1. A fingerprint image processing apparatus comprising:
- (a) a means for imaging having a contact surface adapted to receive a finger thereon; and
(b) a drying means mounted on said imaging means in proximity with said contact surface, said drying means adapted for removing moisture from said contact surface and from a finger which is in proximity with said contact surface by directing a flow of air across said contact surface.

Abstract
A finger drying component for use with a finger print image processing apparatus is disclosed. The drying component removes moisture from the finger so that an unsmudged finger print can be imaged. A preferred embodiment involves the use of a forced air dryer to conduct a stream of air across the optical imaging surface.
