AD-681m4D, AD-681m4QT, and AD-681m4i inlays from Avery Dennison share a unique, dual dipole design which provides orientation insensitivity and outstanding read performance for a wide variety of UHF RFID tagging applications. The design is available in three chip formats: Monza 4D, Monza 4QT, and Monza 4i by Impinj. 

Providing high level performance in orientation-sensitive applications, AD-681m4D, AD-681m4QT, and AD-681m4i are a perfect fit for specific applications in supply chain management, asset tracking, and package tracking. 

The inlays are available with different versions of the Impinj Monza 4 chip. These chips differ in their EPC memory (128/128/256 bit) and User memory (32/512/480-bit), but share a 48-bit unique serialized TID Number. All three versions are available in Dry Inlay and Wet Inlay delivery formats.
