Abstract

With an upsurge of data by global brands to interact/reach prospective clients, the birth of the Internet has today bridged the information gap. Virtualization techniques are today utilized as means to bridge the various lapses in our human processing endeavors. The adoption of tech to perform a variety of functions has since become imperative to ease our daily living as well as seamlessly allow transformations of various kinds to be impacted on our society. Study proposes a virtual key card access with cost effective and cheap solution for managing access to areas within a facility. We have successfully integrated IoTs, virtual key card access, web access control, solenoid lock integration, and ESP32 controller to create a comprehensive access control system. Its benefits over traditional key include better security, user data privacy, system efficiency, and user convenience. The system also provides real time monitor and control capabilities that will allow administrators to track and manage access to the facility remotely. And in turn, enhancing system's security and efficiency.
