Information on Barcodes Generators & Scanners

Barcode labels are the tags that help both humans and machines to identify any given product. These labels come in several types and resemble the average tags. These labels are differentiated by the type of base material, called stock, that they are printed on. Labels are currently available in all types of materials and come with a variety of adhesive backings. They can also be ordered in several customized shapes and sizes.

Apart from the basic types of barcodes labels, labels can also be categorized into three main forms: aluminum barcode labels, polyester barcode labels, and ceramic barcode labels. The aluminum labels are very durable, usually with an image on the surface that lasts for a long time, even in the harshest of climatic conditions. It can withstand wear and tear, heat, cold, chemicals and abrasion. The polyester barcode label has an image imbedded in the underside of the plastic material. It uses a permanent industrial adhesive bonding and is known for its dependability. However, the last word in durability is the ceramic barcode label. It is made up of a stainless steel base and coated with ceramic. These labels can withstand strong acids or very high temperatures.

Barcode labels can be further subdivided into the following categories: resin-coated paper barcode labels, paper barcode labels, long-range retro-reflective barcode labels, and floor labels. Resin-coated paper barcode labels are the most common labels used in the official work. These labels are created with the help of tough resin coating for durability. Paper barcode labels are very economical and ideal for tracking of documents.

A long-range retro-reflective barcode label is another case in point. These labels are normally hung from a wall or a ceiling. Made of rigid metal or plastic, these labels provide maximum functionality for long-range scanners. Lastly, we have floor labels. These labels are used in industrial floors and are developed using steel and are then coated with urethane. These labels can withstand heavy vehicular traffic.

With barcode labels forming an intrinsic part of the daily human existence, they are finding an increasing utility in the day to day life. Newer forms of labels are being designed by the day.

Norman Woodland, a 27-year-old graduate student at Drexel Institute of Technology in Philadelphia developed the first code system that automatically read product information during checkout. Woodland and his friend Silver were awarded a patent for their application titled Classifying Apparatus and Method on October 7, 1952. Many experts are of the view that the Woodland and Silver bar code was the basis of what would soon become a global phenomenon.

In the beginning, barcodes were developed to store data in the spacing of printed parallel lines. The idea was to help grocery stores speed up the checkout process and keep better track of the inventory. However, the system soon picked up and became a success story.

Barcodes form the basis of identification in almost all types of businesses in the modern world. Barcodes are variously called as Universal Product Codes or UPCs. These are machine-readable codes and come in strips, generally comprising of a series of short black lines of varied thickness. These codes are read by optical scanners called barcode readers or scanned from an image by special software. A laser reader or scanner can translate the barcodes into the corresponding alpha-numeric digits, which are used to uniquely identify a piece of property. Barcodes are used world over to implement Auto ID Data Capture (AIDC) systems that improve the speed and accuracy of computer data entry.

At present, we have codes in several patterns of dots, concentric circles and hidden in images. Barcodes are provided by a body called Uniform Code Council (UCC). A manufacturer has to apply to the UCC for permission to enter the UPC system. An annual fee is charged for the service. In return, the UCC issues the manufacturer a six-digit manufacturer identification number. The manufacturer identification number is part of a standard 12-digit bar code.

Bar coding standards have brought about great precision, technical refinement and uniformity in the way business is conducted in the world. Throughout the world, most of the data entry is done much more quickly. All data is collected in real time. Bar codes have also led to the elimination of manual data entry and retrieval system. The coding has completely streamlined products, making the most effective use of human and physical resources.
