Abstract: The system and techniques disclosed herein perform advanced and automatic age verification. The age verification system (AVS) is designed for automated and accurate age-restricted access control and age verification for the sale of age-controlled products. For example, the AVS can be employed to perform age-verification to permit the legal sale/purchase of age-controlled products such as alcohol, tobacco, cannabis, and the like, and Also, the AVS can be used to control legal access to age-restricted areas such as casinos, movie theaters, bars, and the like. The AVS can include a scanner for scanning a barcode printed on an identification (ID) card, an application, and a computer unit having output devices for generating visual, audible, and electronic signals to view, alert, and control age-restricted entry and control the sale of age-controlled products. The AVS can include automatic door lock functionality that supports age-restricted access control.
