I'm using javaxsmartcardio at the moment but I don't know how this library works. I have an acr122u reader/writer and I only want to use it as writer so that I can write cards and read them on my RFID doorlock project with rdm6300 card reader. So far I've managed to read 2 cards which both were written to be used in social utilities. That's why I've written my arduino code according to 1 card is autherized and the other is not. But I want to write my own cards and put my own specific password so only the cards I give autherization will unlock the door. I'm all set with the doorlock part but I'cant write my own cards.Please help me out. Thanks in advance.

Mifare uses 13.56 MHz. The RDM6300 is 125 KHz.

You'll need to replace one to be compatible with the other for your project.
