introduction of gsm based exam gate authentication system
The Biometric based Exam Gate Authentication System with SMS Alert project utilizes the SIM900 module to send success and failure messages.
When a student is authenticated successfully, the system sends a success message to the exam supervisor's phone through the SIM900 module. This message confirms that the student has been granted access to the exam venue and allows the supervisor to keep track of the number of students entering.
On the other hand, if a student fails to authenticate, the system sends a failure message to the supervisor's phone via the SIM900 module. This message alerts the supervisor that an unauthorized person has attempted to access the exam center and helps prevent cheating and impersonation.
The use of the SIM900 module ensures reliable communication between the system and the supervisor's phone, even in areas with poor internet connectivity. This makes the Biometric based Exam Gate Authentication System with SMS Alert project a robust and dependable solution for exam security and integrity.
features of gsm based exam gate authentication system
1. Biometric Authentication: The system utilizes biometric data such as fingerprints to identify and authenticate students before granting them access to the exam center. This helps prevent cheating and impersonation during exams.
2. GSM900 Communication: The use of the GSM900 module ensures reliable communication between the system and the exam supervisor's phone, even in areas with poor internet connectivity.
3. SMS Alert: The system sends an SMS alert to the exam supervisor's phone whenever a student is granted access or denied access. This allows the supervisor to keep track of students entering the exam center and ensures that only authorized individuals are allowed in.
4. Arduino Nano: The system is powered by an Arduino Nano microcontroller board, making it cost-effective and easy to maintain.
