Analog RFID tag to reader interface using a microcontroller:

When the Arduino is connected to the tag and the reader, it can send and pick up the binary signal.  It can even display the signal as it is picked up.  The problem is that the Arduino is having problems saving or writing the reader signal so that it can be used with the code written for the tag and reader circuit.  The tag can be used as any tag desired by simply changing the transmitted information.  The programming for the reader, however, has to have the other tag ID's and information stored so that when it is restarted for a new tag, it knows what to do with the information.

Positional Tracking:

The frequency used is not capable of functional positional tracking applications.  125 kHz RFID applications typically have a range of cm. Close range is important for the access control and bench assignment applications of our current system.  It is undesirable that a student walk by and set off the door or assignment reader.  For positional tracking, higher frequencies with meter ranges are used.  The most common is 900 MHz.  A separate tag and reader component would have to be built in order to achieve positional tracking.

Lighting Control:

With time constrictions, there wasn't time to build an electronic switch for a lighting circuit. The type of switch used for the door strike would not suffice because the power rating for the circuit is too low.  We would just need a high power relay circuit that would apply the proper 110 V to the lights when supplied amplified power from the Arduino.
