This ensures seamless integration with a wide range of devices, such as smartphones, tablets, and computers.
    • 2.4G Wireless Connection: In addition to Bluetooth, the scanner also offers a 2.4G wireless connection option. This allows for wireless scanning within a certain range, providing flexibility and mobility in your work environment.

This feature is useful when you need to include additional information or identifiers along with the scanned barcode.
