Abhishek Goyanka / Mbed 2 deprecated RFID_Attendance_System

This is a RFID based attendance system. The current program is only for two users but can be easily scaled for more users. Apart from FRDM-K64F board, we have MFRC522, Nokia 5110 LCD and SD card as external hardware. Each time a legitimate card is flashed the name of the person will be displayed on the LCD and his information will be stored in SD card if it's already not there. I have used existing libraries for all the harware. Here is the list. MFRC522 - By Martin Olejar SDFileSystem - By Andrew Lindsay NOKIA_5110 - By Chris Yan.

Dependencies:   MFRC522 NOKIA_5110 SDFileSystem mbed
