The Design Of Smartphone Card System Based On NFC

NFC(Near field communication) is a kind of close range wireless communication technologymutually compatible with existing 13.56 MHz RFID technology.It has the features of fastspeedestablishment and high security. based on the technology of combining it with mobile phones, tablet PCs, mobile intelligent terminal, the business card system application can let people effectively get real personal informationin today’s complex and changeable business environment, so as to avoid business risk.The application and development of this business card system is mainly divided into two stages.First is the research of the NFC module to read and write function and the development of the business card system.The implementation of NFC module to read and write function is connected in the NFC module and the PC terminal,based on windows system,using vs2008 to develop client controlling the operations of NFC module to read and write NXP M1 card,and also research the operation process of HAL(Hardware Abstraction Layer) during the time.And then is the Business card system. It is a simple,convenient and efficient personal information query system based on the Android system,using the eclipse as a development tool and SQLite as the database to record personal information records,combined with after certification of individual website.Through scanning with the label business card, reading the label for specific information and contrasting in the database,the system can query the appropriate information and display it.After clicking on the URL information users can enter personal website to read the details.Finally after the implementation of the entire project, PC and Android programs have experienced testing.Compared to the same type of software PN544 FRI1.1training,the PC client’s function is more simple,and due to it,the time needed in theinitialization of the software will short approximately 18.9%,and the label setup time will be about one third of it.In the android program,after a large capacity test,except the function of the label setup is 99%,the rest are 100% successful.They are all basically implementing research requirements.
