With the newest Google Now update, Google built in a new Voice Action that allows you to scan barcodes with your camera. All you have to say is, â€œScan barcodeâ€ after hitting the voice search button. But if the voice search button isnâ€™t handy or you donâ€™t want to speak out loud to your phone, you can access it another way.
If you open Google Now, scroll to the bottom and hit the 3-dotted menu button in the right corner. As long as you have updated your Google Now, you should see a new option that says â€œSearch with camera.â€ Tap that, and find something to search for with your camera.
So far, Iâ€™ve had good luck snapping photos of text, but logos or objects, not so much. Give it a shot!
