Abstract: A system for controlling operation of an electric device includes the electric device, at least one contactless sensor module connected to the electric device, and a wearable item equipped with a sensor-readable tag configured for contactless interaction with the contactless sensor of the electric device. The tag is configured for movement with the wearable item into a plurality of different positions relative to the contactless sensor, and the contactless sensor is configured to sense different sensor readings in response to movement of the tag into the plurality of different positions. The electric device is configured to enter a first operating mode in response to the contactless sensor sensing a first position of the tag, and to enter a second operating mode in response to the contactless sensor sensing a second position of the tag.
