Alien Doc RFID White Wet Inlay (ALN-9841, Higgs-EC)

Designed for stacked and dense packed documents, folders, or other paper goods, Alien Doc RFID White Wet Inlays offer superior performance and reliability for tagging of papers, files, documents, folders or other thin and tightly compact wood/organic materials. Equipped with the Higgs-EC UHF RFID IC based "Doc" antenna design, ALN-9841 inlays offer an enhanced memory footprint that includes a 48-bit Unique TID for authentication and serialization applications and password protected read and write support to prevent unauthorized viewing and modification of the tag’s data. ALN-9841 inlays deliver rapid programming of serialized tags as well as excellent read/write performance. ALN-9841 inlays are World Tag compliant, enabling consistent operation across the diverse frequencies of the Americas, Europe, Middle East, Asia, and Africa.
