Bar Code Reader

In simple terms, a barcode is a set of specific lines that represent a series of numbers. Each item sold in the store has its own unique product code. By scanning this code with a Barcode Reader, the item can be identified in the store’s electronic point-of-sale (EPOS) inventory system. The barcode was first patented in 1951 by American inventors Norman Joseph Woodland and Bernard Silver. Barcodes are based on Morse code, originally known as “bolls”. Although they initially attracted little commercial interest, barcodes became popular in the 1970s when supermarket chains began using them in their checkout systems. While there are many different types of barcodes, most products use a Universal Product Code (UPC). The Universal Product Code (UPC) is the most common barcode and consists of lines representing numbers with a product code printed underneath.

What is a Barcode Reader

Simply put, a Barcode Reader (also known as a barcode scanner) is an electronic device that scans, decodes, and captures the information represented by a barcode. Most barcodes will also contain a product code in case employees need to actually enter the number. While UPC is the most basic barcode, there are many different types. These include barcodes that contain lines that can represent symbols and numbers as well as numbers. The most common variant of the UPC is the 2D barcode. 2D barcodes can contain more information than traditional UPC codes and are most commonly found on self-printing postage stamps. Another great example of a 2D barcode is the QR code that can be found on restaurant menus and check-in labels since the start of the COVID-19 pandemic. As useful as barcodes are, they’re really useless if we can’t read them. Fortunately, the technology we need to decode them is readily available in the form of barcode readers. Typically, barcode readers include:

Everyone who has ever bought something in a store has at some point interacted with a barcode scanner. There are many different types of barcode readers, depending on the industry and business needs. While they work the same way, they are physically very different. These include:
