A barcode reading enhancement system for a mobile device is described. The barcode reading enhancement system may include an accessory. The accessory may be securable to the mobile device and include a one-way mirror. A first side of the one-way mirror may fold a camera field of view of a camera of the mobile device in a direction away from a top end of the mobile device. The accessory may also include a target-generating structure that projects a targeting pattern through a second side of the one-way mirror into a center of the folded camera field of view. The targeting pattern may assist a user of the barcode reading enhancement system in placing a barcode in the center of the folded camera field of view and thereby improve the quality of barcode images captured by the camera of the mobile device.
