Introduction And Basic Concept Of Rfid
Radio-frequency identification (RFID) is an important identification system which has gained prominence in the modern world. This wireless technology can unambiguously and automatically identify products or people without line of sight. It extracts a unique identifier from the RFID tags or microelectronic tags on the object (Knezevic, Delic, & Cegnar, 2015). The RFID technology has been utilized by many organizations to track the movement of commercial products, pets, people, and corporate assets with the help of a strategically placed reader. In fact, even governments have adopted this system to monitor the movement of different groups or individuals. According to Ajami and Rajabzadeh (2013), this technology utilizes radio waves to track the individuals or goods. Interestingly, it consists of different components including an antenna, an RFID reader, and an RFID tag. Since the RFID has electromagnetic fields, it finds it easy to automatically track and identify tags on objects (Ajami & Rajabzadeh, 2013). This is because these tags have electronically stored data which can be transmitted to the interrogator or the RFID reader.
The RFID technology has successfully been used in manufacturing, healthcare, transportation, agriculture, supply chain, and services (Knezevic et al., 2015). The system should be integrated with electronic health records, hospital information systems, and clinical decision support systems to help overcome diagnosis and medical errors. The RFID technology serves three purposes including inventory management, tracking, and validation which affirm its ability to improve productivity and yield cost savings. In medicine, for instance, the RFID technology improves medical safety because it eliminates surgical sponge count protocols (Coustasse, Tomblin, & Slack, 2013). Besides, it enhances patient safety by reducing medical errors, improves diagnostic services, and increases the pharmaceutical quality services. Although this technology has proved beneficial, the companies must beware of the security risks associated with RFID including eavesdropping, profiling, inventory jamming, and denial of service attacks (Knezevic, 2015). Without a doubt, this technology is susceptible to interface with wiretaps, interceptions, forgery, and fraud. These are security threats and concerns which can never be underestimated.
