Accsess Control System Integration

Good Evening Community,

after days of searching i couldn´t find a workaround to get a Keypad/NFC-Reader/Fingerprint Reader integrated in HomeAsssistant.
At least i dont need a managemnt from user in homeassistant, a working entity that comes from the keypad that can controll my locks and doorbell would be eugh at the moment.

Does anyone have an idea to get it done?

Most integrations are for equipment from particular manufacturers, rather than for generic devices. What Keypad/NFC-Reader/Fingerprint Reader are we talking about?

i dont have any specific, tried tuya based but couldnt connect them with tuya, actually i got the new switchbot keypad vision even with the online integration no device is discoverd…
