Radio Frequency Identification (RFID) Card Readers provide a low-cost solution to read passive RFID transponder tags up to 2 inches away. The RFID Card Readers can be used in a wide variety of hobbyist and commercial applications, including access control, automatic identification, robotics navigation, inventory tracking, payment systems, and car immobilization. The RFID card reader read the RFID tag in range and outputs unique identification code of the tag at baud rate of 9600. The data from RFID reader can be interfaced to be read by microcontroller or PC. In this project, the RFID module reader typically contains a module (transmitter and receiver), a control unit and a coupling element (antenna). This module is interfaced with the micro controller and when the card is brought near to the RFID module, it reads the data in the card and displays on the LCD. If the data in the card is matched with the data stored in the program memory, then it compares and displays authorized message. If the data is not matched it displays unauthorized. For authorized message, the door will be opened and closes automatically after a small delay. If it is an unauthorized person it alerts the persons through a buzzer. The RFID module alerts the buzzer whenever it reads the data from the RFID card. The door will drive by DC gear motor by l293d driver. The significant advantage of all types of RFID systems is the non contact, non-line-of-sight nature of the technology. Tags can be read through a variety of substances such as snow, fog, ice, paint, crusted grime, and other visually and environmentally challenging conditions, where barcodes or other optically read technologies would be useless. This project can provide security for the industries, companies, etc. In this project 7805 is a regulator and it avoids noise spikes in power supply. RFID modem is connected microcontroller through serial port. These RFID modem works under 9600 or 4800 baud rates. 16X2 LCD connected to microcontroller through digital I/O lines.

According to ancient Greek scripts BIOMETRICS means study of life. Biometrics studies commonly include fingerprint, face, iris, voice, signature and hand geometry recognition and verification. Many other modalities are in various stages of development and assessment. Among these available biometric traits Finger Print proves to be one of the best traits providing good mismatch ratio and also reliable. Registering the attendances of students has become a hectic task as sometimes their attendance may be registered or missed. To overcome this problem i.e. to get the attendances registered perfectly, we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS. Firstly discussing about Biometrics we are concentrating on Fingerprint scanning. For this we are using FIM 3030N high voltage module as a scanner. This module has in-built ROM, DSP and RAM. In this we can store the fingerprints of up to 100 users. This module can operate in 2 modes i.e., Master mode and User mode. We will be using Master mode to register the fingerprints which will be stored in the ROM present on the scanner with a unique id. The fingerprint module will be interfaced with the microcontroller through serial interface. The images of the students of a particular class will be scanned and stored in the microcontroller. The students have to scan their images to register their attendance daily. When the student has to register his attendance on that particular day, he has to scan his fingerprint image. The fingerprint module scans the student’s image and passes the scanned image to the microcontroller. The controller reads the scanned image, compares this image with the already stored image. If both are matched, the student’s attendance will be registered for that day. If it is not matched, the student’s attendance will be marked as absent and buzzer indication will be given. By simply pressing a switch, we can get the list of absentees for that day. We can see details on 16X2 LCD. (In this project we can connect microcontroller to PC and PC maintain presents and absents list with help of C# application-But it is optional).
