Cannot output scanned barcode data to HTML fields in Chromium-based web browsers

Last updated July 26th, 2023



In Knox Capture, you may experience issues outputting scanned barcode data to HTML fields in Chromium-based web browsers. This issue affects Android 11 devices and is resolved on Android 12 and higher devices.

  • Android 11

  • Chromium-based browsers, including:

    • Samsung Internet
    • Google Chrome
    • Microsoft Edge


If you are experiencing this issue, there are two resolutions and one workaround for scanning barcode data into HTML fields:

  • Using the Advanced data formatting method
  • Using the Floating Action Button (FAB) method
  • Using another web browser as a workaround

Advanced data formatting method


This method has been tested and confirmed working on the following device models running Android 11 with Knox Capture

  • Samsung Galaxy S21
  • Samsung Galaxy XCover Pro
  • Galaxy Tab Active3

You can resolve this issue by sending a Pause command before you send the barcode data. To do this:

  1. Refer to the procedure for Advanced data formatting and follow steps 1–6. After you tap Add Actions, a list of options opens.
  2. Select Send Pause and tap Add.
  3. Tap Add Actions again, then select Send remaining characters and tap Add.
  4. Verify that the two actions, Send Pause and Send remaining characters, are on the rule screen.
  5. Close the Knox Capture app and perform a test scan in Chrome or Samsung Internet.

Enable the Floating Action Button (FAB)

You can also resolve this issue by using a Floating Action Button (FAB) instead of the hardware key to perform a scan. To enable the FAB in Knox Capture, refer to step 6 in Set camera scan trigger.

Workaround using another web browser

To avoid this issue altogether, you can output your scanned data to a web browser built with a different browser engine, such as Mozilla Firefox.
