Barcode Scanners

A barcode scanner is an electronic device that utilizes optical imaging or laser technology to read various encoded symbols, supporting multiple code formats including 1D barcodes, 2D matrix codes, and QR codes. Its working principle involves illuminating the barcode surface with a light source, capturing the reflected light signal via a photosensitive sensor, and then converting it into digital data through a decoding chip. These devices are primarily categorized by scanning technology into laser scanners and image sensor scanners; by connectivity into USB wired, Bluetooth wireless, and 2.4G RF models; and by usage scenario into various forms ranging from handheld portable units to industrial fixed-mount installations. They are widely used in applications such as retail point-of-sale (POS) systems, warehouse and logistics inventory management, library cataloging, and manufacturing process tracking, significantly enhancing data collection efficiency and accuracy across supply chain management, asset inventory, and goods circulation. Key user groups include retail cashiers, warehouse staff, logistics sorting operators, librarians, and industrial field data collection personnel, with critical applications also found in specialized fields such as medical device management and ticketing systems.
