Abstract
The method includes a step of generating a magnetic signal with an electromagnetic functional unit, wherein the electromagnetic functional unit is an actuator of a loudspeaker of the device or wherein the electromagnetic functional unit is an electromagnetic resonant circuit connected to the device, wherein the magnetic signal carries the data to be transferred from the device to the other device: Furthermore, the method includes a step of detecting the magnetic signal with an electromagnetic resonant circuit of the other device in order to obtain the data to be transferred from the device to the other device, wherein the magnetic signal is FSK-modulated, wherein a resonance frequency of the electromagnetic resonant circuit of the other device and a carrier frequency of the FSK-modulated magnetic signal are tuned with respect to each other.
