4.2 PACKTRACK™
PackTrack™ is a patented operating mode for DATALOGIC Omnidirectional Reading
Stations used to read and correctly assign codes read on parcels when placed in the scanner
Reading Area at the same time.
In fact, in the example below, the codes of two or more consecutive parcels are found at the
same time in the scanner reading area. Therefore the condition occurs where, in the
sequence of the two parcels, the code of the second parcel is read first, just before the code
of the previous parcel. A system without PackTrack™ would assign the code of the second
parcel to the first parcel and viceversa, thus causing a gross error in the sortation.
