Abstract: Described herein is a barcode reading system that comprises a barcode reading enhancement accessory secured to a mobile device. The mobile device comprises a camera. The barcode reading enhancement accessory comprises a user-activated barcode read control and circuitry for generating a barcode read signal on the microphone input connector of the mobile device in response to user activation of the barcode read control. The barcode reading system also comprises a barcode reading application that comprises an image capture and decode function for controlling the camera to capture an image of a barcode within the field of view of the camera and generating decoded data representing data encoded in the barcode in response to the barcode read signal on the microphone input connector.

Abstract: This patent specification describes an attachment for a mobile device. The attachment may have an attachment feature designed to be attached to a mobile device such as a smartphone, tablet, or smartphone/tablet with a camera. The attachment may also include an optics system and/or an illumination system that cooperates with the camera to facilitate the capture of decodable barcodes. The illumination system may include a targeting illumination system that facilitates proper positioning of the article and/or an exposure illumination system that helps illuminate the article during capture. The optics system may include a lens that modifies the depth of field and/or the size of the field of view of the camera, an aperture that helps define the field of view, a filter that prevents light of undesired wavelengths from reaching the camera, and/or a mirror that redirects the camera's optical pathway.
