Abstract: The present disclosure provides for a mobile communication device identifier, constituted of: a shielding defining a coverage area, the shielding arranged to attenuate radio signals originating externally of the coverage area to be less than a pre-determined signal strength; an antenna associated within the defined coverage area; a transceiver coupled to the antenna, the transceiver operative to communicate with a mobile station inserted within the defined coverage area utilizing a signal strength greater than the pre-determined signal strength; and a service control unit responsive to the transceiver, the service control unit operative responsive to the communication to output a signal indicative of an authorization to provide a product or service.

Abstract: A system providing enhanced security for device based transactions, constituted of: a server associated with a network address; a first device associated with a user, the first device in communication with the server over a first communication channel responsive to an obtained server network address; a second device associated with the user arranged to obtain the server network address from the first device; and a mobile device server in communication with the second device over a second communication channel, the mobile device server in communication with the server via a third communication channel, the mobile device server arranged to: obtain the server network address from the second device over the second communication channel; obtain the server network address from a trusted source; and authorize to the server over third communication channel a transaction only in the event that the server network addresses are consonant.

Abstract: A method and system for secure payment by using a mobile communication device, which may operate using substantially existing communication protocols, and securely identify the mobile device.
