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.
