Abstract: A token device includes: a transmission interface for receiving power from an external device; a physiological characteristic detecting circuit for detecting user's touch actions and physiological characteristics (i.e., biometric characteristics); a smart card accessing circuit for detecting user's card-placing actions and for accessing an on-card secure chip on a smart card; an on-token secure chip; and a control circuit for generating an user identification data corresponding to the detecting result of the physiological characteristic detecting circuit, for respectively transmitting the user identification data to the on-token secure chip and the on-card secure chip for verifying user's identity. If the user's identity is confirmed by both the on-token secure chip and the on-card secure chip, the control circuit would conduct corresponding key backup operations or key restoration operations between the on-token secure chip and the on-card secure chip.
