Abstract: Systems of the present invention allow individuals to make and change reservations, check into accommodations, and gain access to their accommodations using their own mobile devices as well as mobile devices provided with the rooms. Room access can be through an entry control system comprising two modules that are mounted to a door and to a proximate wall, or similar fixed surface. One module communicates with an electronically controlled locking mechanism of the door lock, the other module wirelessly receives a room code from the user's mobile device. When the room code is correct, the second module communicates a signal to the first module which unlocks the lock.
