Barcode Scanner

Barcode scanners are an electronic device that scans and decodes information from barcode symbols. Barcodes are symbols that represent numbers, letters, and other characters by using vertical lines of varying thickness and spacing. The information contained in a barcode is typically recorded and decoded by these machines using a light source, a lens, and a photosensitive sensor. The barcode is illuminated by the light source, and the sensor picks up reflections from the lines of the barcode. The information is subsequently decoded by barcode scanners and sent to a computer or other processing device. These are available in various models and sizes.
