Barcode Tech -

In an era dominated by radio-frequency identification (RFID) and biometrics, the humble barcode remains the most ubiquitous and cost-effective method for identifying and tracking objects. A barcode is a machine-readable representation of data that conveys information by varying the widths and spacings of parallel lines (linear barcodes) or patterns of dots, rectangles, and hexagons (2D barcodes). The primary advantage of barcode technology lies in its balance of low implementation cost, high accuracy (error rates as low as 1 in several million characters), and speed (capturing data in milliseconds). This paper dissects the technical architecture, operational standards, and evolving ecosystem of barcode technology.
