The Design Of The Campus One Card Proposal Based On RFID-SIM Technology

RF-SIM known as a new technology of Radio Frequency Identification(RFID), whichcombine the function of RFID and cell phone, has a broad application prospect.Especially, withthe application of this technology on “One Card Solution” in the university, students andteachers will feel more convenient.RF-SIM cards based on the dual interface smart card technology are applied to the mobile,which integrate the latest RFID technology in the mobile phone SIM card. Therefore, theRF-SIM cards not only have the functionality of the mobile communication, but also completethe cell phone on-line payment, and authentication and other functions.Firstly, a simple analysis of the principle of RFID, as well as RF-SIM one card technology,international development and application of the status quo are given; An overview of thecomposition, principles, and operating status of the RF-SIM card are introduced, of which therelevant agreement and theory are discussed; The concepts and implementation of RF-SIMdistance calibration is proposed, and the design of the core hardware is introduced..RF-SIM system is analyzed and designed from the perspective of design principles andbasis. The whole system architecture, network architecture and software architecture isdescribed in detail, focusing on the design and implementation of RF-SIM card reader. Thedesign includes Microcontroller module, Radio frequency reader module, distance controlmodule, antenna and the communication interface module.Finally, based on the theory of the entire system, a kind of access control system isdesigned in the paper, where the system’s functional module and interface design are detaileddemonstrated.
