1. A system for impeding reception of confidential information, comprising:
- a point-of-sale transceiver configured to receive a confidential information transmitted by a mobile device incorporating an electronic wallet; and
a signal generator in communication with the point-of-sale transceiver and configured to broadcast a jamming signal substantially concurrent with the point-of-sale transceiver receiving the confidential information, wherein the signal generator is configured to broadcast the jamming signal according to a directional radiation pattern, wherein the radiation pattern substantially directs a null of the directional radiation pattern towards the point-of-sale transceiver.

10. A method of impeding reception of confidential information, comprising:
-
producing a jamming signal; broadcasting the jamming signal from a point-of-sale device; and receiving confidential information at the point-of-sale device, wherein the jamming signal is broadcast substantially concurrently with the reception of the confidential information and wherein the confidential information is received from a portable electronic device containing an electronic wallet, wherein broadcasting the jamming signal produces a directional radiation pattern having at least one null direction and wherein broadcasting includes directing one null direction of the directional radiation pattern towards the point-of-sale device. - View Dependent Claims (11, 12, 13, 14)

15. A method of impeding reception of confidential information, comprising:
-
producing a jamming signal; broadcasting the jamming signal from a point-of-sale device; and receiving confidential information at the point-of-sale device, wherein the jamming signal is broadcast substantially concurrently with the reception of the confidential information and wherein the confidential information is received from a portable electronic device containing an electronic wallet, wherein broadcasting the jamming signal occurs substantially continuously while the point-of-sale device is ready for service.

16. A method of impeding reception of confidential information, comprising:
-
producing a jamming signal; broadcasting the jamming signal from a point-of-sale device; and receiving confidential information at the point-of-sale device, wherein the jamming signal is broadcast substantially concurrently with the reception of the confidential information and wherein the confidential information is received from a portable electronic device containing an electronic wallet, wherein broadcasting the jamming signal is substantially turned off when the point-of-sale device is not communicating with the portable electronic device.

17. A method of jamming reception of confidential information, comprising:
-
exchanging handshaking signals between a portable electronic device and a point-of-sale transceiver, wherein the portable electronic device contains an electronic wallet; the portable electronic device transmitting a preamble sequence during a first time interval; the point-of-sale transceiver transmitting a cancelling preamble sequence during the first time interval, wherein the cancelling preamble sequence is operable to substantially attenuate the preamble sequence; and the portable electronic device transmitting a confidential information during a second time interval, wherein the second time interval follows the first time interval in time. - View Dependent Claims (18, 19, 20)
