Our security system is a stand alone device that allows access to registered users identified by their magnetic cards.(For this project, "access" is represented by a lit LED, showing how the system could be used to control an external locking mechanism.)The system includes features such as:
- Multiple accounts, including Administrator accounts (which can create, modify, or delete the other accounts). The account information is stored in non-volatile EEPROM memory, so that it is maintained even if the system is reset.
- A "lock down" of the system when someone tries to gain access by repeatedly swiping incorrect cards.
- A 20x4 LCD display to give the user feedback on the current state (such as "Access allowed." or "try swiping the card the other way.") and to prompt administrators for commands. All messages printed to the LCD are simultaneously transmitted to an RS232 port, so that all activity can be logged by a PC.
