Door-access control is a physical security system that secures a room or building by limiting access to specific people and keeping records of such accesses. The significance of iris technology among others, for security and access control applications are numerous. In terms of physical security, iris technology is already making inroads into the access control market because of the reliability of its authentication process. In this paper, the researchers present an aspect of the system relating to the design and construction of an iris biometric door access control. The system was developed as a means of getting into a specified area by securing the door and limiting access. The database created contains the particulars of those allowed access in order to work in tandem with the mandatory iris authentication process. The implemented design worked satisfactorily
