This invention relates to a system including a scale that weighs an item placed on the scale and encodes the weight and/or other item information into a machine readable code. The system may include a display that is coupled to the scale and displays the machine readable code. The scale may encode the item in Quick Response (QR) code format, Universal Product Code (UPC) format, and/or other computer-readable format. A mobile device may take a picture of or otherwise scan the machine readable code to determine the weight and/or other information encoded therein. The system may include a wireless transmitter that wirelessly transmits the weight. The mobile device may include a wireless receiver that wirelessly receives the weight transmitted from the scale. The mobile device may execute a self-scan application that uses the de-encoded or otherwise obtained weight for pricing the item based on the weight or other purposes.

Various embodiments herein each include at least one of devices, methods, and software for image guided scale calibration. One embodiment, in the form of a method, includes outputting an instruction to place a first weight on a scale being calibrated at a particular location and capturing at least one image of the weight when placed on the scale. The method then processes a captured image of a weight when placed on the scale to determine whether the weight is the first weight and whether the weight is at the particular location. When the weight placed on the scale is not the first weight or the weight is not at the particular location, the method performs a remedial action.

A barcode scanner should output one scanned result per scanned item at checkout. Scanners with large scan areas and multiple scan lines may scan an item more than once as it is dragged through the scan area during the checkout process. A timeout period, during which duplicate scans are ignored, may prevent duplicate scans from being transmitted. Scanners with integrated weight scales may require the use of the scan area for a weight measurement. As a result, weighed items may linger in the scan area longer than the regular timeout period and may be re-scanned. The invention embraces a method and system for mitigating this problem by using information from the scanned barcode and information from the scale to affect how duplicate barcode scans are handled for items requiring a weight measurement and not adversely affected with speed of input as may result with gating and virtual gating with disable/enable scanning commands.

A method for determining the reliability of a weighing result, a computer-readable medium, and a related system are disclosed. The method for determining the reliability of a weighing result includes: using an AI classification algorithm trained by data including event data related to a weight system and weighing data obtained by a sensor thereof, and making an inference about a weighing result, including providing latest data obtained by the same weighting system or a weigh system of a same kind to the AI classification algorithm, including latest event data and latest weighing data representing the weighing result. The method, the computer-readable medium, and the system disclosed herewith determine whether a weighing system is operating normally and whether displayed data is reliable.
