An RFID tag includes an RFID device, an output device and a controller. The RFID device includes a storage from and into which information is readable and writable from a reading/writing apparatus through wireless communication. The output device outputs information. The controller reads information for output from the storage and controls the output device. The storage includes a first region into which the information for output is written and a second region separate from the first region. The controller updates data of the second region in response to updating output of the output device.

System and methods for maintaining a supply of health-related items are provided herein. The system includes, but is not limited to, a carrier configured to contain the health-related item.

The system includes, but is not limited to, an item presence sensor coupled to the container. The system includes, but is not limited to, a sensor tag coupled to carrier and configured to be communicatively coupled with the item presence sensor. The system includes, but is not limited to, one or more data processors configured to be communicatively coupled with the item presence sensor and configured to determine whether the health-related item is present within the container based upon proximity of the sensor tag to the item presence sensor.

An article management system according to the present invention includes: an acquisition unit that acquires article identification information, which is read from a storage medium provided to an article that passed through an article arrival port and identifies the article, by using a wireless communication device provided at the article arrival port of a shop; and a registration unit that registers the article information in a storage device so that whether or not an arrival state of the article in the shop is an arrived state and whether or not a display state of the article in the shop is a not-displayed state for the article corresponding to the article identification information acquired by the acquisition unit can be extracted from the storage device storing article information in which the article identification information, the arrival state, and the display state are associated with each other.

An example operation may include one or more of: receiving, via an input/output interface, an encrypted RF signal from an RF identification device; decrypting, via a processing unit, the received encrypted RF signal to generate decrypted data; modifying, via the processing unit, the decrypted data to generate modified data; maintaining, via a memory, a cryptographic distributed ledger based on the decrypted data and the modified data; encrypting, via the processing unit, the modified data to generate encrypted data; updating, via the memory, the cryptographic distributed ledger based on the encrypted data; and transmitting, via the input/output interface, an updated encrypted RF signal, based on the encrypted data, to the RF identification device.

An item management system and a key management system are provided. The key management system comprises: a plurality of keys, each key including an RFID tag in association therewith; a plurality of key storage positions, each for storing one or more of the plurality of keys; a visual indicator associated with each of the storage positions, the visual indicator configured to indicate a status of one or more of the key storage positions; at least one RFID reader configured to read the RFID tags of the plurality of keys; and at least one processor, coupled to the at least one RFID reader, the at least one processor configured to determine the presence of at least one of the plurality of keys in an associated storage position of the plurality of key storage positions.

A container includes a surface and an electromagnetic state sensing device including one or more resonance portions printed on the surface of the container. Each resonance portion may include an assembly of 3D carbon-containing structures that convey information of a stored item by resonating at a predetermined frequency in response to an electromagnetic radiation ping received from a user device. The resonance portions may include at least a first resonance portion configured to convey product identification information of the stored item and a second resonance portion configured to convey product state information of the stored item. The first resonance portion conveys product identification information of the stored item in response to a first electromagnetic radiation ping having a first frequency, and the second resonance portion conveys product state information of the stored item in response to a second electromagnetic radiation ping having a second frequency different than the first frequency.

A card is made from rigid plastic confirming to ISO 7810 ID-Type 1 card constructed of PVC, PET, Styrene, Polypropylene, Tyvek, or other synthetic material that is 7 mil to 30 mil thick (180 to 760 microns) with both an embedded High Frequency (HF) RFID chip and a Ultra High Frequency (UHF) chip; each chip is affixed to its own unique antenna that is appropriately tuned to operate in its designated frequency range in a passive manner such that the antenna are not physically connected to a power source such as a battery; the HF chip is encoded using NFC Data Exchange Format (NDEF) with code that directs a NFC enabled smartphone, tablet, or similar device to a dedicated website or app where it initializes the interaction by delivering in the NFC encode string identification data unique to that card's UHF RFID chip; the NFC encode string may include such data as the UHF chip's Tag Identification Number (TID), a serial number assigned to the tag that is encoded into the UHF chip's EPC memory; the delivery of the unique identifying information from the card's UHF chip allows the website or app to associate the tag with the passenger's itinerary by associating it with a ticket number, reservation number, frequent traveler number, or other identification element that is unique to the specific passenger for whom the tag is associated; wherein once the card's NFC is used to link the tag to the reservation the bag can be tracked through the transport carrier's baggage handling system using the card's embedded UHF RFID capability.

A food monitoring assembly includes at least one color sensor (36) for measuring a color of a food product (30). A RFID tag reader (42) is configured to identify a RFID tag (40) in the vicinity of the RFID tag reader. A controller (50) is in electrical communication with the color sensor (36) and the RFID tag reader (42) and is configured to identify a type of the food product and determine if the color of the food product is within a predetermined color range. A communicator (58) is in electrical communication with the controller (50) for communication with a remote location.

A method includes receiving, at a controller, a signal from each load cell of a plurality of load cells coupled to an aircraft cargo roller panel of an aircraft. Each signal is indicative of a load experienced by the load cell when cargo is on the aircraft cargo roller panel. The method also includes determining, based on the signals, a weight of the cargo, a center of gravity of the cargo, or both.

A system is provided that includes a rack including mount positions to accept electronic equipment modules that are rack mountable and equipped with respective RFID tags, and a RFID reader array including RFID readers each of which is associated with a respective mount position, and has a read field that among the mount positions extends into only the respective mount position. Processing circuitry causes an RFID reader to radiate an interrogation signal within its read field, and in response, receive module identifiable information from an RFID tag of an electronic equipment module mounted at the mount position. A signal including the module identifiable information and mount position identifiable information is transmitted to the processing circuitry, and a second signal to a computer configured to identify the electronic equipment module from the module identifiable information, and locate the electronic equipment module at the mount position from the mount position identifiable information.
