RFIDuino

This is the Arduino Ethernet based RFID Reader System.

The system is using RFID Reader,  Arduino Uno, Ethernet Shield & PHP/MySQL/Apache. It works as below.

1. Reader sends data to Arduino
2. Arduino sends data to web server
3. PHP

A. Decodes Card Data

B. Checks date

C. Checks database for card #, if user is active, if they are allowed in today@current time

D. If access granted

i. Log user info to database

ii. Send “Open Password” Over UDP to the sending Arduino

iii. Arduino decodes UDP Packet

a. If “Open Password” is correct, send signal to transistor which will close the strike’s ground circuit and open and change led.

b. If “Open Password” is incorrect, do nothing.

iv. Send “Flush” packet over UDP to the sending Ardiuno

E. If Access Denied

i. Log user info to database

ii. Send “Flush” packet over UDP to the sending Ardiuno
