  With the rapid advancements in technology, automation has emerged as the
future of human endeavors. From simple tasks like attendance management to
complex security systems, automation has the potential to revolutionize various
aspects of our lives. This research paper explores the implementation of a
method aimed at enhancing room security in hostels and automating class
attendance using ID cards. In this study, we propose a system that utilizes the
unique identity information stored in ID cards for various security and
check-in tasks. By integrating RFID (Radio-Frequency Identification) reader
technology, GSM modules, Node MCU, and Arduino, we create a comprehensive
solution. The RFID reader scans the ID card, extracting the relevant
information and verifying the user's identity. The data is then transmitted via
the GSM module to a central database, ensuring real-time monitoring and
security measures. Moreover, the system also enables the automation of class
attendance. By utilizing the same ID cards, students can simply tap their cards
on a reader placed in the classroom. This information is recorded
automatically, eliminating the need for manual attendance taking and reducing
errors and time consumption. This research project highlights the practical
implementation of ID card technology to enhance room security in hostels and
automate class attendance processes. By leveraging the power of automation, we
aim to streamline administrative tasks, improve security measures, and optimize
efficiency in educational institutions and other relevant settings.
