Export a contact as a vCard on iCloud.com
You can export a virtual card, called a vCard. vCards contain contact information for one or more contacts.
You can attach vCards to email messages, making it easy to share them with others.
In Contacts on iCloud.com, select a contact in the contacts list.
Tap the Action pop-up menu in the sidebar, then choose Export vCard.
Tip: You can export all of your contacts as a vCard and use it as a backup. In landscape orientation, make sure the All Contacts group is selected. Tap the Action pop-up menu in the sidebar, choose Select All, then follow the instructions above to export a vCard.
