Radio frequency identification (RFID) enabled readers and systems and methods for filtering cross reads of RFID tags and use thereof. The systems and methods may be configured to operate with mobile and/or fixed RFID readers. The systems and methods may provide for claim based filtering of cross reads based upon adjusting operating powers of RFID readers and/or antenna. The systems and methods may also be configured to apply weights to claims thereby providing efficient and/or accurate filtering of cross reads. The systems and methods may also provide for a database that may also be presented to a user to illustrate locations of inventory at any point in time or over a period of time, or to facilitate the ability of a user to physically locate inventory to be acted upon.

According to an embodiment, a wireless tag communication device includes a first antenna that emits radio waves towards a first region of a conveyance path for wireless tags and a second antenna that emits radio waves towards a second region of the conveyance path on downstream of the first region along the conveyance path. A shield prevents the radio waves emitted from the first antenna from reaching a first portion of the first region while permitting the radio waves to reach a second portion of the first region. A controller is configured to select a tag ID read via the first antenna as a target tag ID, designate the target tag ID by communication via the second antenna, and then write tag information via the second antenna to the wireless tag corresponding to the designated target tag ID.

Embodiments of the present disclosure generally relate to systems and methods for detecting misplaced items in an establishment. In one implementation, the system may include at least one processor configured to receive from at least one reader in the establishment, identification signals of tags read by the reader; determine current locations of the tags; and record the current locations of the tags. The processor may also be configured to access a designated location in the establishment for each of the tags; and determine, by comparing the current locations with the designated locations, a particular tag with a current location that differs from the designated location of the particular tag. The processor may also be configured to generate a notification signal when the current location of the particular tag does not match the designated location of the particular tag.

A device for coding HF transponders moving along a conveyor device. The device includes a first machining station, arranged and designed to identify a respective HF transponder being guided past the first machining station, and a second machining station with an HF antenna. The HF antenna has a transmission region that is arranged and designed to simultaneously detect a plurality of the HF transponders being guided past the second machining station by the conveyor device. The second machining station is additionally designed to select a respective HF transponder detected in the transmission region of the HF antenna for transmission of data and to transmit data to the selected HF transponder, where the transmitted data is ascertained on the basis of the identification of the selected HF transponder by the first machining station.

One embodiment of the present invention relates to a method for a reader to transmit and receive a signal to and from a tag, the method comprising: a step in which a first reader transmits a first signal to a tag; and a step in which the first reader receives the first signal reflected on the tag. The timing for the first reader to transmit the first signal is determined by using an offset value based on an ID related to the first reader.

Layout generation for location-tracking sensors is disclosed herein. An example method in a computing device includes: receiving a map defining a set of features of a facility; obtaining layout data corresponding to the facility, the layout data defining, for each of a plurality of location tracking sensors, a location in a facility coordinate system; in response to deployment of the location tracking sensors in the facility according to the layout data, obtaining a performance metric for each of the location tracking sensors; and updating a primary layout generator according to the map, the layout data, and the performance metrics.

A system for monitoring a storeroom includes at least two radio frequency identification (RFID) readers/antennas that are configured to detect RFID tags attached to items or individuals. The RFID readers/antennas are positioned and configured to sequentially detect an RFID tag attached to an item or an individual as the item or individual moves into or out of a storeroom. The order in which the two RFID readers/antenna detect the RFID tag provide an indication of whether the tagged item or individual is moving into or out of the storeroom. A processing system coupled to the RFID readers/antennas can monitor the movement of goods and individuals into and out of the storeroom and automatically update an inventory of the storeroom based on the determined movements of goods and individuals.

A system of identifying and tracking occupants of a building is provided. The system includes multiple detector devices that each receive an identification signal from an identification device and multiple image capture devices that each output an image signal depicting a respective monitored location of the building. The system further includes a processing circuit that receives the identification signal from one of the detector devices, associates the detector device with a detector location, retrieves a user attribute, and receives the image signal from one of the image capture devices depicting a monitored location corresponding to the detector location. The processing circuit further generates an annotated video signal including the user attribute overlaid on the video signal, and displays the annotated video signal on a display device.

An inventory management system and method using RFID tags for the tracking and management of individual items of inventory or work-in-process. The system uses a cloud-based service device to manage inventory at a facility via a communications hub. RFID printers, RFID readers, and antennas located at the facility relay information through the communications hub. Movement of items is monitored by tracking RFID tags associated with each item. Information on the tracked items may be recorded, displayed, and used to generate reports and notifications by the cloud-based services device. Historical tracking records may also be displayed.

Techniques described herein are directed to, among other things, wireless payment readers configured to transition between multiple different power states. In some instances, these power states include one or more relatively low-power states such that an overall battery life of the wireless payment readers are lengthened. Further, in some instances, a point-of-sale (POS) application operating on a POS device that wirelessly couples to an example wireless payment reader may cause the wireless payment reader to transition from one state to another, such as from a first, lower-power state to a second, higher-power state in response to the POS application determining that a payment is to be processed using the wireless payment reader.
