The RFID tag is fixedly attached to the needle shield through co-molding or another form of permanent attachment. The present invention also relates to a method of tracking the life cycle of a medicament injection device where the RFID tag enabled needle shield assembly is attached to an injection needle that is connected to a syringe barrel that is part of an injection device. Data is written to or read from the RFID tag during the entire life cycle of the injection device, including assembly, packaging, storing, distribution and use. ## Claims ### Claim 1 A shield assembly for providing a sterile enclosure of an outlet fixedly attached to a container of medicament positioned within a medicament delivery device, the shield assembly comprising: a rigid sheath configured to fit within, be surrounded by, and operatively engaged with a grabber that is axially fixed to a protective cap connected to a proximal end of a medicament delivery device such that removal of the protective cap from the medicament delivery device causes the grabber to remove the shield assembly from the container of medicament; a flexible sheath positioned within the rigid sheath and surrounding the outlet of the container of medicament; and an RFID tag fixedly positioned between the flexible sheath and the rigid sheath and not attached to the protective cap. ### Claim 2 (depends on 1) The shield assembly of claim 1, wherein the flexible sheath has an outside surface and the rigid sheath has an inside surface, where the RFID tag is positioned between the outside surface and the inside surface. ### Claim 3 (depends on 1) The shield assembly of claim 1, wherein the flexible sheath abuts the RFID tag positioned on an inside surface of the rigid sheath. ### Claim 4 (depends on 1) The shield assembly of claim 1, wherein the RFID tag is read-write tag. ### Claim 5 (depends on 4) The shield assembly of claim 4, where the RFID tag further comprises a read-only memory that contains product identification data. ### Claim 6 (depends on 1) The shield assembly of claim 1, wherein the rigid sheath is attached to the flexible sheath such that axial movement of rigid sheath causes axial movement of the flexible sheath and the RFID tag. ### Claim 7 (depends on 1) The shield assembly of claim 1, wherein the RFID tag is fixedly attached to an inside surface of the rigid sheath. ### Claim 8 (depends on 7) The shield assembly of claim 7 wherein the RFID tag is fixedly attached by one of a snap fit, an inlay, co-molded, an adhesive, lamination, paid, a press fit or a combination thereof. ### Claim 9 (depends on 1) The shield assembly of claim 1, further comprising an antenna in electrical communication with the RFID tag. ### Claim 10 (depends on 9) The shield assembly of claim 9, wherein the antenna is positioned on an outside surface of the rigid sheath. ### Claim 11 (depends on 1) The shield assembly of claim 1, wherein the flexible sheath is permanently attached to an inside surface of the rigid sheath. ### Claim 12 (depends on 1) The shield assembly of claim 1, wherein the flexible sheath has an interior portion comprising a material that forms a sterile and fluid tight seal with the outlet of the container of medicament. ### Claim 13 (depends on 12) The shield assembly of claim 12, wherein the outlet comprises an injection needle. ### Claim 14 (depends on 1) A system comprising: the shield assembly of claim 1; and a device accessory that is configured to read data from an RFID tag.
