How Barcode Readers Work

Barcode readers utilize various technologies to read barcodes accurately. The most common type is the laser scanner, which emits a laser beam that reflects off the barcode's surface. The scanner then measures the light intensity variations caused by the alternating black and white spaces, converting the pattern into a digital signal This signal is subsequently decoded, and the corresponding information, such as product details or inventory numbers, is displayed on a screen or stored in a database
