Automatic Attendance Monitoring And Light On/Off System Using E-Card

Abstract

This project is developed for the users to monitor the attendance and to control a door through Electronic Card. It is a specially designed card. Each employee in the company will have the E_Card. The card is designed using logical values. Each card will have different logical value. The card holder(Slot), display and key pad are connected with the main door. As soon as an employee insert a card in to the slot, it evaluates the card and prompts about the password to check whether he is an authorized person or not. If he is an authorized person, the microcontroller sends signal to the controlling circuit to switch on the light. Thus the light glows automatically. It he is not an authorized person, the light will not be switched on and it generates a siren there by displays that he is not an authorized user. The microcontroller also sends signal to the PC through USART. It puts attendance for the particular user. This is very much used in companies where security and authentication are required. This project uses Assembly language as Microcontroller language.
