Just snap a picture of a business card.
Once Pix is loaded up, just place the business card in view of the camera. Snap the picture once the camera detects the outline of the business card.
Now, you can just add them on LinkedIn.
The app automatically collects the information from the business card. Select the "Find on LinkedIn" button to go to their LinkedIn page. Ta-da! Now you're connected on LinkedIn — and, perhaps, one step closer to getting a new job or client.
