A computing system can receive input data and location data from a computing device of a requesting user of the transport service. Based on a destination location as specified by the input data and the current location of the requesting user, the system can determine, for each respective transport option of a plurality of transport options, an upfront cost for transporting the requesting user to the specified destination location using the respective transport option. The system may then transmit update data to the computing device of the requesting user to cause the computing device to automatically update a graphical user interface to include a plurality of interactive graphic features indicating the upfront cost for each respective transport option.

Data valuation leveraging techniques in a sensor data environment are provided. For example, a method obtains, at a gateway, at least one value computed by at least one data valuation algorithm for at least one sensor data element generated by at least one sensor associated with a set of one or more sensors operatively coupled to the gateway. The method then leverages, by the gateway, the at least one value computed for the at least one sensor data element.

In some arrangements, product packaging is digitally watermarked over most of its extent to facilitate high-throughput item identification at retail checkouts. Imagery captured by conventional or plenoptic cameras can be processed (e.g., by GPUs) to derive several different perspective-transformed views—further minimizing the need to manually reposition items for identification. Crinkles and other deformations in product packaging can be optically sensed, allowing such surfaces to be virtually flattened to aid identification. Piles of items can be 3D-modelled and virtually segmented into geometric primitives to aid identification, and to discover locations of obscured items. Other data (e.g., including data from sensors in aisles, shelves and carts, and gaze tracking for clues about visual saliency) can be used in assessing identification hypotheses about an item. Logos may be identified and used—or ignored—in product identification. A great variety of other features and arrangements are also detailed.

Various examples of the invention conduct a purchase transaction with a first sensor that senses removal or return of a first item from a first region; a computer vision sensor that senses removal or return of a second item from the first region; a transaction detector that determines an accuracy that the sensed removal or return of the first item by the first sensor and the sensed removal or return of the second item by the computer vision sensor correspond to a single event of removal or return of an item by a consumer and that forwards, to a machine learning tool, information associated with the sensed removal or return of the first item by the first sensor and information associated with the sensed removal or return of the second item by the computer vision sensor when the accuracy is less than an accuracy threshold; the machine learning tool that verifies or corrects the information associated with the sensed removal or return of the first item or the information associated with the sensed removal or return of the second item and provides verified or corrected information to the transaction detector; and an automated billing processor, coupled to the transaction detector, that applies a purchase price of the item against an account of the consumer for the item based on the verified or corrected information, thereby completing the purchase transaction.

Disclosed herein are systems and methods for managing transaction disputes. Techniques include accessing a transaction pattern model associated with a user account; detecting deviation of a transaction from the transaction pattern model; transmitting, based on the detected deviation, transaction data to a user device; receiving an input at the user device in response to the transmitted data; generating, based on the received input, dispute data; storing the dispute data; monitoring data extracts associated with the user account; detecting, based on the monitoring, a data extract indicating a posted state of a transaction associated with the dispute data; and updating the dispute data based on the data extract indicating the posted state.

A shopping cart scanning device, including a main body, a scanner disposed on at least a portion of the main body to scan a machine-readable code of at least one item, a scale movably disposed within at least a portion of the main body to receive the at least one item thereon, such that a weight of the at least one item is determined, a display unit disposed on at least a portion of the main body to display at least one of a price of the at least one item in response to the scanner scanning the at least one item and the weight of the at least one item in response to the scale receiving the at least one item thereon, and a cart clip disposed on at least a portion of the main body to removably connect the main body to a shopping cart.

An electronic shelf label wake-up method comprising: receiving an electronic shelf label wake-up instruction sent by a server; determining-target feature information of all electronic shelf labels to be woken up, and constructing a wake-up data packet according to all of the target feature information; and sending the wake-up data packet to all the electronic shelf labels so as to wake up the electronic shelf labels corresponding to the target feature information. In the present application, a plurality of electronic shelf labels can be woken up at the same time, and the efficiency of waking up electronic shelf labels in batches is improved.

Systems and/or techniques for facilitating relay attack prevention for electronic quick response (QR) codes are provided. In various embodiments, a system can determine a cardinality and a frame rate. In various aspects, the system can transmit a first electronic instruction to a mobile device, which can cause the mobile device to generate a set of interlaced frames having the determined cardinality. In various cases, the set of interlaced frames can respectively correspond to a set of portions of an electronic QR code, such that different frames from the set of interlaced frames depict different portions from the set of portions of the electronic QR code. In various aspects, the first electronic instruction can further cause the mobile device to sequentially render, at the determined frame rate, the set of interlaced frames on an electronic display of the mobile device. In various aspects, this can cause one portion from the set of portions of the electronic QR code to be depicted on the electronic display at a time. In various instances, the system can transmit a second electronic instruction to a point-of-sale device, which can cause the point-of-sale device to reconfigure scanner settings of the point-of-sale device, and which can enable the point-of-sale device to capture the set of interlaced frames sequentially rendered on the electronic display of the mobile device based on the determined cardinality and the determined frame rate.
