Secure Time Attendance System Software in PHP

The crisis of cutting-edge technology, and the manual orthodox attendance system outplayed by smart and secure biometric attendance using Arduino. Remote accessing application of GSM is incorporated in our proposed system, which sets serial communication of data between the GSM and Arduino UNO microcontroller board. To ensure its novelty, a prompt GSM SMS alert is also introduced in our work. The SMS content can be modified and saved according to users. The text message which is to be sent to the parents along with the number of individuals to be informed can also be increased. RTC DS3231 (real time clock) is used here in order to keep the system updated with current time and date and the other major role of RTC here is to keep the record of exact time/date at which the students have given their attendance, resulting no manipulation is possible to outplay fraud attendance mechanism. Unlike other biometric GSM alert-based systems, the usage of only one software for fetching the attendance data, matching with database and sending SMS alert; eventually reduces 55% memory usage.
