Sensor array system selectively configurable as a fingerprint sensor or data entry device
First Claim
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.

Abstract
Devices, systems, and methods facilitate enrollment of authenticating biometric data for authenticating an authorized user via a biometric sensor. Included devices transmit power to a sensor-enabled device that does not have an independent power source without transmitting data to or from the device. Data input devices coupled to the biometric sensor enable user input of non-biometric data, such as an activation code, via the biometric sensor. For biometric sensors comprising fingerprint sensors, finger guides position a finger to contact the sensor at a desired orientation. Systems and methods allow for enrollment of one or more authenticating biometric data templates with or without requiring input of non-biometric authentication data, such as an activation code.

14. A method for enrolling a fingerprint template on a smart card having a fingerprint sensor, the method comprising:
-
inserting an end of the smart card into a receptacle; removably attaching a finger guide to the smart card, wherein the finger guide comprises two or more channels, and wherein each channel is configured to position a finger placed thereon to contact the fingerprint sensor at a different orientation; transmitting power to the smart card from a power element supported on the receptacle without transmitting data to or from the smart card; causing the fingerprint sensor to operate in an enrollment mode; while the fingerprint sensor is operating in enrollment mode, generating two or more fingerprint images with the fingerprint sensor by instructing a user to contact the fingerprint sensor by placing the same finger on each of the two or more channels of the finger guide to position the finger placed thereon in a different orientation with respect to the fingerprint sensor; deriving at least one verification template of fingerprint data from the two or more fingerprint images; storing the verification template; and after storing the verification template, terminating enrollment mode in the fingerprint sensor. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
