Claim:
A system for capturing biometric data, comprising: a non-planar prism comprising a substantially conical portion, a top portion, and a planar portion, the non-planar prism configured to be illuminated by a light source; and a scanning optical system configured to capture image data of a print area of a hand of a person interacting with the substantially conical portion of the non-planar prism, such that the top portion is located between a thumb of the hand and an index finger of the hand, the thumb of the hand interacts with a first side of the substantially conical portion, and the fingers of the hand interact with a second, opposite side of the substantially conical portion during the capture of the image data; wherein the image data represents substantially all of the print area of the hand of the person, while the hand is stationary on the substantially conical portion of the non-planar prism.
