Abstract
A system and method for enabling secure short-range communication. A close proximity transmitter is used that is designed with a relatively poor radiator as compared to a conventional transmitter supporting conventional transmissions such as mobile phone communications, Wi-Fi, or Bluetooth communication. The close-proximity transmitter and the conventional transmitter are selectively activated based on a communication mode.
Claims18
A wireless device, comprising:
- a first antenna that is designed to enable communication from said wireless device to a first device;
- a second antenna being designed for improved performance when in close proximity to a complementary antenna in said second device;
- and
- a switch that enables a change in coupling between a transmission module and one of said first and said second antennas, wherein said second antenna facilitates a communication between said wireless device and said second device of confidential information that facilitates communication between said wireless device and said first device using said first antenna.
