Abstract

A radio frequency identification (RIFD) inlay includes an interposer that has a chip, and an antenna on an antenna substrate. The antenna substrate has a recess or hole, and the chip is at least partially in the recess or hole. By placing the chip or the interposer face down and at least partially in a recess or hole, thickness of the inlay may be reduced.
