A USB barcode scanner is a device that reads barcodes and transmits the decoded data to a computer via a USB connection. These scanners are widely used in retail, inventory management, logistics, and healthcare. Here’s a quick guide to help you understand and choose one: Types of USB Barcode Scanners 1. 1D Scanners • Reads traditional linear barcodes (e.g., UPC, EAN). • Common in retail and POS systems. 2. 2D Scanners • Reads QR codes, Data Matrix, PDF417, and 1D barcodes. • Used in logistics, healthcare, and mobile payments. 3. Laser vs. Imaging • Laser: Good for l .Imaging (CCD/CMOS): Better for damaged or poorly printed codes, supports 2D barcodes. Plug & Play • Most USB barcode scanners are HID (Human Interface Device) compliant. • Plug into a USB port and act like a keyboard (no driver installation needed).
