How Accurate is RFID Asset Tracking Prem Arumugam Radio-frequency identification (RFID) asset tracking has been gaining popularity in recent years, especially in the field of supply chain management, inventory control, and asset management. It is a technology that uses radio waves to identify and track objects that are equipped with RFID tags or transponders. While RFID asset tracking is considered an efficient and cost-effective solution, the question remains: How accurate is RFID asset tracking? RFID accuracy depends on various factors such as the type of RFID tags, the distance between the reader and the tag, the frequency of radio waves, and the environmental conditions. Passive RFID tags, which do not have their own power source, fully rely on the energy transmitted from the reader to power them up, and therefore have a shorter range than active RFID tags that have their own power source. RFID Frequency Furthermore, the RFID frequency ranges also affects the accuracy of RFID asset tracking. Higher frequencies provide greater accuracy, but shorter range. In contrast, lower frequencies provide greater range but lower accuracy. The distance between the reader and the tag is another important factor that affects RFID accuracy. The closer the tag is to the reader, the higher the accuracy of tracking. Environmental Conditions Environmental conditions such as metal, liquid and other materials can interfere with RFID signals and reduce the accuracy of tracking. For example, RFID tracking in a warehouse with metal racks and shelves can be less accurate than in an open field due to the interference of metallic racks. RFID Scanning RFID scanning is the process of reading the chip memory of an RFID tag by energizing the tag with power from an RFID reader’s radio waves. This method differs from barcodes, where data is encoded in the dark lines and spaces of the barcode, which can be susceptible to wear and tear. In barcodes, even the erasure of a single dark line or spot due to wear and tear can alter the data value. How Accurate is RFID Despite these challenges, RFID asset tracking is generally considered highly accurate. The accuracy of RFID asset tracking can range from 99% to 99.9%, depending on the specific application and the quality of the RFID system. RFID asset tracking can significantly improve efficiency and productivity in industries such as logistics, healthcare, and manufacturing. By providing real-time tracking and inventory management, RFID asset tracking can help organizations reduce the risk of theft, loss, or damage of assets, and improve overall supply chain management. One of AssetPulse’s customers was using barcode labels for tracking their lab equipment and their calibration due dates. They found it very cumbersome, labor intensive and time-consuming to perform inventory audit as well as scan the calibration information of each equipment one by one, since barcode requires line of sight to scan. It used to take 2 months to perform inventory audit. With AssetPulse’s RFID asset tracking solution they were able to rapidly scan the RFID tags on multiple equipment and hence the inventory audit process gets completed in 1 – 2 days as opposed to 2 months with barcode earlier. In conclusion, RFID asset tracking is a highly accurate and efficient technology for asset tracking and inventory management. While there are some challenges in accuracy due to environmental factors, the technology has proven to be highly effective in improving supply chain management and inventory control. As RFID technology continues to improve, we can expect to see even greater accuracy in the future.
