This is a barcode scanner holder mounted to the edge of a partition wall. The holder is made of black plastic and is designed to securely cradle the handle of the scanner, keeping it upright and easily accessible. It appears to be attached to the partition with a bracket and screw, allowing it to stay firmly in place. The barcode scanner rests in the holder with its cable hanging downward, ready for quick use in a workspace or point-of-sale environment.
