Barcode reading applications are critical to:
▪ Prevent or correct label and shipping errors
▪ Drive up efficiency and throughput
▪ Lower maintenance and overhead costs
▪ Avoid disruption in supply chain
▪ Brand integrity
The need for barcode technology

▪ Barcode Types
▪ 1D
▪ 2D
▪ 3 main reasons for barcodes:
▪ Traceability
▪ Universally understood
▪ Low cost
Main types of barcodes

Laser-based barcode scanning
Light Detector SignalBarcode Digitized Signal

▪ Hard to scan barcodes
▪ Poorly printed
▪ Defective/damaged
▪ Low contrast
▪ Specular reflections
▪ Unidirectional scanning
▪ No omnidirectional (360°) or at leastorthogonal (0° and 90°) reading
▪ Mounting and positioning constraints
▪ Moving parts are subject to failure
▪ No feedback for failed reads
▪ Cannot read 2D codes

Manufacturers Rely Heavily on Laser-Based Solutions.
Among users of the technology, 77 percent rely solely on laser-based or a combination of laser-based and image-based barcode solutions. Only 14 percent rely solely on image-based solutions.

▪ Low-volume Distribution Center Assumptions*
Impact of higher read rates – Case study
Sorter Speed (feet/minute) 400
Average box size (inches) 20
Distance between boxes (inches) 36
Operation (hours/day) 16
Utilization (days/year) 300
Boxes/second 1.43
Boxes/hour 5,148
Maximum boxes/day 82,368
