A biometric system comprises an identity proving system with a non-volatile memory for storing biometric verification data for a biometric feature of an individual. The biometric system also includes a first body coupled communication interface configured to transmit the biometric verification data via body coupled communication along or through the body of the individual to a second body coupled communication interface. The biometric system further includes an identity verification system comprising a biometric reader configured to measure the biometric feature of the individual to obtain biometric data. The second body coupled communication interface is configured to receive the biometric verification data via the body coupled communication along or through the body of the individual. The biometric reader is arranged so that the second body coupled communication interface is in contact or close proximity to the individual during measurement of the biometric feature by the biometric reader to allow the receiving, and a biometric data verifier configured to verify the obtained biometric data against the biometric verification data.
