Abstract
A radio frequency identification (RFID) inlay includes a conductive connection electrically connecting an antenna to strap leads that are coupled to an RFID chip. The conductive connection may include conductive bumps attached to the strap, and/or may include conductive traces, such as a conductive ink traces. The conductive connections provide a convenient, fast, and effective way to operatively couple antennas and straps. The RFID inlay may be part of an RFID label or RFID tag.
