writing data using C++ in RFID tag's microchip

[xenoviaquarta]

we are going to have a defense in this sem's subject.
we decided to make an ID system and im the programmer in my group.

has anyone know about writing data in RFID tag's microchip?
ive read a lot about RFID. and i think i understand now and how it works and how it use and i know it needs database.

my question is where should i start writing into it from scratch? i dont have any idea.


thanks in advance :)

That all depends on your schema, doesn't it? The most simple RFID chips transmit a locally stored GUID number when they are close to a sensor, while more advanced ones receive a hash from the reader, compute it and return a response. Either way you should start with a database. MySQL is popular, easy enough to learn and has a C style API.
