The device, while idle, displays static or stand-by information including a hazard icon, barcode and/or QR Code. For example, you might want to show what SKU and quantity is stored in a location or who has been assigned to a picking cart.
A simple URL call for a pick or put can illuminate a device button (or make it flash), with up to five lines of custom text to be displayed. The device can even play a custom tune. Use a barcode of QR Code to identify the pick or put. 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.
