![]() ![]() Once an image is captured, the barcode reader uses a decoder algorithm to unlock the data invisible to the naked eye. A barcode’s dark areas absorb light the light areas reflect it to provide a contrasting image. Inside this image, the camera looks for areas of light and dark. Today, a camera "sees" either the complete code or an image that has the code within it. In the barcode’s beginning, a laser or CCD device "saw" a small part of a barcode. Barcode scanners must read barcodes of different shapes, sizes, and conditions. "It’s about being able to read a barcode, decode that pattern, and output data quickly and reliably."Ī: In a two-step process, a barcode scanner captures an image, then "decodes" the barcode. "So that’s what our whole barcode system is about," explains Witney. Giving them additional appeal, CCDs can read barcodes more than an arm’s length away. After seeing how successful the first commercial barcode application was, the original barcode spawned 40+ types (also called symbologies) to tackle all sorts of problems, from tracking medical components to catching expired or recalled food at the point of sale.īarcode scanners have since evolved into camera-based devices that can read sophisticated, data-rich 2D barcodes like QR codes these camera-based scanners belong to a group of devices called "charge-coupled devices" (CCDs). In their early days, barcode scanners were laser-based devices that read 1D barcodes-a good example is the supermarket device that beeps when scanning an item’s UPC. Decoding algorithms are very well-defined lists of instructions that machines and computers use to solve a problem or perform functions. A barcode scanner can read a barcode and put it through an integrated decoder algorithm to access the barcode’s original data. What are the main barcode scanning technologies?Ī: Barcode scanners can be anything from a purpose-built device to a smartphone that reads a barcode, which is an optical pattern encoded with data.The commonly asked questions covered here are: Witney, Code Corp’s London-based solutions architect, and his colleagues have been asked just about everything barcode-related when businesses shop, "spec," and buy barcode scanners. To craft this blog, we consulted Vernon Witney at Code Corporation, which has specialized in barcode scanning hardware and software for 20+ years. Taking these steps will ensure that whatever barcode scanner (also called a barcode reader) you buy is the best tool for the job, making it the best value for you. Being informed enables you to ask sharper questions when shopping and communicate effectively with a buying committee or influential users. To help, we’ve crafted this "barcode basics blog" to familiarize you with these mission-critical dataĬapture devices. Code’s Barcode Readers serve a wide range of industries. This considerable number makes shopping for automatic identification and data collection (AIDC) technology, like barcode scanning software and barcode scanners, a big deal. That’s the estimated value of big data and business analytics in 2021, according to global data specialist, Statista. Barcode FAQs: What you need to know about the not-so-basic barcode
