Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for beverage dispensing. In one aspect, a client device requests activation of a beverage system at the given location. An authorization request is transmitted to a control terminal of a given location that includes a client identifier and requests confirmation that a user of the client device meets minimum age requirements for dispensing beverages provided by the beverage system. The confirmation is received that the user of the client device is approved to use the beverage system, and the beverage system is activated for use by the user of the client device, and a command is transmitted that is required to open a valve of the beverage system located between a beverage source and a beverage dispenser that controls beverage flow when the valve is open.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for control of beverage dispensing. In one aspect, authorization data specifying that a beverage dispensing node is authorized to be activated are received. Activation data that request activation of the node are also received, where activation of the node causes a valve that controls flow of fluid to a beverage dispenser to be opened. A determination is made that the activation data are associated with a user identifier for an enabled user, where an enabled user is a user that has been enabled to activate the node. In response to receipt of the authorization data and the activation data a valve that controls flow of fluid to the beverage dispenser is opened. Data (e.g., de-authorization or de-activation data) specifying that an activated beverage dispensing apparatus be de-activated can also be received. In response to receipt of the data, the valve can be closed.
