Design&Research Of Smart-card Hub System Model Based On Nfc (Near Flied Communication) Tech.

With the rapid development of science and technology which include Internet tech., communication tech., information tech., and electronics tech, the function of the smart card is getting stronger and stronger, at the same time the smart card has also more and more been used in every aspect in people’s daily life, even some smart card have become necessities of people’s daily outing. The circulation of smart card is growing so rapid that it makes the kinds of smart card also as growth, together with the different criterion and development policy supported by different smart card manufacturers, which triggered a new problem:people need to carry more and more smart cards in order to meet the diverse needs of going daily outing.At the same time, nowadays with the increasing popularity of the smart devices, especially the smart-phone with NFC is in process of explosive growth, which provides a platform for integrating and managing personal smart cards by smart intelligent devices. Android OS2.3.3joins the support for NFC which brings more convenience and possibility to my research.This paper introduces the technology principle, characteristics, criteria and main application scenarios of the NFC tech. at first, then makes an analysis on the NFC’s current situation at home and abroad. So this paper put forward that we can design a "smart card hub system" based on Android and NFC, which could integrate and manage personal smart cards and solve the problem that people have to carry several cards. This "smart card hub system" also could bring people an efficiency and quality life.Furthermore, this paper gives an solution to mark non-NFC smart devices becoming NFC devices with NFC function extension suite. In this research process, we develop an Android application called "smart card hub system" based on Android OS and NFC tech. With the "smart card hub system" we make that add a smart card into smart-phone by scanning and automatically identify when using cards come true.The "smart card hub system" model achieves our pre-functions such as card-reading, information storage, information processing and card simulate, This paper has achieved expected effect.
