Apparatuses, systems, and methods are described that relate to location-based indications. An apparatus may include a frame, a sensing device, and a computing device. The frame may include a first set of members spaced apart and oriented in a first direction. At least one member of the first set of members may include an indicator area. The frame may also include a second set of members spaced apart and oriented in a second direction. At least two members of the second set of members may extend between the first set of members to define a container receiving area. The sensing device may be disposed adjacent to the container receiving area and configured to detect movement of containers with respective to the container receiving area. The computing device may be communicatively coupled to the sensing device and configured to cause presentation of indicators within the indicator area.

Container holding fixtures

Embodiments herein describe an RFID reader tray which includes a receptacle for detecting RFID tags disposed on physical items. In one embodiment, a sidewall is disposed around the periphery of a bottom support structure and extends away from the bottom support structure to form the receptacle. The reader tray includes an RFID antenna disposed under the bottom support structure on which the items can be placed. The material of the bottom support structure is selected such that RFID signals emitted by the RFID antenna can radiate through the bottom support structure and reach RFID tags placed on items in the receptacle. In one embodiment, the reader tray includes a shield for reflecting the RFID signals so that the most of the RFID signals radiate through the bottom support structure and into the receptacle.

Mobile tray for performing RFID reads

Methods and systems are disclosed that relate to causing indicators to present indications. Sensor data associated with a space of a fixture that includes a set of slots may be received. The sensor data may indicate that a sensor has sensed a condition of a container relative to the space. It may be determined that the condition corresponds to a slot of the set of slots based at least in part on the sensor data. Information usable to associate the container with a record may be generated. An indicator corresponding to the slot may be caused to produce an indication.

Generation and presentation of location-based indications

Features are disclosed for a wearable scanning device that can passively initiate scanning for wireless identifiers such as RFID tags. The wearable scanning device may include a force sensor, an accelerometer, or a motion activated switch that can initiate the scanning when detecting an action performed by an associate (e.g., lifting) without an express intent from the associate to scan.

Wearable passive scanning device

Features are disclosed for collecting wireless identifier signals such as from RFID tags to accurately determine the location of items associated with the wireless identifier. Carefully coordinating when to begin and end collection of the signals and analysis of the signals and signal characteristics (e.g., received signal strength) allow a carried item to be identified and its location determined. Additional features are described to further validate the location of the item.
