A method, a system and a product for managing information uses of an absolute position-coding pattern formed of marks positioned on one or more products. The coordinates of the marks define an imaginary surface, which includes all marks which the absolute position-coding pattern has the capacity to code. The imaginary surface is divided into at least two regions, the coordinates of which can be separated from each other. The information is generated by passing a sensor device over the marks on the product and reading the absolute coordinates of the position of the sensor device. Reading of coordinates from the first region results in a information management function of the sensor device, such as a send function, and reading of coordinates from the second region forms message information.
