There are pen readers, which have no moving parts, just a light source and a photodiode to measure the lines and spaces on the 1D barcode. There are different kinds of barcode scanners, some scanners use lasers, while others use lights or cameras, to capture the barcode image and turn it into an electronic code. 2D barcodes store information both horizontally and vertically, resulting in exponentially larger storage capacity however, an image scanner is required to read 2D barcodes, while a simple barcode scanner can only handle linear codes. The blank space doesn’t send any scanning signal and so it is referred to as a quiet space (or quiet zone).įor many years, 1D barcodes were the standard, and they are still in widespread use today despite their smaller capacity for information (they can only contain about 20-25 characters, though stacking the characters helps to increase that number). A quiet zone is a space to prevent the reader from picking up other information that is not wanted or needed in the barcode scan. These include the 1D, or linear barcode, which appears as an image of parallel lines and spaces (usually a quiet zone). Those digits refer to a particular item, and scanning the numbers and bars pulls up an entry in the database with further information such as the price, how many of this item in stock, a description of the item and possibly a picture for reference.īarcode scanners traditionally read the barcodes most people are familiar with. The scanner then sends that information along to a computer database, either through a wired connection or wirelessly (depending on the model). A barcode scanner is much more than a computer with one dedicated purpose.īarcode scanners record and translate barcodes from the image you recognize into alphanumeric digits. Scanners can read different types of barcodes with a variety of functions, some scanners even have operations that smartphones and mobile computers lack. Most individuals have seen a typical barcode scanner at the supermarket (which is where they got their start), but there are many different kinds of scanners.

Barcodes and dedicated barcode scanners are now an integral part of any high-functioning business that wants to take their organizations efficiency and asset management to the next level. The barcode scanning systems are now being used in a myriad of industries, including medicine, travel, manufacturing, entertainment, law, and many other enterprises you might never expect (including death care). Barcodes have helped retailers pack information, such as pricing and available inventory, onto their wares to move things along at the check-out counter, for decades.
