A portable electronic device is disclosed The portable electronic device comprises a contactless communication transceiver configured to provide payment information to a point-of-sale terminal, a first input device configured to receive inputs, and a processor The first input device is selected from the group consisting of an accelerometer, a microphone, a camera, and a biometric sensor The processor is configured to activate an electronic wallet based on inputs from at least one of the first input device and the contactless communication transceiver, to access the payment information in the electronic wallet, and to provide the payment information to the contactless communication transceiver

Method for launching an electronic wallet

A method for point-of-sale transactions is disclosed. The method comprises a point-of-sale terminal receiving a confidential information from a portable electronic device over a contactless communication link, the confidential information being used by the point-of-sale terminal to complete the transaction. The method also includes substantially blocking access to the contactless communication link beyond the area adjacent to the point-of-sale terminal to reduce eavesdropping on the confidential information.

Method and system for blocking confidential information at a point-of-sale reader from eavesdropping

A method of preventing identity theft is provided. The method comprises reading confidential information from a mobile terminal that is not in communication with the public wireless communication network and determining if the mobile terminal has been reported lost. When the mobile terminal is determined to have been reported lost, the release of the confidential information by the mobile terminal is disabled.

Control of secure elements through point-of-sale device

A method of pointing an antenna at a transmitter comprising the steps of: (a) varying the azimuth of the antenna dish a predetermined number of degrees in a first direction from a predetermined azimuth angle; (b) measuring a first signal strength of an incoming signal received by the antenna dish; (c) varying the azimuth of the antenna dish the same predetermined number of degrees in a second direction from the predetermined azimuth angle, where the second direction is opposite to the first direction; (d) measuring a second signal strength of the incoming signal received by the antenna dish; and (e) comparing the first signal strength to the second signal strength, and if the first signal strength substantially equals the second signal strength, the current predetermined azimuth angle represents the optimal angle of azimuth for the antenna dish. However, if the first signal strength does not substantially equal the second signal strength, the process further comprises the steps of: (f) adjusting the predetermined azimuth angle, and (g) repeating steps (a)–(e). The same process is then repeated for the elevation adjustment.

Method and apparatus for satellite antenna pointing

A satellite antenna for transmitting and receiving an electromagnetic signal has at least one parabolic reflector, a source arm, and a high-power amplifier, in which antenna the high-power amplifier includes a traveling wave tube on the source arm and a high-voltage power supply off the source arm and adapted to supply power to the tube. A satellite mobile telecommunications station includes such a satellite antenna and a storage structure into which the antenna is folded and in which the high-voltage power supply sits.

Satellite transmission antenna and satellite-based mobile telecommunication station

An improved apparatus and method for pointing a satellite dish to receive signals from a geo-synchronous satellite. An aperture cover is used to partially block electromagnetic radiation provide to a feed horn and power and/or signal quality measurements are taken with the aperture cover covering various portions of the feed horn opening. Based on these power and/or signal quality measurements, it is determined in what direction and what angle in that direction the satellite dish must be re-oriented to achieve optimal signal strength from a geo-synchronous satellite or other fixed position microwave source.
