物联网技术之RFID识别

摘要

RFID是目前应用于物联网的一项新兴通信技术，可通过无线电信号识别产品电子标签内的EPC码来识别特定目标，而无需识别系统与特定目标之间建立机械或光学接触，它的应用给物联网行业带来了革命性的变化，极大地节省了管理成本，提高了管理效率。文章重点对RFID的工作原理、安全性、现状及发展趋势进行了阐述。%RFID is a new communication technology of IOT, which read EPC code in electronic tag in order to recognize the special objective through radio signal, and no need to recognize the mechanincal or optical contact between the system and special objective. The application of RFID technology bings revolutionary changes to the IOT industry, it not only saves the management cost, bust also improves the management efficiency. Finally, the paper elaborate the working principle, security, current situation and development tendency of RFID.
