Abstract: Techniques for establishing a bidirectional wireless communication link between two otherwise detachable devices when these devices are physically joined together for use as a physically joined device are provided. An example method includes receiving by a mobile computing device a short-range wireless signal from an RFID reader device; monitoring, by the mobile computing device, an RSSI associated with the signal from the RFID reader device; and establishing, by the mobile computing device, a wireless communication connection to the RFID reader device based on the measured RSSI associated with the signal from the RFID reader device being greater than a threshold RSSI value, wherein the threshold RSSI value is calibrated based on an RSSI value associated with the short-range wireless signal from the RFID reader device measured by the mobile computing device when the mobile computing device is physically joined to RFID reader device for use as a joined device.

Abstract: In some implementations, a device may configure security tags. The device may receive, from one or more cameras associated with the device, image data associated with a product moving through a scanning zone of the device. The device may determine, based on the image data, a direction of movement associated with the product moving through the scanning zone of the device. The device may configure, via a reader of the device and based on the direction of movement associated with the product, a setting of a security tag associated with the product.

Abstract: Techniques for eliminating RFID cross-reads for RFID point of sale scanners using imager object tracking are disclosed herein. An example method includes measuring, by an imager a series of displacements of an object from a center of the field of view (FOV) of the imager, over a timeframe; measuring, by an RFID reader, a series of received signal strengths for an RFID tag over the same timeframe; comparing the series of displacements to the series of received signal strengths over the timeframe to determine a measure of similarity between the series of displacements of the object from the center of the FOV of the imager and the series of received signal strengths for the RFID tag over the timeframe; and responsive to the measure of similarity exceeding a threshold measure of similarity, adding a record associated with the RFID tag to a transaction log.
