Abstract: A reorder device having an item tag reader and one or more sensors may facilitate the automatic reordering of an item for a customer. The item may be associated with an item tag that is placed on (or near) the reorder device. The reorder device may detect the item tag and transmit such data to an entity device, which may associate the reorder device and the item. The reorder device may periodically obtain weight measurements of the item that is placed on the reorder device, as well as a timestamp that indicates a time at which the weight measurements are obtained. Such data may be provided to the entity device, and an entity associated with the entity device may determine whether weight measurement satisfies an item threshold value. If so, additional inventory of the item may be ordered and delivered to the customer, without additional input from the customer.
