Advantages
Data-gathering systems such as bar code readers use one-way
communication: a sensor reads information from a device, without any
interaction between the two devices.
Moreover, bar code systems are subject to line-of-sight limitations. As a
result, airborne contaminants such as dust, dirt, oil, and mist, as well as
label damage and objects residing outside the line of sight, result in
inefficient and erroneous results.
The SCS Interactive Identification System overcomes these
restrictions by using state-of-the-art technology. This technology
allows the scanner and tag to conduct ongoing two-way
communications that are not restricted by line-of-sight
constraints.
