i watched this Video on Youtube.

This is exactly what I want, i want to open a Danalock or similar Smartlock with an Rfid-Reader.
However, I have no experience with the matter yet. Has anyone already implemented such a possibility and can help me? What hardware / software is required for this? It does not have to be that the RFID reader is invisible.
I have already written to the uploader on Youtube, but he does not answer.

Thanks in advance
