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.
