This diagram is a derivative of past article The General Process and Benefits of AIDC Systems, It shows the comprehensive applications and functions of fixed mount barcode scanning systems on production lines, mainly on conveyor belts. There scanners are of various technologies (CMOS, laser, imager and vision). Most scanners send data to host directly using a serial, ethernet or USB connection cables. Some scanners carry in their built-in circuits some intelligence boards to compare scanned numbers and images, and some models carry also input sensors (such as box presence sensor) and output triggers to trigger alarms or control some sorting system. The scanned output usually goes to a host system (PDA, control box, server) to store data (and possibly images) and to process additional more actions.
