POWER SOURCE FOR BIOMETRIC ENROLLMENT WITH STATUS INDICATORS

Devices, systems, and methods facilitate enrollment of authenticating biometric data for authenticating an authorized user via a biometric sensor. In one aspect, power is transmitted to a smart card from a power source removably coupled to the smart card, the power source including a power element that provides power to the fingerprint sensor and a finger guide comprising two or more finger guide channels positioned adjacent to the fingerprint sensor of the smart card when the power source is coupled to the smart card. Each finger guide channel is configured to position a finger placed thereon to contact the fingerprint sensor at a different orientation. During the transmission of power to the smart card, the user is instructed with respect to the placement and removal of the user's finger with respect to each finger guide channel with a status indicator associated with the finger guide channel.
