A controlled dispensing system includes a dispensing fixture and a server system coupled to the dispensing fixture and a mobile device via a communication network. The server system receives from the mobile device identification data of a user of the mobile device, verifies an identity or age of the user, and receives a request to reserve a controlled product included in the dispensing fixture. In accordance with the verifying of the identity or age of the user and the request to reserve the controlled product, the server system transmits to the mobile device dispense approval data including user validation and product selection information. The dispensing fixture obtains via an input peripheral a dispense code provided by the mobile device, the dispense code corresponding to the dispense approval data, and in accordance with the dispense code, causes a dispensing mechanism to dispense the controlled product.
