Rfid Based Attendance System With Sd Card Storing

DOWNLOAD ABSTRACT

AIM:

Design and development of RFID based attendance system with SD card storing.

PURPOSE:

There are so many attendance systems available in market. Finger print based attendance system is most widely used attendance systems. But those are expensive and need maintenance. We want to develop low cost attendance system with storing option. Here we proposed solution like RFID based attendance system with SD card storing.

DESCRIPTION:

This project includes RFID (EM-18 module), which is connected to Arduino through UART interface. SD card interface through adaptor through SPI port.

WORKING:

In this project each students have individual RFID cards. Each RFID card assigning to student name and roll number. When we swipe first time then Arduino takes as IN and second time swipe takes as OUT. This is nothing but entry and exit. This information will store in SD card. Also displaying on16X2 LCD display. For Invalid card buzzer will be ON.
