Barcode Technology

Barcodes have been used since the 1970s. Barcodes have advanced the way data is stored, shared and interpreted. Barcodes were originally invented because grocery stores did not have any form of an automated checkout with pricing. Barcodes would prove to be a great organizational tool that more than just grocery stores would be able to take advantage of.

Barcode technology actually took over 30 years to develop since it was such a new technology; there was no real way to read the one-dimensional code without the help of lasers. Soon barcodes could be found at the grocery store, retail stores, and even to help organize books in a library.

Barcodes are usually one or two-dimensional codes that are linear and flat. Different types of barcodes hold a varied amount of data depending on the space it has. Linear barcodes hold far less data than that of 2D barcodes. Although barcodes were mostly used for tracking and moving information from one point to the next, today some barcodes are used for holding more information about businesses, people, events, schools, and hospitals. QR codes are quick response codes capable of holding mass amounts of data that can include websites, contact information, maps, coupons, or other resources. Through the use of smartphones people can scan a QR code off of anything and be able to find out more information.
