If you do a search on the words "add" and "user" you'd be surprised how many people have already asked this type of questions. A few of the PR## projects like keypad lock, RFID lock, finger-print lock almost all use the same algorithm to implement adding user names and Id tag. So read those first as a start to see if someone had already asked the same questions and problems are same as yours.

The next war will determine NOT who is right BUT what is left.
