Barcode system



A barcode system is a network of hardware and software, consisting mainly of mobile computers, printers, handheld scanners, infrastructure, and supporting software. Barcode systems are used to automate data collection when manual recording is neither timely nor cost effective. Bar code systems are not radio frequency identification (RFID) systems, although companies that provide bar codes often provide RFID hardware and many companies use both technologies as part of management systems more resources.

In 1948, Bernard Silver was a graduate student at the Drexel Institute of Technology in Philadelphia. A store owner in the local food chain made a request to the Drexel Institute requesting research on a method of automatically reading product information when ordering. Silver has joined another graduate student, Norman Joseph Woodland, to find a solution. Woodland’s first idea was to use ink sensitive to ultraviolet light. The team built a functional prototype but decided that the system was too volatile and expensive. They went back to the drawing board. On October 20, 1949, Woodland and Silver filed their patent application for the “Classifying Apparatus and Method”, describing their invention as “article classification … through identification models”. The first commercially successful bar code reading system was patented in November 1969 by John F. Keidel for General Atronics Corp. It was quickly realized that there should be a set of industry standards. In 1970, the Universal Identification Code for Groceries was drafted by a company called Logicon Inc. The first company to produce barcode equipment for retail (using UGPIC) was the American company Monarch Marking in 1970 and for industrial use, the British company Plessey Telecommunications was also the first in 1970. The UGPIC became the UPC symbol set or Universal Product Code, which is still used in the United States. George J. Laurer is considered the inventor of U.P.C. or Uniform Product Code, invented in 1973. In June 1974, the first U.P.C. The scanner was installed in a Marsh supermarket in Troy, Ohio. The first product to have a barcode included was a Wrigley’s Gum package.

There is a wide range of hardware that is manufactured today for use in bar code systems. The most well-known brand of handheld scanners and mobile computers is Symbol, which is now a division of Motorola. Other manufacturers include Intermec, HHP (Hand Held products), Microscan Systems, Unitech, Metrologic, PSC and PANMOBIL.

Although there is a range of hardware on the market, the software is more difficult to find from hardware manufacturers. Some inventory management software, ERP, MRP, and others have built-in support for barcode scanning, and some even allow the software to run directly on a laptop. In addition to full-featured management software, there are several software development kits available on the market that allow the developer to easily create custom mobile interfaces and manage the connection to the database. One of these software is RFgen else is PeopleVox. Then, it is always possible to develop a custom software solution, using a language such as C ++, C #, Java, Visual Basic.NET and many others. Often, the development of a personalized interface using software such as RFgen or the development of new custom software is the most efficient method since it allows the individual to have a solution adapted to his specific needs .

A typical barcode system consists of a wired or wireless infrastructure that connects a number of mobile computers, portable scanners, and printers to one or more databases that store and analyze data collected by the organization. system. At some level, there must be software to manage the system. The software can be as simple as a code that manages the connection between the hardware and the database, or as complex as an ERP, MRP, or other inventory management software.
