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. ## Claims ### Claim 1 A device to facilitate enrollment of a verification template of biometric data in a biometric sensor-enabled smart card, the device comprising: a non-data transmitting power source comprising a receptacle configured to be removably coupled to the smart card and a power element supported on the receptacle that provides power to a smart card to which the receptacle is coupled;
