The invention relates to a chip card designed to communicate data in a contactless mode with a card reader operating at a reading frequency. The resonance frequency of the chip card may change according to the capacitance of the chip used in the contactless mode of the chip card. In order to be able to use various chips without changing the booster antenna design, the card antenna circuit is provided with a capacitance element such that the chip card including the card antenna circuit and the chip module has two different resonance frequencies, one of which being equal to, or lower than, the reading frequency and the other being equal to, or greater, than the reading frequency. This create a broadband wherein the reading frequency falls.

A radio frequency identification (RFID) system includes an array of antennas to distinguish line-of-sight (LOS) paths from non-line-of-sight (NLOS) paths. The distance between adjacent antennas in the array of antennas is less than half the wavelength of the radio frequency (RF) signal of the system. Each antenna in the antenna array is also digitally controlled to change relative phase difference among the antennas, thereby allowing digital steering of the array of antennas across angles of arrival (AOAs) between 0 and π. The digital steering generates a plot of signal amplitudes as a function of AOAs. LOS paths are distinguished from NLOS paths based on the shapes (e.g., depth, gradient, etc.) of local extremes (e.g., maxima or minima) in the plot.

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.

The present invention relates to a locker and system for secured delivery of goods to consumer wherein the locker may be 1) positioned within a building or home such that one door is accessible outside the building or home and a second door is accessible within the building or home; 2) positioned on a property, potentially near a curbside and accessible to a delivery vehicle from a street; or 3) positioned at a commercial location such that one door is accessible to the public and a second door is accessible to the workers at the commercial location. Delivery may occur via drone or human with selected access given to the designated locker door. In accordance with the foregoing objects, an embodiment of the present invention generally comprises a service provider, a service client, an operator (seller or inspector), an end user (buyer or end user), and at least one chamber having at least one remotely controlled electronic door in communication with a service provider, service client, and/or operator.

Control over the operation of an electrically-controlled motor is supported by an interface circuit between the electrically-controlled motor and a near-field radio frequency communication controller. The interface circuit includes a first circuit that receives at least one control set point through a near-field radio frequency communication issued by the near-field radio frequency communication controller. A second circuit of the interface generates one or more electric signals in pulse width modulation based on the control set point.

Example embodiments of systems and methods for contactless card verification include a contactless card including a substrate, a processor, and a memory, wherein the memory contains a first applet and a second applet, and a recipient device in data communication with the contactless card, wherein the second applet is configured to retrieve one or more parameters from the first applet via an interface; and wherein the second applet is configured to transmit the one or more parameters to the recipient device for verification.

The proposed invention discloses an automatic search method for a structural mode signal of a chipless RFID tag. A reference plane, a target to be tested, a reader antenna and a reader are set in space. The target to be tested is located within the reading range of the reader antenna. The distance difference between the tag and the reference plane, to the antenna, is measured by using the phenomenon of the backscattered signals of the tag and the reference plane interfering in space, to obtain the distance between the tag and the antenna. The time period for extracting the antenna mode of the tag may maximize the use of the antenna mode signal, thereby enhancing the accuracy of reading the tag.

An identification system for automatically identifying a medical tool includes at least one tool holder or packaging having a readable data carrier and designed to hold the medical tool. The system also includes an identification device to identify the medical tool. The tool holder or packaging is designed such that removal of the medical tool automatically closes a circuit provided on the tool holder or packaging and activates an antenna. The identification device is also designed to detect activation of the antenna and to read the data carrier of the tool holder or packaging.

The present disclosure describes techniques that facilitate a Governance Regulatory Compliance (C-GRC) controller that is configured to dynamically monitor and collate data associated with an agricultural operation for demonstrating compliance with an agricultural compliance plan. The C-GRC controller may act as a centralized server that dynamically monitors the cycle of agricultural activities for an agricultural product and in doing so, automates the governance of an agricultural compliance plan across a plurality of entities that are each responsible for one or more agricultural activities. The C-GRC controller may detect independent interactions conducted between a complying entity and a participating entity. These interactions may be intended to gather information relating to compliance of a pending task. In doing so, the C-GRC controller may update an agricultural compliance plan accordingly. The C-GRC controller may dynamically advance progress through an agricultural compliance plan or dynamically regress progress based on a complying entity retracting compliance.

A transaction card may monitor an amount of electric current induced in a first near-field communication (NFC) component of a transaction card. Electric current may be induced in the first NFC component when the first NFC component is within an electromagnetic field generated by a second NFC component of a transaction terminal. The transaction card may dynamically activate one or more output components associated with the transaction card based on the amount of electric current induced in the first NFC component. The one or more output components may indicate whether the transaction card can communicate with the transaction terminal. The transaction card may perform an action related to completing a transaction after determining that the amount of electric current induced in the NFC component satisfies a first threshold. The first threshold may indicate that the transaction card can communicate with the transaction terminal.
