasingly concerned about the smart city business, and near field radio frequency communication technology carrier by mobile intelligent terminal and people ’s life is increasingly closed. Accompanied by the pace of life accelerates, the NFC near field wireless radio frequency communication technology based on mobile intelligent terminal has become an indispensable part of the smart city.Near field communication or NFC is a sort of short-range high frequency wireless communication technology, works on 13.56 MHz band, can achieve the function of electronic identity or data transmission in short distance.Won the favor of telecom operators of all the solutions of NFC near field wireless radio frequency communication is the NFC solution of the card number and password encryption is stored in the SWP card UIM card(hereinafter referred to as SWP-UIM card), has the features of low cost, wide range of commercial, good technical compatibility and so on. This system is designed to enhance the ability of operators’ value-added services, to provide the convenience for passengers, improve city features.The system takes the mobile phone terminal as the carrier, download the bus card, bank card, access card and other smart card to the SWP-UIM mobile phone card through the provincial TSM trusted service management platform. System packaged public transportation company issuing system, charging system,user Management System in a standardized interface, and TSM aggregation distribution platform provided by communication operators can integrate bus card application, earmark, billing function, bank card wallet accounts and other smart card module.One users side, after opening the corresponding online account, loading the offline wallet into the 13.56 M mobile SWP-UIM card with RFID function and charging the wallet account, in the corresponding business alliance users can use that offline wallet pay POS multifunctional sales terminal on the site.In the process of mobile offline electronic wallet products payment, instead of interactions between POS machines and background system, payment is completed only by interactions between user RF SWP-UIM card and POS multifunctional sales terminal. In order to achieve the business functions, build smart City-Bus NFC mobile payment system key is by City-Bus, the communication business operators system external interface for docking, and in accordance with the business needs to be realized. In the project implementation process, the mobile client plans to use Javascript to carry out the development of the script. In the docking interface, reference bus card management system architecture program using XML language(Extensible Markup Language) development of the interface work load. City-Bus card system database structure will use SQL for all kinds of table structure, called query, write interface referred to in database.This paper started from the docking of Yinchuan Ningxia public transport management system and China Telecom Ningxia company TSM platform, analyzed existing business processes and requirements, demonstrated the NFC mobile payment technology to carry the smart city public transportation applications. According to application of NFC wireless communication technology to mobile payment products as terminal services and opening up the NFC-TSM model of a variety of people’s livelihood applications as a product form, citizens can flexibly download application they selected according to their needs. At last, achieve the goals of using NFC technology as the carrier of the smart public transportation mobile phone payment applications, provide theoretical basis of China Telecom Ningxia smart city mobile phone payment products finalized and on-line... |
