Abstract: A barcode-reading device can send barcode images to a remote server for decoding. A decoder on the remote server can process the images and attempt to decode any barcodes in the images. Once the decoder on the remote server has successfully decoded a barcode, the remote server can send the decoded data back to the barcode-reading device and/or to a host computing device that is communicatively coupled to the barcode-reading device. If the barcode-reading device receives the decoded data, the barcode-reading device can forward the decoded data to the host computing device. In some embodiments, a barcode-reading device can send all captured images to the remote server. Alternatively, a barcode-reading device can send only some captured images to the remote server. In some embodiments, a barcode-reading device can be configured to perform one or more preliminary processing operations on an image before sending the image to the remote server.

Abstract: A barcode-reading system utilizes a decodability machine learning model (MLM), which is configured to predict decodability of an image by a barcode-decoding module. A captured image is passed to the decodability MLM for processing before being passed to the barcode-decoding module. If the decodability MLM returns a decodability prediction which indicates that the image is likely to be decodable by the barcode-decoding module, then the image is passed to the barcode-decoding module. Conversely, if the decodability MLM returns a decodability prediction which indicates that the image is not likely to be decodable by the barcode-decoding module, then the image is discarded without being passed to the barcode-decoding module.

Abstract: An object includes an NFC tag, which includes NFC data. The object also includes a barcode, which is an encoded representation of barcode data. When someone wants to access the NFC tag data, the object is presented to an object-reading system that includes both an NFC reader and a barcode reader. The barcode reader is used to read the barcode on the object in order to obtain the barcode data contained within the barcode. The barcode data is then used to establish a secure communication channel between the NFC tag in the object and the NFC reader. The NFC reader then utilizes the secure communication channel to read the NFC tag in the object.

Abstract: The present disclosure describes techniques for improving image quality when a camera-based barcode-reading device is reading barcodes located on objects that are moving relative to the barcode-reading device. The techniques disclosed herein enable the image sensor in the barcode-reading device's camera to remain aimed at an object that is moving relative to the barcode-reading device while the camera is capturing an image of the object. Advantageously, the techniques disclosed herein can reduce image blur. In a barcode-reading device that includes a rolling shutter-type image sensor, the techniques disclosed herein can also reduce image distortion.

Abstract: A barcode reading application for a general-purpose computing device includes a motion detection module in addition to a decoding module. The motion detection module is configured to process image frames captured by a camera of the computing device for the purpose of performing motion detection. The barcode reading application can be configured so that the decoding module does not process captured image frames until motion has been detected in the camera's field of view. Because fewer processing resources are required for motion detection than for barcode reading, including motion detection capability in the barcode reading application can reduce processor usage in the computing device compared to a scenario where the decoding module is constantly processing captured image frames.

Abstract: A barcode-reading device can transmit data to a remote server when a decoding problem is detected. The data transmitted to the remote server can include captured images, barcode-reading device settings, and decoding metadata. The remote server can process the data and determine one or more potential causes of the decoding problem based at least in part on the results of processing the data. The processing performed by the remote server can involve the use of machine learning models that have been trained to identify image characteristics corresponding to decoding problems. Once a potential cause for a decoding problem has been determined, the remote server can perform at least one action to address the decoding problem. For example, the remote server can send one or more messages to notify certain individuals about the decoding problem and the potential cause that has been identified.

Abstract: A barcode-reading device can be configured to record certain information about events related to the barcode-reading device in a usage log. The barcode-reading device can be configured so that it records certain information in the usage log whenever the barcode-reading device scans a barcode (e.g., a timestamp, an indication of whether the barcode is successfully decoded, a symbology of the barcode, decoded data). The barcode-reading device can also be configured so that it records information about events that are not specifically associated with a barcode scan (e.g., when the barcode-reading device is powered on, when the barcode-reading device experiences a failure). The information contained in the usage log can be processed to determine statistics relevant to the barcode-reading device. The device statistics can be used for various purposes, such as improving the performance of the barcode-reading device, improving the user's experience with the barcode-reading device, and so forth.

Abstract: Data can be collected from a plurality of barcode-reading devices associated with an enterprise. The collected data can be distinct from the decoded data that is generated by the barcode-reading devices when barcodes are read. For example, the collected data can include device data describing one or more characteristics of the barcode-reading device. Other types of data (e.g., camera data, license data, decoding metadata) can also be collected. The collected data can be sent to a remote server for processing and analysis. The remote server can provide feedback to the enterprise based on the results of analyzing the collected data.

Abstract: The disclosure concerns systems and methods for controlling access to a device with barcode-reading functionality. Enabling the barcode-reading functionality of the device may require providing authenticating information. A user may provide the authenticating information using an identification card with an embedded near field communication (NFC) tag. After the device or a charger of the device validates the embedded NFC tag, the device may enable the barcode-reading functionality but track an amount of time since a last barcode scan of the device. If the amount of time since the last barcode scan reaches a present period, the device may disable the barcode-reading functionality. The device may send a connection request from a portion of a local area network (LAN). A server may receive the request. The server may deny the device access to the LAN if the device is not authorized for use in the portion of the LAN.
