centralised MAC authenthication of lan and wireless clients

I’m trying to set users to authenticate only with their mac addresses without prompting for user name and password.I would also like to use radius for that,because I would like it to be managed from one place.I have users connecting both ways:wired and wireless.I also have a few points where few users are connecting through one ap in client mode to networks ap in ap-bridge mode and they should be managed separately.Is there any way to do this with mikrotik?

So I imagined it this way:Users connect to the network.Their mac is being checked.If they paid they can use all network resources,if they didn’t they have access only to a few addresses on a network (group chat,forum,homepage).Is it possible?
