KembaraXtra-Computer Terms – bar code scanner:
A bar code scanner is an optical input device used to read bar codes and convert the encoded information into digital data that a computer can process. The scanner typically uses a laser beam or imaging sensor to detect the pattern of bars and spaces printed on a label or product packaging.
When the scanner passes over the bar code, it analyzes the reflected light pattern and translates it into corresponding numerical or textual information. This data can then be used for tasks such as product identification, inventory tracking, and point-of-sale transactions. Bar code scanners are commonly used in retail stores, warehouses, hospitals, and logistics operations.
