Card Based Access Control System
In Card Based Access Control System, a card is issued to an employee which holds a unique alphanumeric code. A unique code is assigned to every card which may match an employee’s company registration code and is strictly different for every card. this card is punched on the biometric machine and due to its unique code, the door gets opened as the code is on the name of that employee and this has been entered into the machine. Without this card, the entry would be restricted. Sometimes companies opt for both finger & card access if in case the employee forgets the card so he/she can enter the floor area with finger punch.
