Portable optical scanning system worn by a user for reading indicia of differing light reflectivity

An optical scanning system for reading indicia of differing light reflectivity comprising:

• a finger mountable optical scan module including a light emitter for emitting light directed at said indicia and a light detector for detecting the reflection of light from said indicia;
• a first peripheral module mountable to an arm or wrist of a user for receiving a first signal corresponding to said detected reflection of light from said optical scan module;
• and
• a second peripheral module mountable to the user and establishing a wireless communication link with said first module for receiving from said first module a second signal corresponding to said first signal;
• wherein:
• said optical scan module is adapted to be mounted on a single finger;
• said optical scan module has a housing portion for housing said light emitter and light detector and a ring mount portion;
• and
• said housing portion is rotatable connected to said ring mount portion.

• a first peripheral module adapted to be mounted on an arm or wrist of a user and including a receiver for receiving a first signal corresponding to said detected reflection of light from said optical scan module;
• and
• a second peripheral module including a wireless receiver for receiving a second signal, corresponding to said first signal, from said first peripheral module;
• wherein said first signal is an analog signal, said first peripheral module includes a digitizer for converting said first signal to a digitized signal and a decoder means for decoding information contained in said digitized signal and said decoder is automatically activated upon said receiver receiving a signal indicative of said indicia.
