Abstract: A rack assembly for use with an automatic retail device. The rack assembly includes a rack body comprising and a load bar configured to mount to the rack body. The rack body includes a fastening element configured to mount the rack body to a portion of the automatic retail device and a main shelf controller disposed within the rack body and in communication with a microcontroller of the automatic retail device. The load bar includes a weight sensor configured to sense a weight of products positioned on the load bar and a circuit board. The circuit board is disposed on the load bar and in electrical communication with the weight sensor and the main shelf controller. The circuit board transmits a signal corresponding to the weight sensed by the weight sensor to the microcontroller via the main shelf controller.

Abstract: A method of interacting with an automatic retail device, including receiving user identification information at the automatic retail device and receiving confirmation of the identity of the user from a source external to the automatic retail device. The method further includes determining the contents of the automatic retail device at a first time, determining the contents of the automatic retail device at a second time, transmitting data regarding the determined contents of the automatic retail device to a server at both the first and second times, and prompting the user to respond to an inquiry.
