Abstract
An optical scanning system for reading indicia of differing light reflectivity has an optical scan module including a light emitter for emitting light onto the indicia and a light detector for detecting the reflection of light from the indicia. The scan module is adapted to be mounted on at least one finger of a user. A first peripheral module has a receiver for receiving a first signal corresponding to the detected reflection of light from the optical scan module. The first peripheral module is adapted to be mounted on an arm or wrist of the user. A second peripheral module includes a receiver for receiving a second signal corresponding to the first signal from the first peripheral module by radio frequency transmission. According to other aspects of the invention, the light detector is located in a housing separate and apart from the optical scan module.
