Alien Technology - ALN 9874 Tread Inlay

Powered by Alien®’s break-through Higgs™-EC UHF RFID IC and innovative “Tread” antenna design, the ALN-9874 delivers industry leading EPC Gen 2 performance and reliability for automotive tire label and high-dielectric material applications requiring extra-high sensitivity.

With its Higgs-EC core, the “Tread” delivers next generation read and write performance, yet is completely optimized for the highest volume enterprise automotive applications.

An optimized memory footprint includes a 32-bit TID, a 48-bit Unique TID for authentication and next generation serialization applications, a 128-bit EPC memory bank, 128-bits of user memory for distributed data applications, and password protected read and write support capabilities to prevent unauthorised viewing and modification of the tag’s data.

ALN-9874 inlays are World Tag compliant, enabling consistent operation across the diverse frequencies of the Americas, Europe, Middle East, Asia, and Africa.
