Switching between multiple coupling modes
First Claim
1. A device for transmitting in multiple coupling modes, comprising:
- a transmission module,at least one periphery module,and a first antenna for a first coupling mode of the multiple coupling modes and a second antenna for a second coupling mode of the multiple coupling modes wherein switching between the first coupling mode and the second coupling mode is conducted between at least polling and listening phases of the first coupling mode and the second coupling mode, wherein a time of polling in said second coupling mode is determined based on a number of a plurality of technologies polled in said first coupling mode, wherein a search for information in said second coupling mode is initiated based on an action associated with said first coupling mode; and
transmitting, through said first coupling mode, said information obtained in said second coupling mode.

Abstract
A device for transmitting in multiple coupling modes has a transmission module (11), at least one periphery module (18), and an antenna (16, 17) for each of the multiple coupling modes. Further, in a method of switching between multiple coupling modes, switching is conducted between at least polling and listening phases of first and second coupling modes. The device and the method enable a seamless switching between e.g. a near field communication and a body coupled communication. Such a coupling or switching is particularly useful for performing secure transactions whereby through body coupled communication a body-worn tag is interrogated which provides a secure code for a transaction initiated through near field communication with a transaction terminal.
