![]() ![]() UK clothes retailer, River Island, increased their stock accuracy from 70% to 98% by deploying RFID tags across all of its stores.From manufacturing plants and school facilities to retail stores and warehouses, it’s tracking capabilities can be seen everywhere: Since its relatively new beginnings, RFID asset tracking has been deployed across multiple industries and businesses. ![]() The latter alerting all asset-heavy consumer-focused organisations to capitalise on RFID technology. Over the next 80 years, RFID technology evolved a patent for the first RFID tag was drawn up in 1973, the first Ultra-High Frequency (UHF) reader was invented by IBM in the 1990s, and by 2004 the American retail juggernaut Walmart had spent near to $500 million on its RIFD programs. In fact, the first working RFID tracking system can be traced back to the Second World War when it was used to track and identify enemy aircraft. Utilising Radio-frequency identification for the process of tracking physical ‘things’ is not a new concept. Tracking multiple assets at any one time.The ability to automate your tracking and monitoring processes aims to put an end to the highly error-prone methods of pen-and-paper and excel spreadsheets. Eventually collecting it in a sophisticated asset tracking system where the data can be monitored and actioned. Through an RFID tag’s repeatedly pulsating radio waves, an RFID reader is able to capture the stored data. This data can include anything from name, condition, amount, and location. It works by loading an RFID tag with data and attaching it to a relevant asset. In its simplest form, RFID asset tracking is a way of automating the management and locating process of physical assets. Whether that be stock, tools, IT devices, vehicles, or even employees.Īlthough there are various options available to ease the process of monitoring and tracking assets, there is one tracking technology that offers complete efficiency in the most cost-effective manner RFID. However, RSSI is simple and easy to implement but sensitive to noise and multipath effects while AOA is more accurate and robust but requires more complex and expensive hardware.As a business that relies on the availability of its high-value assets to generate revenue, you’ll understand the importance of asset tracking and effective inventory management. Using these methods, you can obtain the position of a tag by triangulating distances or intersecting directions from multiple readers. This method is more precise and stable than RSSI and AOA, but requires precise synchronization and clock calibration between tags and readers. TOA measures the time it takes for the radio signal to travel from the RFID tag to the RFID reader, and uses it to calculate the distance between them. AOA measures the angle of the radio signal received by the RFID reader from the RFID tag, and uses it to calculate the direction of the tag. RSSI measures the strength of the radio signal received by the RFID reader from the RFID tag, and uses it to calculate the distance between them. There are various methods of RFID localization, such as received signal strength indication (RSSI), angle of arrival (AOA), and time of arrival (TOA). ![]()
