Abstract: The invention provides a radio frequency identification (RFID) tag particularly suitable for use as a linen or laundry tag, and methods for producing RFID tags. The RFID tag in one embodiment comprises a backing layer, a first adhesive layer overlaying the backing layer, an RFID transponder and antenna overlaying the first adhesive layer, and a second adhesive layer overlaying the RFID transponder and antenna. The layers are laminated together, hermetically sealing the RFID transponder and antenna within the RFID tag.

Abstract: A tag and a method of manufacturing a tag having an electronic device, which may be a transponder embedded in binding material, the method including applying a pre-coat of binding material to the transponder, at least partially curing the pre-coat of binding material, locating the resulting pre-coated transponder in further binding material and curing the further binding material. The method may further include applying a vacuum to the binding material and binding material, heating the binding materials and vibrating the binding materials. Apparatus for producing tags is also described and claimed. The tag has a construction which facilitates subcutaneous introduction into a target subject, such as an animal, and helps provide retention of the tag in the inserted position in the target subject.
