In accordance with one aspect of the present disclosure, a presentation stand is disclosed for enabling a mobile device to read barcodes in presentation mode. The mobile device may include a camera and a first illumination source. The presentation stand may include a base portion, a cradle portion connected to the base portion, and a shield portion attached to the cradle portion. The cradle portion may be configured to hold the mobile device in a position for reading a barcode. The shield portion may be configured to modify a field of view of the camera and a field of illumination of the first illumination source. The shield portion may include a camera optic system that is at least partially aligned with the camera of the mobile device when the mobile device is held in the cradle portion. The shield portion may include an illumination optic system that is at least partially aligned with the first illumination source of the mobile device when the mobile device is held in the cradle portion.

The camera and the camera optic system may define a barcode reading lens system. The barcode reading lens system may have a system field of view that is different from the field of view of the camera. The illumination optic system and the first illumination source of the mobile device may define an exposure illumination system. The exposure illumination system may emit a system illumination field with a system angular size that is different from an angular size of a first illumination field emitted by the first illumination source.
