Abstract: A distributed system uniquely tracks individual consumable items within a stream of commerce and tracks ingredients used in consumable items. The distributed system further provided tracks the sale of the consumable items to the consumer. A point-of-consumption system (e.g., juicer) is used to allow consumer access to the consumable item and the distributed system controls the point-of-consumption system to control access to the consumable item, including blocking use or providing an alert when a consumable item should not be consumed due to recall, expiry, allergy, or other reason.

Abstract: A distributed system is provided. The system includes a point-of-sale system adapted to conduct a transaction with one or more consumable items and a database coupled to the point-of-sale system over a communication network. The database is adapted to map the transaction with the one or more consumable items to an indicator of authorized entity. A point-of-consumption system is coupled to the communication network and is adapted to permit access to the one or more consumable items responsive to the indicator of an authorized entity.

Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for conducting and scheduling a communication session with a remote agent. A communication session can be scheduled using a scheduling interface configured to present scheduling data. Upon scheduling a communication session, the user can be sent a confirmation message including the details of the scheduled communication session. The user can enter the communication session via a launch page configured to allow entrance to the communication session during a scheduled time period. Prior to the time period, the launch page can present the user with a clock indicating the remaining time until the user can enter. Upon entering the communication session, the user is presented with a communication session interface enabled with a primary communication method. Communication methods can be added or terminated with terminating the communication session as long as one communication method remains active.
