RFID tag reader WIRED

Hi all
i found Home Assistant Tags - Home Assistant
for the use of an rfid tag.
BUT this require a power supply to each reader… and use a radio channel.

Is there a WORKING alternative to be wired to commercial bus (like knx) AND also working in HOASS ?
What I means is: Is it possible to read data from commercial tag reader, like knx mifare tag reader ?

Thanks in advance
