You actually get your new certificate from the doctor. After speaking to him on the phone, then they mail it to you. If you need to renew your mm card you do that online at the state site with your new certificate number then they mail your new card to you.
It's done by the doctor. You just go with your new script and they will fill it. It's all online now. At least, that's how it went for me when mine was just renewed this February.
