Abstract: Various implementations disclosed herein include devices, systems, and methods that match image portions of a first set of image portions and image portions of another set of image portions. This may be performed in a such a way that the sum of descriptor distances of the matched image portions is optimized in a globally optimal way. In some implementations, the matching is subject to one or more constraints, e.g., ensuring that each image portion of the first data set is matched with at least one image portion of the second data set and ensuring that each image portion of the second data set is matched with only one image portion of the first data set.

Abstract: Various implementations disclosed herein include devices, systems, and methods for verifying that an image includes a complete code of a time-varying visual marker that displays codes sequentially on a display. In some implementations, the verification determines that the image include a complete code rather than combinations of sequentially-displayed codes that may be included in an image based on use of a rolling shutter (e.g., in a camera of a detecting electronic device). In some implementations, the verification involves comparing a first verification portion of an image to a second opposing verification portion of an image. Various implementations disclosed herein include devices, systems, and methods for modifying image capture parameters (e.g., frame rate) to ensure capture of all codes of a time-varying visual marker.

Abstract: A scanning device includes a scanner, a fixing seat, a sensor, and a processor. The fixing seat is provided with a positioning groove for fixing a position of a workpiece. The sensor senses whether the workpiece is on the fixing base. The processor is communicatively coupled to the scanner and the sensor and used for receiving signals from the sensor and sending instructions to the scanner. If the sensor senses the workpiece on the fixing base, the processor controls the scanner to scan an identification code on the workpiece. If the sensor does not sense the workpiece on the fixing base, the processor controls the scanner to stop scanning.

Abstract: Systems and methods to validate RFID counts may be provided. A business may affix temporary or permanent location tags with barcodes throughout an area to be counted, and the location tags may then be recorded. Manual counters may perform a piece count of items associated with each location tag. RFID counters may perform an RFID read of items associated with each location tag.

Locations may be rejected where the totals do not match. Locations rejected by the manual piece count comparison may then be barcode scanned and compared to the RFID reads for each location tag required to be barcode scanned. Resolution may be performed for locations where the barcode item counts do not match the RFID item counts.

Abstract: A card reader includes a digital connector such as a Universal Serial Bus (USB) plug or an Apple® Lightning® plug. The digital connector includes a corresponding connector interface, which provides voltage to at least a card reader interface and an integrated circuit (IC) of the card reader. The card reader interface outputs an analog transaction information signal upon reading the card.

The audio signal can then be sent to the connector interface, which converts it into a digital signal such as a USB or Apple® Lightning® signal that is sent by the digital connector to a mobile device. Alternately, the audio signal can be sent to a microcontroller that converts the audio signal to a digital format such as USB, and then to the digital connector.
