Patent ID: 6970584

Claim:
An enclosure assembly for a fingerprint sensor, the enclosure assembly comprising: a stationary member including at least two substantially parallel sidewalls, the sidewalls partially defining a cavity in which the fingerprint sensor is disposed; a moveable access piece, which has a surface area larger than the surface area of the fingerprint sensor, the moveable access piece having a conductive portion electrically coupled to ground, wherein the moveable access piece is configured to move relative to the stationary member; a movement apparatus configured to maintain the moveable access piece in a position covering the fingerprint sensor and yet to allow motion of the moveable access piece relative to the stationary member so as to expose the fingerprint sensor; such that the moveable access piece is capable of defining at least two image alignment positions for the finger from which the fingerprint sensor can collect biometric information; a switch configured to electrically couple a power supply to the fingerprint sensor after the moveable access piece exposes at least a portion of the cavity; and an image quality indictor communicatively coupled to the fingerprint sensor, the image quality indictor configured to obtain an image of a fingerprint, evaluate the image quality, and signal whether biometric information collected by the fingerprint sensor is acceptable.
