RFID tags gaining popularity in retail and manufacturing industries
Radio frequency identification (RFID) technology has been around for decades but its use has expanded significantly in the United States in recent years. More companies are implementing RFID systems to track goods and assets throughout the supply chain with the goal of boosting efficiency and reducing costs.
How RFID Works
RFID uses radio waves to automatically identify objects. An U.S. RFID Tags is attached to or incorporated into a product. The tag contains an antenna and a microchip that can be read by an RFID reader from several feet away. No line of sight is required and tags can even be read through packaging materials. When triggered by a reader's radio signal, the tag transmits a unique product number, serial number or other identifying information back to the reader.
Adoption in Retail
Among the earliest adopters of RFID were large retailers looking for more effective ways to manage inventory. Having real-time visibility into stock levels across stores helps retailers reduce out-of-stock situations while also avoiding overstocking. Major retail chains including Walmart began mandating RFID tagging of pallets and cases of goods in the mid-2000s. Smaller retailers have since followed as the costs of RFID tags continued to decline. RFID is now used widely for replenishment and locating items within stores. Some retailers are tagging individual clothing items or other merchandise to allow for new in-store experiences like touchless checkouts.
Applications in Manufacturing
Manufacturers were initially slower than retailers to invest in RFID due to the perceived costs and technical challenges. However, its use has expanded significantly in industrial environments where asset tracking, quality control and parts traceability are priorities. Automotive manufacturers in particular have driven much of the growth as they adopt RFID to meet strict supplier requirements. Electronics, aerospace, pharmaceutical and other precision industries also see value in RFID to improve operations. Common industrial applications today include component tracking through assembly lines, monitoring tool and equipment locations, authenticating parts and managing returns and repairs. Some manufacturers are now tagging individual units for life-cycle traceability from component sourcing all the way through to end of life.
Logistics and Shipping Benefits
Transport and logistics companies have also increased their use of RFID tagging in recent years. Major shippers including UPS and FedEx use RFID to automatically scan pallets and containers with active or passive tags attached. This real-time tracking allows for better routing, security monitoring and fewer manual scans by employees which can speed up the shipping process. Bulk transport of goods including raw materials often uses passive RFID which does not require a battery and can be read from great distances. RFID is also finding applications at ports where containers are tagged for automated clearance through customs checks. The technology offers a more robust way to monitor cargo shipments compared to traditional barcodes scanners which require line of sight.
Secure Access and Beyond
RFID has expanded beyond supply chain uses in certain markets as well. Hospitals leverage RFID badges to securely grant access to specific areas as well as track patient information and assets like equipment. Many universities and businesses now use contactless ID cards with embedded RFID chips for convenient access to buildings and secured areas. Zoos, parks and other large venues employ passive RFID tags for tracking animal populations. The automotive industry explores uses like passive keyless entry systems. Looking ahead, RFID continues gaining ground in applications that require automated identification from a distance, with the potential to transform operations across many sectors in the coming decade.
Privacy Advocates Voice Concerns
While undoubtedly providing benefits, RFID technologies do raise some privacy issues that require close monitoring. Critics worry that tags could potentially be read without consent to track locations or get unauthorized access to encoded information. Consumers in particular have expressed apprehension over items in their possession being remotely scanned. In response, retailers and manufacturers assure that tags are designed to only provide basic identification data rather than detailed consumer profiles. Governments have also started regulating certain applications of RFID. Overall though, as the technology matures with built-in security and privacy features, its use will likely continue widespread acceptance in business applications across the US.
