It seems that almost every behavior of daily life can derive a new kind of lifestyle after combined with Mobile Internet in the period of Mobile Internet. Actually, mobile payment is a classical application of this kind of combination. When it comes to thecarrier of mobile payment, people always think of mobile phone. And Android is the most widely used mobile operation system which is known to us all. In order to support NFC,Google updated Android OS v2.3.That means the mobile phone whitch has NFC Module can use its function by installing Android OS. And with the following released version of Android OS such as Android v4.0 or Android v4.3,NFC was better supported. By the combination of Android OS and Mobile Internet, mobile payment has deeply rooted in people’s daily life.At the same time, the financial card carried IC chip gets closer with mobile phone,whitch seemed had nothing to do with financial card years ago, dule to this kind of technology. And it also changes the way of consumption of people.By the increasing of the rate of mobile payment, financial card with IC chipset has began to intergrate into people’s daily life. In the end of 2012, China published the latest version of standards of standard financial IC card v3.0, which is also called PBOC 3.0. The publishing of this rule has given a big boost to the development and the populization of financial ic card in China. And People’s Bank of China also desided to populize this kind of card before the end of 2015. It can be predicted that mobile payment will shine brightly in the area of financial IC card.This article designed and developed a set of financial load system working on the Android platform, based on the business of electronic cash loading and the research of NFC and Android. This article also described the current state of NFC techinc and its future.And it also anylised the key technology such as the initialization of NFC Service,the intent delivering,the analysis of data,respectively from the framework layer and the application layer. And the articledesigned the main frame of the server.The server of this system is constructed with the open source frame which called SSH,and I devide the server into four parts,the eneity layer,the DAO layer,the service layer and the control layer. And it also defined the frame of client, by introducing the modules such as Activity and intent.In order to construct the client, the article also designed a set of user interfaces and the way of transportation of data. After the anylisation of the actural business of electronic cash loading, a set of document was constructed referring to software engineering.The final test proved that this financial load system can be used.And according to the performance and safety,this system totally match the original design. |
