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.
