The device may also include a digital camera to capture an image of a face of an attempted user to enable facial recognition to alter a locked state of the device.

An electronic smoking article, a method of manufacturing an electronic smoking article, and a method of achieving a smoking experience without combusting tobacco are disclosed. The electronic smoking article includes an authenticated first section, which includes an aerosol generation unit having at least one heater; an authenticated second section, which includes a power supply operable to apply voltage to the at least one heater for heating a liquid in at least a portion of the aerosol generation unit to form an aerosol; and a conductive ink circuit embedded within the first and second sections, and wherein the power supply and the aerosol generation unit are electrically connected upon joining the first and second sections, and wherein each of the first and second sections has a portion of the conductive ink circuit.

Provided is an aerosol generating device including a heater configured to generate an aerosol by heating an aerosol generating substance; and a controller configured to control power supplied to the heater, wherein the controller distinguishes a first section, a second section, and a third section and controls power supplied to the heater, and calculates a control reference ratio by using at least two from among the first section, the second section, and the third section and controls power supplied to the heater based on the calculated control reference ratio.

A Personal Smoking Cessation (PSC) device, including an e-liquid cartridge, an EEPROM within the e-liquid cartridge, and a host body coupled to the EEPROM. The e-liquid cartridge stores a preselected fluid and a vaporization element to vaporize the preselected fluid. The EEPROM has a universally unique identifier (UUID) stored therein. The EEPROM authenticates a user, the e-liquid cartridge, and the preselected fluid. The EEPROM encrypts and decrypts data. The host body has a female USB-C connector coupled to a first male USB-C connector in the e-liquid cartridge. The male and the female USB-C connectors form positive mechanical and electrical connections between the EEPROM and the host. The host exchanges data with the EEPROM. The host includes an electronic lock. The electronic lock couples to a second female USB-C connector by which the electronic lock reversibly locks the EEPROM. The PSC device includes a Bluetooth radio transceiver coupled to the EEPROM.
