An Evaluation of RFID Security Systems and their Effectiveness

Radio Frequency Identification has tremendous potential when applied to security systems. From anti-theft to physical access, the technology has been applied in numerous ways to both enhance existing systems and become the core component of brand-new ones. While not foolproof, the application of RFID in security systems is seen worldwide, and for good reason. The versatility of RFID is a key factor when considering the widespread use of the technology in various security systems. Passive and active tags provide functionalities that only increase the overall effectiveness of the technology. The ability to make both tags and readers mobile provides a flexibility that makes the technology even more popular. Cost is another major benefit when utilizing RFID for a security system. Tags can be produced for pennies on the dollar, allowing system designers to attach tags to an enormous number of objects or products. Keeping costs down not only allows for higher expansion, but a lower initial cost when installing a new system. This paper discusses the definition and history of RFID, as well as a detailed background on the technology and how it works.
