Smart gatekeeper using QR-code

Electronic gatekeeper is a web system that helps parents or car drivers to call their students from an educational institution. In traditional, this task requires security man to authenticate the man who wants to take his student from an educational institution, especially in the morning, this case has a lot of problems and issues. Our target is to take advantage of the technology to solve problems, save time, and effort. The proposed system started by a calling process done by a call from the parent or the car driver to the student by our system, then the name of that student will appear on a monitor inside the institution also the name will be spoken by speakers. Finally, the student can exit from the gate by passing a special and unique QR code card to get permission to leave the institution by our proposed Gatekeeper system.
