BARCODE
A barcode is a machine-readable labelling system consisting of parallel bars of different widths that encode data. These codes can be scanned using optical readers, such as barcode scanners (e.g. Trigger Handle IS-TH1), and the data can then be processed electronically.
Types:
1D codes: Classic barcodes (e.g. EAN, Code 128).
2D codes: Area codes, such as QR codes or Data Matrix.
Applications:
Product identification, warehouse management, stock taking and automatic data collection in retail, logistics and industry.
