Abstract
A method comprises steps of sensing a first user action, transmitting a first optical message in response to the first user action, and performing at least one optical code reading step in response to non-receipt of a valid response to the first optical message. An apparatus to perform the aforementioned steps and an article of manufacture to direct the aforementioned steps are disclosed.
Claims17
An optical code reader comprising:
- an emitter;
- a detector;
- an optical head having a first aperture and a second aperture;
- a first waveguide coupling the emitter to the first aperture;
- a second waveguide coupling the detector to the first aperture;
