1. A method of manufacturing an asset tag, comprising:
- molding resin in a die to form a tag that has a body and defines a slot that opens to the outside of the tag body;
curing the resin tag;
rifling at least a portion of the surface of the slot;
placing an RFID transceiver in the slot, wherein when the RFID transceiver receives a stimulus signal, it sends an answer signal encoding data associated with a unique identifier;
injecting an adhesive material in the slot to cover the RFID transceiver; and
attaching the asset tag to an industrial asset and the answer signal includes a serial number of the asset.

Abstract
Plastic asset identification tags are described. The tags define an attachment feature by which the tag is attached to the asset. The tag also defines a cavity or slot in which an RFID transceiver is placed. Epoxy fills the remainder of the slot or cavity. The RFID transceiver is programmed to respond to interrogation by transmitting a unique identifier that is associated with the object to which the tag is attached. Additional information about the object may also be responsively transmitted, and in some embodiments that additional information is also written on the outside of the tag. Other tags seal the RFID transceiver within a pocket of flexible fabric-supported PVC.

6. An industrial asset tag for attachment to an industrial asset, comprising:
-
a plastic tag body defining a cavity and a pass-through hole, the body being constructed of a plastic material and having an outer surface and being adapted and configured for attachment to the industrial asset; an RFID transceiver in the cavity, the RFID transceiver not being exposed along the outer surface; and an adhesive material filling substantially all of the portion of the cavity not occupied by the RFID transceiver; wherein when the RFID transceiver receives a stimulus signal, it sends an answer signal encoding data associated with a unique identifier, said tag body including an asset identifier visibly and legibly placed on the outside of the tag, the answer signal encoding at least some of the asset identifier, wherein the asset identifier includes data about the asset. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. An industrial asset tag, comprising:
-
a plastic tag body defining a cavity and a pair of spaced apart pass-through holes adapted and configured for attaching said tag body to the industrial asset, the body being constructed of a plastic material and having an outer surface, the cavity not being located between the pass-through holes, said tag body including an asset identifier visibly and legibly placed on the outer surface of the tag, wherein the asset identifier includes data about the asset; an RFID chip in the cavity, the RFID chip not being exposed along the outer surface; and an adhesive material in the cavity and adhering the RFID chip to the tag body; wherein said RFID chip transmits an answer signal that encodes a unique identifier associated with the asset after receipt of a stimulus signal. - View Dependent Claims (17, 18, 19, 20, 21, 23)
