This document summarizes the Card Swiping and Password Authentication Security System (CSPASS). The system uses an AT89C52 microcontroller, optocoupler, keys, relay, buzzer, and LCD display. It requires a user to swipe their card which is read by the optocoupler, then enter a password on the key matrix which is authenticated before a relay is activated, granting access. Power is supplied through a transformer, rectifier, and voltage regulator to power the various components.
