The Smart Tags application explained
The Smart Tags app takes bits of information and transforms the info into a smart tag that you can share as a QR Code. Info can include text, websites and other URIs, phone numbers, and email addresses. The Smart Tags app allows you to store the smart tags that you receive and use them or pass them on later.
Instead of handing out business cards, try creating a smart tag that contains your contact information so that with just a click, recipients can call, text, or send you an email.
