Keycard reader systems are widely used in access management mechanisms in Large Hotels and Cruse Ships which has rooms with access control based on Keycards. These devices read an ID card, and grant access only when the card sends an approved code. These code tables are stored on a network server that must be queried every time someone attempts to use an access card. Rather than placing an entire PC workstation at the gate, using a wall mounted single port serial device server, is an easy and inexpensive way to implement the system. Our Device Servers can use for online verification and for punching the Keycards.

The Keycard Reader is to connect  EAD-01 and EAD-01  is to connect LAN. When a keycard inserted in to the reader the ID in the card is transmitted to server which validates the code. If the ID is valid server will send signal to open the door otherwise reader will flash a card rejection signal. The access control application software should be installed on a server in the main security office. Data from various Keycard readers are collected together and stores in the server so that every other system in the LAN can access real time updated information.
