Memory Key

May 21st, 2014

I need every information on what will be considered before writing a driver for Key Card encoder using Java?

I want to develop a program to communicate with key card encoder through the serial port using Java such that cards will be encoded to open a door via the interface.

My problem now is; what will be done to the door key so that the encoded card will open it and how?
Will the door key be pre-programmed before or after installation?
Can I just buy any encoder in the market and start developing a driver for it?

Please I need even more info on this because I have 3 months for my project
card access door system is what I am referring to here

key card adapter for Nintendo Wii is used to copy game. Feature: Generic high quality SD memory key card.
