Avery Dennison launches Dual-Frequency RFID inlay

Avery Dennison has launched AD Slim DF EM4425 tag as an addition to its expanding dual-frequency (DF) range of RFID inlays

Avery Dennison has launched AD Slim DF EM4425 tag as an addition to its expanding dual-frequency (DF) range of RFID inlays, which provides combined NFC (HF) and Rain RFID (UHF) functionality for item-level tagging in a slimmed-down form factor. 

The new AD Slim DF EM4425 tag is designed for logistics, medical and industrial use cases while also offering customer engagement features.   
Based on Avery Dennison’s Dual Frequency product line, the inlay operates in both HF and UHF RFID frequency ranges.  
Dual-frequency provides shared memory functionality, which allows both UHF and HF protocols to update product information in real time. This enables all-in-one tool for inventory management and product authentication, enabling a consistent customer experience regardless of channel.   
Customers can use the inlay’s Rain RFID technology to establish a inventory and supply chain management system. The extended read ranges of UHF enable opportunities in warehouse management, tracking valuable goods and returnable transport item use cases.  
In tandem, the NFC technology, powered by Avery Dennison’s connected product cloud, can be utilized for further product information, inspection, validation, or providing end user-facing information such as user manuals, assembly instructions, CO2 footprint details and Return Merchandise Authorization (RMA) instructions.  
The combination of the AD Slim DF inlay with, can help customers combat product counterfeits and protect brand equity by enabling different stakeholders in the supply chain to authenticate products along the journey. Additionally, end-users can authenticate products post-purchase to support returns and recommerce by tapping their NFC enabled smartphones on the product with the AD Slim DF inlay.   
Max Winograd, vice president, connected products at Avery Dennison Smartrac, said: ‘AD Slim meets the needs for a wide range of medical and industrial item-level use cases. Our latest dual frequency inlays are highly cost-efficient, unlocking RFID value for inventory management applications, while enabling brands to combat counterfeits, and deliver specific consumer experiences. Powered by, companies can benefit from complete visibility of their items from source to consumer and beyond.’  
The AD Slim DF EM4425 tag has a compact form factor (74.2mm x 10.7mm/2.921in x 0.421in), which can be converted into end-application usage and is available in wet delivery format. This inlay comes with EM Microelectronic’s echo-V IC that is equipped with 2048 bits of fully shared user memory, accessible via both UHF RFID and HF frequencies, enabling the use of generally available readers (NFC-enabled smartphones) as supplements to dedicated UHF RFID or HF reader infrastructures.   
‘The AD Slim DF is an ideal option for deploying the unique benefits of our em|echo-V combined Rain RFID – NFC chips, enabling a complete integration of the end-user experience with the supply chain,’ said Pierre Muller, RFID BU leader at EM Microelectronic.  
‘We are excited about the cooperation with Avery Dennison, building on our decades-long partnership to drive market innovation.’
