Sensitive and accurately captures 1D and 2D barcodes on labels, paper, mobile phone screens, and computer screens. Plug into a standard USB port to start scanning—no drivers required and no battery needed. Automatically reads barcode information within the valid reading range. Adjustable head design for comfortable use based on height and usage preference. After turning on the scanner, when a barcode is brought into range, the scanner automatically recognizes it. A solid blue light indicates successful scanning.
