vCard

For easy vCard import from your PC screen to your smartphone, line your camera up until you see yellow handles on each corner.  Then look for and tap the contact banner that appears at the top of your screen.  View and edit if needed before tapping Create New Contact.

If viewing this from your smartphone, simply push and hold the vCard image until you see the prompt for Add to Contacts.  Select this and the contact screen should appear.  View and edit if needed before tapping Create New Contact.

Open the QR Reader app or camera feature on your smartphone - Hold your device over the QR Code so that it's clearly visible within your smartphone's screen.  Your device will either automatically scan the code, or you may need to press a button to capture it.
