Disclosed is a method of gathering data from a hybrid RFID chip to determine usage of an item or article of clothing using a mobile device like a phone, laptop, or tablet. The hybrid RFID chip consists of a processor, a memory, a radio transceiver, a power harvesting antenna, and an impedance circuit that converts ambient radio frequency (RF) energy to electrical energy. The RFID chip receives a first power level from ambient RF energy and periodically broadcasts an identity. The mobile device can receive the broadcast identity, store the identity, transmit the identity and location to a remote server, and receive a notification message from the remote server. The remote serve can determine usage of the item or article of clothing by comparing current records to previous records of RFID chip identity, location, and mobile device application identity.

An RFID tag includes a circuit board and a plurality of functional modules. The circuit board has an antenna conductor and a ground plane. On the circuit board, a control circuit and an RFID IC are mounted. The functional modules are connected to the circuit board. The circuit board includes a main part and an extended part. The main part includes a mounting plane for the control circuit and the ground plane. The extended part includes the antenna conductor and is integrated with the main part. The extended part and the antenna conductor are longer than one edge of the main part and disposed along the one edge.

A tracking and monitoring system that uses “smart” tracking labels with printed label information on the top and electronics and sensors embedded in thin, flexible layers underneath. Labels may be used to track the location of items, and to monitor item parameters such as temperature, shock, weight, or tampering. Tracking labels may have communications interfaces to transmit label location and sensor data to a centralized server for monitoring and analysis; interfaces may include for example Bluetooth, Wi-Fi, cellular, or Amazon Sidewalk. Label location may be determined from an integrated GPS, by triangulation using received signals from cellular or other networks, or from the location of nearby connected devices. Labels may be battery powered and may use energy harvesting to obtain power from the environment. To conserve battery life, manufactured labels may be put into a hibernation state, and activated when they are placed on an item.

The appliance may also include a receiver for receiving transmission of each unique tag ID. The appliance may also include a communicator for outputting indications of identities of electronically tagged products retained in the cavity.

A system for identifying and providing for the retrieval of information relating to an individual by a plurality of authorized users comprising: a skin wearable, waterproof, non-transferable frangible individual identification device comprising an adhesive and an ink arranged on a substrate to provide a physiologically perceptible, humanly understandable information related to said individual, and a machine-readable two-dimensional code, wherein said code can be scanned for identification, interaction, information exchange, and instructions and further comprising an electronic device with the ability to send, receive, and store information; wherein once applied to skin of the individual said identification device is not removable in one piece rendering the identification device inoperable within said system once removed from skin; wherein the ink, substrate, and adhesive are biocompatible; a plurality of receivers; a computer interface device receiving information from said individual identification device and from said receivers respecting the individual identified by said individual identification device; a computer system coupled to said computer interface device, said computer system including a memory with an algorithm for processing information collected by said computer system; and a separate set of receivers and a separate service rendering system, each output information from their respective receivers to a common database, the contents of said common database being coupled to a computing device which communicates information to and from a central server. The identification device is encoded with machine-readable identification information and/or other information and may comprise optionally a Noncontact communication device such as RFID or Bluetooth circuit. A plurality of reader devices and said individual identification device provide information respecting the individual or thing identified by the inventive system.

A hybrid document includes a flexible document having visible markings. One or more light-controlling elements and a controller are embedded in or on the flexible document. The controller is electrically connected to the one or more light-controlling elements to control the one or more light-controlling elements. A power input connection is electrically connected to the controller, or one or more light-controlling elements, or both. A power source can be connected to the power input connection, for example a piezoelectric or photovoltaic power source. In response to applied power, the controller causes the one or more light-controlling elements to emit light. In some embodiments, the controller includes a memory and a value can be stored in the memory and displayed by the light-controlling element(s). In some embodiments, the value can be assigned or varied by a hybrid currency teller machine.
