Design and Implementation of Remote Visitor System Based on NFC Technology

Most visitor systems’ information management is at a low level, and the processing method is still semi-manual registration. To improve the level of automation of the visitor system, this paper designs a remote visitor system based on NFC technology deployed on the Android smart-phone platform. It reads and emulates card data through NFC technology and adopts SM series algorithm to encrypt and decrypt the transmitted data. The system effectively solves the problems about security and automation in the traditional guest system.
