    摘要: A transponder circuit arrangement including antenna contacts to which an antenna signal can be applied. The antenna signal includes at least one signal in one transmission band of a plurality of transmission bands. The transponder circuit arrangement also includes a detector adapted to detect whether the antenna signal includes a signal in a predetermined transmission band, and a demodulator adapted to demodulate the signal in the predetermined transmission band when the signal has been detected therein, and otherwise to demodulate a signal in another transmission band.

    摘要: A contactless device including an contactless communication interface configured to receive a challenge from a contactless reader and a controller configured to generate an enciphered response using elliptic curve cryptology. Moreover, the enciphered response includes the challenge enciphered with a private key stored in non-volatile memory of the contactless device and data can be integrated as part of the challenge and/or the enciphered response.
