Hand-wearable coded data reader
First Claim
1. A reading device for reading an interface surface provided on a product item, the interface surface having disposed thereon coded data indicative of an identity of the product item and of a plurality of reference points, each reference point corresponding to a respective location on the interface surface, the reading device including:
- (a) a housing for mounting on at least one finger of the user in use, the housing including an aperture;
(b) a radiation source for illuminating the interface surface of the product item;
(c) a sensor provided in the housing for sensing at least some of the coded data through the aperture when the product item is positioned substantially in contact with the housing; and
(d) a processor for determining, using at least some of the sensed coded data, product identity data indicative of the identity of the product item and position data representing the position of a sensed reference point on the interface surface.
