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 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.
