Barcode Reader

History

The first barcode scanner was employed and the first product barcoded in 1974.
In 1932 Wallace Flint started a project at the Harvard University Graduate School of Business Administration to better automate customer purchasing. As punch cards were all the rage at the time, the system they envisioned used a catalog of items with corresponding punch cards for each one. The customer would hand the cards to a clerk who would load them into a reader. The item would then be found and retrieved from a fully automated warehouse.An itemized bill was automatically produced. In spite of its promise, punch card systems were expensive.

1.1. What is Barcode ?

A barcode is an optical machine-readable representation of data, which shows certain data on certain products. Originally, barcodes represented data in the widths (lines) and the spacings of parallel lines, and may be referred to as linear or 1D (1 dimensional) barcodes or symbologies. They also come in patterns of squares, dots, hexagons and other geometric patterns within images termed 2D (2 dimensional) matrix codes or symbologies. Although 2D systems use symbols other than bars, they are generally referred to as barcodes as well. Barcodes can be read by optical scanners called barcode readers, or scanned from an image by special software.
