A barcode is a machine-readable representation of data in a visual form, typically consisting of parallel lines or rectangles arranged in a specific pattern. Barcodes are used for automatic identification and tracking of products, assets, and documents in various industries such as retail, manufacturing, logistics, and healthcare. They encode data such as product codes, serial numbers, or other information using patterns that can be quickly scanned and decoded by barcode scanners or imaging devices. Common types of barcodes include UPC (Universal Product Code), EAN (European Article Number), Code 39, Code 128, and QR codes. Barcodes streamline processes, improve accuracy, and provide real-time visibility into inventory and assets.
