The invention relates to the monitoring of products by means of active radio tags. According to the invention, packagings of products are provided with an active radio tag that detects at least one environmental condition and/or at least one packaging state, and which emits a signal at time intervals, which provides information about a unique identifier and at least one state in which the respective product is found. The signal is picked up by a receiver that extracts the unique identifier and the state information and transmits together with location information to a computer system.

A fastener accessory includes a fastener body and a sacrificial radio frequency (RF) tag. A dielectric substrate of the tag is affixed to a contact surface of the fastener body. An RF antenna trace is connected to or printed on the substrate. The antenna trace transmits an RF response signal when energized by an external RF tracking circuit. The substrate is plastically deformed by an installation force to prevent transmission of the response signal. A method for locating the fastener body within a search area includes exciting a receiver trace of the tag using an interrogation signal, frequency-modulating an interrogation frequency using an RF modulating circuit, transmitting a response signal at a response frequency via a transmitting antenna trace of the tag, and detecting the response signal using an RF tracking circuit to locate the fastener body within the search area.

A closed container includes a detection device for detecting opening of or an attempt to open the container. The detection device includes a contactless passive transponder that is configured to communicate with a reader via an antenna using a carrier signal. An integrated circuit of the transponder includes two input terminals connected to the antenna and two output terminals linked by a first electrically conductive wire having a severable part which is severed in the event of an opening of or an attempted opening of the container. A shorting circuit is configured to short-circuit a first output terminal with a first input terminal in the event of a conductive repair of the severed part which forms an electrical connection between the two output terminals.

In one aspect, the present invention features an identification tag as described herein. In a related aspect, the invention features packaging for a product that includes the identification tag and is useful in discouraging and/or detecting counterfeiting and product diversion.

A labeling set for marking a pharmaceutical vessel including a body having a peripheral surface and a removable closure includes: a three-dimensional molded attachment, a label for sticking on the outer vessel circumference to be marked, and an RFID transponder for electronic identification of the vessel and/or contents. The attachment is mountable and/or positionable on the vessel in a predefined relative position and has a circumferential wall with an outer circumferential surface which is intended as an additional labelable and/or electronically identifiable outer wall and/or outer surface and whose radius, outer circumference and/or wall course is selected in accordance with the radius, outer circumference and/or wall course of the vessel circumferential surface. The label and/or the RFID transponder sticks over and/or covers both a circumferential surface, formed in accordance with the vessel body outer circumference, and the attachment circumferential surface at least in regions and/or to secure the vessel attachment to the vessel.

Systems and methods are disclosed for RFID (radio frequency identifier) tags with transponders secured within housings without potting elements using one or more components located at edges of cavities for the housings. For certain embodiments, an RFID transponder is positioned within a cavity formed in a housing for an RFID tag, and regions at the edge of the cavity are deformed using heat treatment to secure the RFID transponder within the housing. For certain embodiments, click pins are used to secure the RFID transponder within the housing. Once secured, an adhesive is used to attach the resulting RFID tag to the surface of an object. Preferably, the adhesive fills at least a portion of the cavity surrounding the RFID transponder during this attachment process. Tamper resistant solutions are also disclosed.

An identity system for the Internet of Things (IOT) that enables users and machines to identify, authenticate and interact with products and collectibles without relying on a third-party-controlled authentication service. The system includes wireless tamperproof tags coupled to products and an open registry database where a chain of ownership of the items is able to be stored. The open registry enables public access to the item identity and data combined with item registration anonymity.

The present invention relates to a document comprising at least one RFID transponder, the RFID transponder comprising an antenna (3, 23) and an integrated circuit (4, 24) electrically coupled to the antenna (3, 23). The document comprises at least one detachable detuning element (7, 27) electrically coupled to the antenna (3, 23). The in-vention also relates to a method for manufacturing a document comprising an RFID transponder.

A system for controlling operation of a power tool. The system includes a handpiece having a power tool, a radio frequency identification (RFID) tag, and a wireless transceiver. The system also includes a power pack having an electric motor driving the power tool. The power pack also includes a wireless transceiver, an RFID reader, and non-transitory computer-readable storage media having computer-executable instructions for pairing the handpiece to the power pack. When executed by at least one processor, the computer-executable instructions cause the at least one processor to: interrogate the RFID tag with the RFID reader; receive an RFID signal from the RFID tag including identifying information for the handpiece; store the unique identifying information for the handpiece at the power pack; and, based on receipt of the unique identifying information, complete wireless pairing of the handpiece to the power pack.

A container including an RFID module is provided that includes a base, a metal film, and a slit. The base has an insulating property. The metal film is on a first main surface of the base. The slit separates the metal film into a first metal region and a second metal region. The RFID module includes an RFIC element, a filter circuit configured to transmit a current due to an electromagnetic wave at a natural resonance frequency being a communication frequency to the RFIC element, and first and second electrodes to be connected to the filter circuit. The first electrode of the RFID module and the first metal region of the metal film are electrically connected to each other. The second electrode of the RFID module and the second metal region of the metal film are electrically connected to each other.
