On the mobile app, FieldClock makes use of the device's camera when using any 'scanning' view. Below, you can view the three settings and how to use them.
Auto-focus and text orientation settings are not available on Android devices.
The auto-focus toggle simply turns auto-focus on or off, and is rendered as a small circular graphic as seen below.
Text orientation will reverse the direction of any messages that flash on the screen, such as when an Employee is clocked in. The text orientation setting is rendered as a small horizontal button showing 'ABC', as seen below.
