Revocable certificates for guestroom access and guestroom controls by mobile devices

Abstract

A system or arrangement of room control with a mobile device by a guest at a hotel, motel, or the like. When a reservation system assigns a guest to a room in, for instance a hotel, the reservation system may request a security certificate from a server that manages a control system in the room. The certificate may be transmitted to the guestroom control equipment and room reservation system. The certificate may be pushed to a mobile device of the guest. Also a key credential may be pushed to the mobile device for room access. The certificate may indicate the date/time period where the certificate is valid and functional aspects that the certificate can support relative to the room. When a guest goes to the room, the mobile device may link up with the control equipment in the room. Both entities having the same certificate can mutually authenticate each other.
