RFID applications are commonly found in the world around us. As we mentioned before, Hi-Pass uses the technology to control the flow of traffic. RFID works with fast-moving objects and can pass through various materials, allowing for systems to accurately recognize your vehicle and collect highway tolls. The bus cards we use daily are also based on the RFID principle. The bus cards functions as the tag, and the sensor we tag with our cards functions as the reader, making it possible for us to pay our bus or subway fares conveniently. RFID is also present in real-time bus arrival information systems and store anti-theft systems, which are triggered if a tag is removed from the premises of a store. All these applications make our lives easy and convenient.
RFID has found its way into various industrial applications as well, making for highly efficient systems. A notable area where RFID shines is logistics management. By attaching RFID tags to products stored in logistics centers, readers can be used to check sales, receipts, releases, and inventory in real-time. Products can be traced all the way from the center to store to customer. This makes for faster processing speeds and lower management costs, vastly improving system efficiency.
Recently, RFID technology has found a new application in ‘pay-as-you-go food waste disposal’. Each household in an apartment complex only pays for processing of the food waste it throws away. A food waste collection bin equipped with an RFID reader is tagged with an RFID card issued to each household, which measures the weight of food waste discarded. This data is transmitted to a management system for individual billing based on the weight of food waste discarded by each household per month. Weight-based billing (KRW 37.5 per kg) has helped to reduce food waste, and RFID technology allows for effective system management.
We’ve explored the story of RFID, which has brought wireless radio technologies into full bloom. RFID is both streamlining our everyday lives and boosting the efficiency of various systems. Stay tuned for more Wireless Technology to Transform the World!
