A security checkpoint system and apparatus that provides security officers entrusted with protecting our nations' critical infrastructure or other high risk locations, a means of isolating and tracking suspicious persons who enter large public events or public transportation systems. Via a machine, communications system and components that are positioned at entrance points such as stadium section entrances, train station platform entrances, etc., a suspicious person entering the system is processed through a series of onsite as well as off-site follow-up investigations upon first being noticed as suspicious. The machine and it's overt security checkpoint system is designed to induce a suspicious reaction in persons with a guilty mind. As the person registers upon entrance to a facility, a close up view of the persons' face, as well as his seat assignment, is captured by the machine in digital image format. It is then sent by real-time transmission to security personnel in proximity to the location of the machine. A security officer positioned to spot persons manifesting suspicious behavior upon having to register at the machine, highlights the suspicious entrant electronically and sends an e-mail alert along with the digital images of both the suspicious entrant and his ticket, that also displays his seat number or destination, to on-site, as well as offsite law enforcement personnel for further review and investigation as necessary. As the system ties directly into the internet and can be sent to various law enforcement agencies for review, the resulting effect of such broad coverage of review of suspicious persons by law enforcement, makes this invention one of the most effective means of deterring terrorists and criminals in society today.
