a processor operably coupled with the primary electronic display, the secondary electronic display, and the scanner engine, wherein the processor is configured to execute a display control module that ensures the secondary electronic display is in an OFF state when the scanner engine is in an ON state.

2. The device according to claim 1 , wherein the display control module further causes the secondary electronic display to be in an OFF state when the primary electronic display is in an unlocked or ON state, and causes the secondary electronic display to be in an ON state when the primary electronic display is in a locked or OFF state.

3. The device according to claim 1 , wherein the display control module is further configured to:

receive messages from one or more applications being executed by the mobile electronic device; and

display a notification of a received message on the secondary electronic display.

4. The device according to claim 3 , wherein the display control module is further configured to queue messages for display on the secondary electronic display.

5. The electronic device according to claim 4 , wherein the display control module is further configured to enable a user to scroll through the messages in response to the user activating one or more user-interface elements of the mobile electronic device.

6. The device according to claim 2 , wherein the display control module is further configured to detect a condition from an onboard sensor of the mobile electric device, and cause the secondary electronic display to be enabled and the scanner engine to be disabled in response to detecting the condition.

7. The device according to claim 1 , further comprising a housing configured to support the primary electronic display to form at least a portion of a front face and both the scanner engine and the secondary electronic display to form at least a portion of a top face of the mobile electronic device.

8. The device according to claim 1 , wherein the secondary electronic display is touch sensitive, and wherein in response to a user touching the secondary electronic display, the scanner engine being triggered to perform a machine-readable indicia scan.

9. A method, comprising:

operating a secondary electronic display of a mobile device that includes a scanner engine and a primary electronic display;

operating the scanner engine; and

in response to the scanner engine being transitioned from an OFF state to an ON state, causing the secondary electronic display to be in an OFF state.

10. The method according to claim 9 , further comprising enabling the secondary electronic display to be in an ON state and the scanner engine to be in an OFF state when the primary electronic display is in a locked or an OFF state, and causing the secondary electronic display to be an OFF state and the scanner engine to be in an ON state when the primary electronic display is in an ON or unlocked state.

11. The method according to claim 10 , further comprising:

receiving messages from one or more applications being executed by the mobile electric device; and

displaying a notification of a received message on the secondary electronic display.

12. The method according to claim 11 , further comprising queuing messages for display on the secondary electronic display.

13. The method according to claim 12 , further comprising enabling a user to scroll through the messages in response to the user activating one or more user-interface elements of the mobile electronic device.

14. The method according to claim 9 , further comprising:

detecting a condition from an onboard sensor of the mobile electric device; and

causing the secondary electronic display to be enabled and the scanner engine in response to detecting the condition.

15. The method according to claim 9 , further comprising, in response to a user touching the secondary electronic display, triggered the scanner engine to perform a scan of a machine-readable indicia.

16. A method, comprising:

operating a scanner engine located on a top face of a mobile electronic device that includes a primary electronic display located on a front face of the mobile electronic device that is perpendicular to the top face;

operating a secondary electronic display positioned on the top face adjacent to the scanner engine; and

in response to the primary electronic display being unlocked or transitioned to an ON state, causing the secondary electronic display to be in an OFF state and the scanner engine to be in an ON state.

17. The method according to claim 16 , further comprising in response to the primary electronic display being unlocked or transitioned to an OFF state, causing the scanner engine to being in an OFF state and the secondary electronic display to be in an ON state.

18. The device according to claim 7 , further comprising a cover disposed on the top face that is configured to be physically moved cover or uncover the scanner engine, and wherein the display control module automatically causes the secondary electronic display to be in an OFF state, the primary electronic display to be in an ON state, and the scanner engine to be in an ON state responsive to the cover being moved to uncover the scanner engine.

19. The device according to claim 2 , wherein the scanner engine includes an illumination device that is enabled when the scanner engine transitioning is an ON state, and disabled when the scanner engine transitioning is an OFF state.

20. The device according to claim 18 , wherein the illumination device is a laser element.
