<p>An ergonomic fingerprint acquisition device (20) comprises a housing having first and second exterior surfaces (46 and 54), a platen (30), a light source for irradiating the platen (30) and any digit (32) thereon with light, a light conducting plate (64), and image sensing device (68). The platen (30) is disposed in register with an aperture (48) in the first exterior surface (46). The second exterior surface (54) is displaced from the first exterior surface (46) to provide a grasping surface. The housing has a prehensile shape to permit grasping the first and second exterior surfaces (46 and 54) while the person's digit (32) presses on the platen (30) so that the digit (32) applies even pressure to the platen (30) and a broad print of the digit (32) is acquired. The print may be conveyed to a remote location. In addition, the device may be combined with a data extracting device and perhaps a matching device. The device may be used in a notorization system for authenticating that a transaction to be charged against an account has been authorized by an account holder or in combination with a set-top box for use with a television set.</p> |
