Bar codes are read by a bar code reader. A low-powered laser in a bar code scanner emits a beam that crosses the bar code, generating a series of light and dark reflected flashes.

These are compared to the codes in the store's computer to identify the item, look up the price, and add it to the register bill. Modern self-service check-outs have lasers that scan in two perpendicular directions, to read barcodes in any position relative to the scanner.
