Abstract

A radio frequency identification device provides a stored identification value to a radio frequency reader. The radio frequency identification device stores the identification value in a logic/memory block, and has an antenna and demodulator circuit connected to the logic/memory block. The antenna is spaced remotely from the logic/memory block, with a connector electrically coupling the antenna to the logic/memory block. In one implementation, the antenna is on an antenna member and is external to a target device, while the logic/memory block is placed inside the target. In this way, the antenna is positioned for improved RF communication. The antenna member may electrically and mechanically connect to the target through a connector, such as a custom connector, power connector, audio connector, or video connector.
