1. A system for enrolling a verification template of fingerprint data in a fingerprint-enabled smart card, the system comprising:

  • a non-data-transmitting power source configured to be coupled to the smart card to transmit power to the smart card without transmitting data to or from the smart card, wherein the non-data-transmitting power source comprises a receptacle configured to receive an end of the smart card removably inserted into the receptacle and a power element supported on the receptacle;

    a fingerprint sensor comprising one or more sensor elements and associated circuitry for controlling operation of the one or more sensor elements and for processing signals from the one or more sensor elements,wherein the fingerprint sensor is configured to be installed in the smart card whereby power is transmitted to the fingerprint sensor when the non-data-transmitting power source is coupled to the smart card,wherein the fingerprint sensor is configured to operate in an enrollment mode when power is transmitted to the fingerprint sensor by the non-data-transmitting power source, andwherein, when operating in the enrollment mode, the fingerprint sensor is configured to derive and store a verification template of fingerprint data from fingerprint data generated by the one or more sensor elements; and

    a finger guide that is removably attachable to the smart card and comprises two or more channels, wherein each channel is configured to position a finger placed thereon to contact the fingerprint sensor at a different orientation.
