| 主权项 | 1. A contactless communication device comprising: an energy antenna configured to receive/transmit from/to a contactless communication partner a first carrier signal having a frequency in the high frequency (HF) range; an energy interface which is coupled to the energy antenna and is configured to activate the contactless communication device and enable data communication between the contactless communication device and the contactless communication partner based on the first carrier signal; a high speed data antenna configured to receive/transmit from/to the contactless communication partner a second carrier signal having a frequency greater than a frequency in the HF range; and a high speed data interface which is coupled to the high speed data antenna and is configured to enable data communication between the contactless communication device and the contactless communication partner subsequent to the enabled data communication by the energy interface and based on the second carrier signal. | ||
