The vCard Action allows you to create a vCard for your contact information to enable users to easily save it to their contact library.
By adding your app's link to the vCard, you also give users the option of saving your app to their contacts. Some may prefer to keep it in their contacts as opposed to saving it as an icon to their home screen.
To create a vCard Action, begin by selecting [New Action] from the "Editing" page and then choosing Action Type "vCard."
Then enter the elements of your contact information including name, company, phone numbers, email addresses, websites, address, notes, image, and of course, the link to your app, because it will always have your current information.
