Abstract

The reading method includes the step of successively performing a first and at least a second scan of an optical code along a first and, respectively, second scanning line parallel to each other. More specifically, the first and second scan of the optical code are performed by generating a first and a second laser light ray movable respectively in a first and second scanning plane distinct from and intersecting each other.
