Static or Background
The device stores data which is displayed when the button is pressed. For example, you might want to know what inventory is stored in a location or who has been assigned to this picking cart.
A simple URL call for a pick or put can illuminate a device, causing two lines of custom text to be displayed. It can even play a custom tune. For example, the device might instruct a specific picker to select X number of a specific SKU. Or, it could indicate into which bin the picked inventory should be placed.
As above, a simple URL can be sent to the device, but instead of simply illuminating the device, the device can flash to get someone’s attention.
