Help me!!! for RDM6300 code.

hello friends, anyone can help me finish the coding of RFID? I designed six pieces of the door, which can only be opened by the holder of the RFID tag, and only use 1 piece RFID (I use RDM 6300) for reader, so it's like this for example: door A can only be opened by the cardholder A and door B only can be opened by the card holder B, C doors can only be opened by the holder of the card C, and so on as it is, please help,
Thank you.

Have you written any code?

I get this code from the internet, this code reads two pieces of tag just for entry or exit, represented by the two LEDs, I’ve tried to modify the coding of this suit my needs, tp I could not finish, because I was a novice to use arduino.
