Using barcodes are very beneficial for organizations. There might also be thousands of different products in such supermarkets or warehouses. Manually counting each product in a big store or warehouse is impossible. While pitched as a benefit to the consumer, this practice is considered to be potentially dangerous by privacy advocates.Barcodes have become a vital element in inventory and stock management in stores, supermarkets, godowns, and even factories.

This technology also enables the profiling of individual consumers, typically through a voluntary registration of discount cards.

Items may be repriced on the shelf to reflect both sale prices and price increases.

Historical data can be used to predict seasonal fluctuations very accurately.

The effects of merchandising changes can be monitored, allowing fast-moving, more profitable items to occupy the best space.

Slow-selling items can be identified, preventing inventory build-up.

Fast-selling items can be identified quickly and automatically reordered.

Later applications software became available for devices that could read images, such as smartphones with cameras. Later two-dimensional (2D) codes were developed, using rectangles, dots, hexagons and other geometric patterns in two dimensions, usually called barcodes although they do not use bars as such.īarcodes originally were scanned by special optical scanners called barcode readers. Originally barcodes systematically represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D).

Optimal when the barcode size needs to be minimized.
