Barcode-reading system having circuitry for generating a barcode read signal on a microphone input connector of a mobile device
First Claim
1. A barcode reading system for a mobile device, the mobile device comprising a camera for capturing an image of a field of view, a microphone input connector embodied in an audio jack, a memory and a processor for executing an operating system and applications stored in the memory, the barcode reading system comprising:
- a barcode reading enhancement accessory secured to the mobile device, the barcode reading enhancement accessory comprising 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, wherein the circuitry comprises a magnet and a conductor, and wherein the user activation of the barcode read control moves the magnet with respect to the conductor to generate or modify a potential differential between a microphone contact and a ground contact of the audio jack; and
a barcode reading application stored in the memory and executable by the processor, the barcode reading application including 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.
