Research And Development Of NFC Mobile Payment In Smart Watch

With the progress of computer,communication and Internet technology,mobile communication terminals have been widely used in many fields,which is related to people's work and life.The development and progress of the network have put people in higher standards and requirements for wireless communication.As an important wireless communication technology,near field communication,NFC(Near Field Communication),with its security,simplicity,low power consumption and other characteristics will become the main technology used in mobile communication terminals.In recent years,the rapid development of smart wearable devices,and as an important smart wearable devices,smart watches have received more attention and attention.Smart watch terminal with its portability and uniqueness and other characteristics,to provide a good carrier mobile payment.In the smart watch to join the NFC function,can make people anytime,anywhere,convenient and quick to complete the payment.However,there is less research on the combination of it and NFC technology.In view of the above problems,this thesis studies the development of NFC mobile payment in smart watches.The main goal is to add the NFC chip in the smart watch terminal,so that it has the card simulation function,so as to achieve mobile payment.Thus,NFC watches pay cannot do without the hardware platform,operating system,but also need to develop specialized hardware which is a platform for smart watches and NFC chip,the software is Google Android Wear operating system platform.Based on the Android source code,NFC code,chip driver to join them,and finally in the mobile terminal successfully developed and implemented the NFC payment function.This thesis introduces the research background and significance of the NFC mobile payment technology,and briefly reviews the current development of NFC technology and the existing mobile payment solutions.Then a brief introduction of the basic technology and smart watches NFC payment terminal hardware and software architecture design,detailed design of hardware for NFC module,the software for the Android system,the software architecture,NFC functions are analyzed and introduced.Finally,according to the software architecture to complete the transplantation of NFC protocol stack and application program design of Android intelligentterminal watch to pay for the NFC software support,and the smart watch terminal NFC mobile payment function verification.
