The origin of the barcode is a story of frustration turned into inspiration. In 1948, a Philadelphia grocery store executive pleaded with officials at the Drexel Institute of Technology to find a way to speed up checkout lines. Bernard Silver, a graduate student, took up the challenge. Along with his friend Norman Woodland, they filed a patent for a "bullseye" circular pattern of concentric circles. However, the technology of the era—bulky, expensive laser scanners—could not support their vision. It would take another two decades for lasers to become cheap enough and for the Universal Product Code (UPC) to be standardized. On June 26, 1974, a pack of Wrigley’s chewing gum became the first retail product ever scanned in a supermarket in Troy, Ohio. The silent revolution had begun.

En skanning tar bråkdelen av en sekund, vilket snabbar upp inventeringar och utcheckningsprocesser dramatiskt. streckkodsystem

Dessa består av vertikala streck och är de mest välkända. Along with his friend Norman Woodland, they filed

However, the barcode system is not without its limitations, leading to its quiet evolution. The original linear code can only store a limited amount of data—roughly 20-25 characters. As industries demanded more information (expiration dates, batch numbers, even serial numbers for individual items), the barcode needed an upgrade. This gave rise to two-dimensional (2D) codes, such as the QR code (Quick Response). Unlike its linear ancestor, the 2D code stores data both horizontally and vertically, allowing it to hold hundreds of times more information. It can even include error correction that allows a damaged code to remain readable. Today, hospitals use 2D barcodes on patient wristbands to prevent medication errors, and airlines use them on boarding passes to speed up boarding.

Ett streckkodsystem är en kombination av hårdvara och mjukvara som används för att identifiera och spåra objekt digitalt. Systemet består i huvudsak av tre delar:

Det finns två huvudkategorier av koder som används inom industrin idag: 1D-koder (Linjära)
