Examples provide a tag manager component that identifies a plurality of stationary RFID tags located within a three-dimensional space outside an item display area based on an analysis of RFID tag data associated with the plurality of RFID tag readers. A zone detection component analyzes item data associated with a plurality of items corresponding to the plurality of stationary RFID tags and location data associated with the three-dimensional space using a set of per-item criteria. The set of per-item criteria includes a per-item minimum threshold number of items per unit of three-dimensional space and/or a minimum threshold stationary time-period. A verification component analyzes sensor data and/or transaction data to verify whether the three-dimensional space is a termination zone. If the three-dimensional space is a termination zone, an inventory manager component removes the plurality of items from perpetual inventory.

Some embodiments provide RFID tag reading systems comprising: multiple sets of RFID readers at a retail shopping facility; a tag evaluation control circuit communicatively coupled with the multiple sets of RFID readers and at least one memory, and configured to: receive RFID tag information from the RFID readers; obtain and apply a first set of rules and identify a transition area within the retail shopping facility based on the received RFID tag information; identify a first set of RFID readers configured to read RFID tags as they move through the identified transition area; obtain and apply a second set of rules and establish a first null area adjacent the transition area configured to enable RFID tags crossing through the first null area and prior to entering the transition area to be in a predefined state when entering the transition area.

Systems and methods of establishing RFID null zones in detecting products in a retail environment

In some embodiments, systems and methods are provided to track objects at a retail store, comprising: a mobile RFID transmitter system comprising an array of RFID tags; multiple RFID tag readers; a tracking control circuit communicatively coupled with the multiple RFID tag readers, and configured to: receive, from a sub-set of RFID tag readers, RFID tag information of each detected first set of RFID tags of the array of RFID tags; obtain a first set of rules and evaluate over time the received RFID tag information and identify over time threshold changes from a set of base information of received RFID signals from the array of RFID tags, wherein the threshold change is consistent with a first object traveling between the array of RFID tags and a corresponding one of the first sub-set of RFID tag readers; and track the first object.

An electronic shelf label system comprising a plurality of electronic shelf labels is provided.

Methods and systems for an electronic shelf label system

In some embodiments, apparatuses and methods are provided herein useful to updating an inventory database. In some embodiments, a system for updating an inventory database comprises an array of RFID readers positioned at different locations about the retail facility, where the RFID readers are configured to read RFID tags associated with products, and a control circuit, the control circuit configured to receive, from one or more RFID readers, identifiers, wherein the identifiers are associated with the RFID tags, determine, based on the identifiers, a flow of RFID tags, identify, without reference to a structural map of the retail facility, a transition point from the stockroom to the sales floor, determine, based on an RFID read, that a product has passed through the transition point from the stockroom to the sales floor, and update the inventory database to indicate that the product is located on the sales floor.

System and method for identifying transition points in a retail facility

In some embodiments, apparatuses and methods are provided herein useful to monitoring RFID tags in a retail facility. In some embodiments, a system comprises an RFID tag, a first RFID reader monitoring a first zone and configured to determine, based on a signal received from the RFID tag, that the RFID tag is moving toward the second zone, transmit, to a second RFID reader monitoring the second zone, a notification indicating that the RFID tag is moving toward the second zone, and in response to receipt of a confirmation message from the second RFID reader, instruct the RFID tag to remain in its current state, and cease communication with the RFID tag, the second RFID reader configured to receive, from the first RFID reader, the notification, transmit, to the first RFID reader, the confirmation message, and transmit, to the RFID tag, a signal.

System and method for managing inventory via RFID tags

A method and a system for determining an amount of material remaining in a spool are provided herein. The system includes a radiofrequency identification (RFID) reader that is configured to read an RFID tag disposed at an end of a core of the spool. The RFID reader is provided on or in a vicinity of a support surface configured to hold at least a portion of the material. The system further includes a computer system in communication with the RFID reader, the computer system being configured to compute an amount of remaining material in the spool based on a thickness of the material and based on a number of revolutions of the spool. The number of revolutions is determined by a number of times the RFID tag on the spool comes in a reading vicinity of the RFID reader.

System and method for determining an amount of disposable material in a spool

In some embodiments, systems, apparatuses, and methods are provided herein useful to monitoring condition compliance. In some embodiments, an RFID tag comprises a first chip and a second chip, an antenna, a switch, wherein the switch is configured to switchably connect the first chip and the second chip to the antenna based on occurrence of a condition, a memory device, and a control circuit configured to write, in response to a connection between the first chip and the antenna, a first marker and an indication of a first state to the memory device, write, in response to a connection between the second chip and the antenna, a second marker and an indication of a second state to the memory device, determine an amount of time in which compliance was not met, and transmit, to an RFID reader, an indication of the amount of time in which compliance was not met.

Systems and methods for monitoring condition compliance via RFID tag

In some embodiments, systems, apparatuses, and methods are provided herein useful to monitor a shopping facility. The shopping facility can include an array of radio frequency identification (RFID) readers distributed throughout the facility to thereby receive and read signals generated from RFID tags within the facility. RFID tags can advantageously be coupled to and associated with products within the facility so that readings of the tags can be used to monitor the status of the products. A control circuit can be coupled to the RFID readers to thereby analyze the readings and compile readings over time. With this, the control circuit can monitor the shopping facility to identify scenarios requiring follow up. Upon identification of one of the scenarios, the control circuit can instruct an automated ground vehicle (AGV) to inspect an identified product at a location within the facility. The AGV can operate a sensor thereof to determine a status of the identified product.

Radio frequency monitoring of a shopping facility

In some embodiments, apparatuses and methods are provided herein useful to monitoring a plurality of RFID tags in a remote location. In some embodiments, a garment for monitoring a plurality of RFID tags in a remote location comprises a garment body, an RFID reader attached to the garment body, the RFID reader configured to read the plurality of RFID tags in the remote location, an antenna attached to the garment body, and a control circuit attached to the garment and configured to receive, from the RFID reader, one or more identifiers, wherein the one or more identifiers are associated with the plurality of RFID tags, generate, based on the one or more identifiers, emulated identifiers, determine that the garment is within a designated area separate from the remote location, and in response to determining that the garment is within the designated area, cause the emulated identifiers to be transmitted.
