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.

Dopable, fully dense polymer membranes are used to form membranes having selective permeabilities. To improve selectivity, the membranes may be subjected to chemical or electrochemical treatment with electron donors or acceptors to alter the doping level of the polymer membrane, generally in a reversible fashion. This leads to significant changes in gas permeation rates relative to what is observed for the non-doped, fully dense polymers. This change in doping level of the polymer films can be precisely controlled by varying the concentration and nature of chemical dopants used. Desirable changes in permeation rates are achieved by a treatment which comprises a reversal doping of the polymeric material, followed by removal of the dopants (to provide an 'undoped' polymer). Further addition of controlled amounts of at least one dopant species to the undoped polymer by a second, 'redoping' procedure can still more dramatically change the permeability of large species, leading to particularly large separation factors.
