Abstract: Systems and methods of providing sign-in at entry to a retail store are performed. In one exemplary embodiment, a method is performed by a wireless device operationally coupled to a network node device and having processing circuitry operable to execute an application that is associated with both a certain user account of a set of user accounts and a set of retail stores. The method includes sending, to the network node device, an indication that includes both the current location of the wireless device and information associated with the certain user account to enable the network node device to initiate sending, to the wireless device over the network, a user account-specific, location-based notification that includes an optically machine readable code, displayed through the application executed by the processing circuitry of the wireless device, to enable entry to a certain retail store of the set of retail stores.

Abstract: A self-service computing device detects a first weight for an item positioned on a sensory platform and determines a stabilized weight and a weight-based item count. Responsive to determining the stabilized weight, the device causes image capture devices to capture images of the item, identifies a visual characteristic of the item, and retrieves, from memory, a second weight of the item. To generate an image-based item count, the device compares the identified visual characteristic of the item with the second weight of the item and validates the presence of the item. The device causes or blocks a self-service transaction operation at the self-service computing device depending respectively on whether or not the image-based item count and the weight-based item count correspond.

Abstract: A computing device retrieves a stabilized weight and a weight-based item count for one or more items to be purchased. Responsive to retrieving the stabilized weight, the computing device retrieves an image-based item count and an expected weight based on the image-based item count for the one or more items to be purchased. The computing device selects between authorizing and blocking checkout of the one or more items based on the weight-based item count, the image-based item count, the stabilized weight, and the expected weight.
