Abstract: Techniques related to dispenser supply management are disclosed. A dispenser holds sets of different dispensable items. In response to selection of an individual item from one of the sets, means in the dispenser controllably dispenses the individual item. A computer system periodically receives one or more data transmissions indicating that a particular packaged item is stored in the dispenser at or near a time of receiving the one or more data transmissions. Based on a cessation of the one or more data transmissions, the computer system determines that the particular packaged item is missing from the sets of different dispensable items in the dispenser. In response to determining that the particular packaged item is missing from the dispenser, the computer system automatically generates and transmits, toward a recipient computer system via a computer network, a digital electronic message that includes a request to resupply the dispenser with packaged items.
