I was able to design, construct and test a fingerprint attendance system based on ESP32 microcontroller. All the requirements that I had set at the commencement of the project are met by the system. The main results of this project are: An all-fingerprint enrollment system, which records two scans of each fingerprint, makes sure that the scans are identical and stores the template in the sensor memory. The system recognizes all the fingerprints that have been stored in the flash memory of ESP32 using the student ID and name. A system where there is an attendance marking system which can only be initiated by the professors. The learners can mark attendance only when the session is in progress and the system will not permit a student to mark attendance on the same day or session. LCD front end to guide the user through all the functioning with clear instructions and feedback. The enrollments, marking attendance and deletions can be made without the user viewing a computer screen. A...
