  • Patent number: 8941465
    Abstract: Secure door entry without a traditional card reader is made possible by tagging the door with an unpowered, unique token which can be read by a user's personal mobile electronic device. The user's device transmits both door and user identification to a remote server, where the decision is made whether to open the door. If so, the server sends an open door signal using the IP suite of protocols to an electronic bridge, which in turn passes the signal on to a door strike, opening the door. Another signal may be sent to an annunciator. Single-use digital tokens may also be used to open the doors. The permissions relating to doors or other physical assets may also be used to grant access to logical assets.

  • Patent number: 8907763
    Abstract: Mustering of persons from a building in an emergency situation is made possible by tagging mustering stations with unpowered, unique tokens which can be read by a user's personal mobile electronic device. The user's device transmits both mustering station identity and user identification to a remote server, where, upon successful validation, the user is removed from a list of persons to be mustered. The system may be part of a physical access security system for the building, in which single-use digital tokens as well as traditional cards may be used to open the doors. The permissions relating to doors or other physical assets may also be used to grant access to logical assets within the building.

The user's device transmits both door and user identification to a remote server, where the decision is made whether to open the door. If so, the server sends an open door signal using the IP suite of protocols to a processor in a powered door lock, opening the door. Another signal may be used indicate whether access is denied or granted. Multiple personal mobile electronic devices may be configured to operate the same door, and users may control access by others.
