Where is a bar code reader used?

Answer 1

A barcode reader is a machine that interprets barcodes.

Almost every box has a bar code. A bar code are little lines that run straight up and down. Those bars mean something. A bar code reader reads those bars and will translate the bars to whatever it means. In most stores, the checkout counter people look on boxes for that bar code, then they take a bar code reader and scan that.

A barcode reader is commonly used in retail stores, warehouses, libraries, and hospitals to quickly and accurately scan barcodes on products, inventory, books, or patient wristbands to retrieve information or update records.

Answer 3

A barcode reader scans the barcode with a LASER detecting the alternating light and dark bands and their widths. This pattern is then decoded into a series of digits (or sometimes letters depending on the code).
