Scanner Simulator is a Chrome add-on designed to simulate barcode scanning within the active tab. This free tool allows users to replicate the functionality of a barcode reader, enhancing productivity for tasks requiring barcode input. Users can input characters through a prompt, which triggers 'onKeyDown' events, mimicking the behavior of an actual scanning device.

This add-on is particularly useful for developers and testers who need to validate barcode scanning processes or for anyone who frequently works with barcode data. By providing a straightforward interface and seamless integration with the Chrome browser, Scanner Simulator streamlines the workflow of managing barcode information effectively.
