Access control electronics tor wireless locks comprise one or more battery operated radios that receive access control codes. The wireless accessed locks locate the electronic components, circuits, sensors and antennas and many of the lock components away from the container being secured and closer to the operator/user. The disclosed access control electronics combine a proximity detection circuit comprising sensor pads and a capacitive sensing circuit and one or more short-range radio frequency antennas for reading RFID devices. The proximity sensor pads are in close proximity with the antennas, without the antennas interfering with the proximity sensing process, and the sensor pads to not attenuate the signals between the RFID devices and the antennas after the RFID devices are detected.

Disclosed are a method and an apparatus for acquiring inventory data, a terminal device and a computer-readable storage medium. The method comprises: receiving a request for inventory data sent by a terminal device, where electronic tag data of the target item being carried in the request for inventory data; according to the inventory data request, searching among inventory record data pre-stored in a blockchain network for target inventory data corresponding to the electronic tag data, where the target inventory data being corresponding to the target item; and sending the target inventory data to the terminal device.

Systems and methods to validate RFID counts may be provided. A business may affix temporary or permanent location tags with barcodes throughout an area to be counted, and the location tags may then be recorded. Manual counters may perform a piece count of items associated with each location tag. RFID counters may perform an RFID read of items associated with each location tag. All RFID reads may be associated with their most likely location tag. The manual piece count may be compared to the total of RFID tags assigned to each location tag. Locations may be rejected where the totals do not match. Locations rejected by the manual piece count comparison may then be barcode scanned and compared to the RFID reads for each location tag required to be barcode scanned. Resolution may be performed for locations where the barcode item counts do not match the RFID item counts.

A shield assembly includes a closing structure configured to be disposed over an opening of an enclosure. The closing structure includes an inner surface configured to face an inside of the enclosure when the closing structure is closed and a finger bracket structure mounted on the inner surface, the finger bracket structure having a bracket and one or more finger gaskets coupled to the bracket. An electromagnetic interference (EMI) shielded gasket disposed along a portion of the opening of the enclosure shields an edge of the opening of the enclosure or a radio frequency (RF) fence bracket coupled to a frame disposed around the opening of the enclosure creates a narrow path between the frame and the closing structure, the narrow path attenuating RF signals passing through the narrow path and shielding an edge of the opening of the enclosure.

A method for detecting receivers includes a step of detecting a receiver, in which step a general controller detects an adjustable receiver when a general antenna receives a secondary wave emitted by the adjustable receiver, followed by a reconfiguration step in which the general controller commands a controller of the detected adjustable receiver to switch to an interaction mode in which the impedance of the adjustable receiver is alternated between a first configuration impedance and a second configuration impedance in order to detect other receivers. The reconfiguration step is of a duration that is an order of magnitude higher than the duration of each alternation of the first and second configuration impedances.

A method is provided to determine unique identifiers. A physical item has an RFID integrated circuit (IC) having a unique identifier and a secret. The RFID IC may be configured to provide an identifier portion and a response to a previously sent challenge, where the identifier portion by itself is insufficient to completely identify the IC or item and the response is based on the challenge and the secret. Attempts are made to verify the response using a set of potential secrets determined using the identifier portion. If the response is successfully verified using a certain secret, the secret may then be used to determine one or more other identifier portions. The unique, complete identifier may then be determined from a combination of at least the identifier portions.

A method for bulk encoding of RFID tags. The method may include printing a plurality of unencoded RFID labels, coupling each of the plurality of unencoded RFID labels to each of a plurality of products, packaging like products from the plurality of products coupled with the unencoded RFID labels together in a container, scanning the container holding the products with an RFID antenna, and encoding each of the unencoded RFID labels coupled to each of the plurality of like products in a container simultaneously with identical information for each container.

A package scanning conveyance system that integrates a first two-dimensional image with at least a second two-dimensional image or a three-dimensional point clouds to calculate or estimate a package's physical properties, and/or determine if there are two or more packages in a pile. The captured imaging data is transformed by the inventive system to provide real-time feedback to a human operator to enable the operator to maintain an understanding of the system's performance. The imaging data may also be used to perform quality-checks on other parts of the package delivery and conveyance systems and document the condition of packages that have passed through the system.

A label applicator system includes a first label applicator moveably coupled to a track configured to be moved along the track and fixed at plurality of positions along the track and a second label applicator moveably coupled to the track configured to be moved along the track and fixed at plurality of positions along the track.
