Design And Implementation Of Multi-functional Financial Visual Card

In recent years, with the development of the online banking and the popularity of smartphone device, bank customer need to use the function of the online banking on the smartphone. As usually, smartphone online banking transaction only rely on a random message, transaction security is difficult to guarantee. The authentication device of online banking based on the personal computer, such as USBKEY, is difficult to access on smartphone. Although some manufacturers improve the USBKEY, just like Audio-KEY and Bluetooth-KEY, it can not be popularized because either is too expensive or the compatibility is poorer.With the help of the financial IC card which has a large capacity, high security, support multiple applications, designing a multi-function financial visual card is possible. This card can integrate the function of the bank card and the authentication device. At the same time in order to retain the safety feature of "what you see is what it sign", add display screen and keyboard on the basis financial IC card. Smartphone can communicate with the contactless interface of card through the NFC interface, it will have better compatibility and save the cost of the authentication device.In this thesis, the main work of designing the multi-function financial visual card is as follows:1. Technical background analysis. First, analyze the development of bank card and online banking authentication device, as well as the possibility to integrate of these two aspects.2. Requirement analysis and overall design. Requirement analysis include the function analysis of the multi-function financial visual card, hardware and software requirement, standard requirement and safety requirement. Finish the overall design according to the requirement analysis.3. Detailed design and implementation. Include the hardware circuit, embedded software and smartphone software, security design and so on.4. Use the smartphone environment to test the multi-function financial visual card and analysis the test result.This thesis mainly analyzes the development of the financial card and online banking authentication device. To solve the question of difficult to use the authentication device on the smartphone, design the multi-function financial visual card, it will be helpful for the development of the financial card and online banking.
