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 one or more contacts in the contacts list.
Click the Action pop-up menu in the sidebar, then choose Export vCard.
If you select multiple contacts, Contacts exports a single vCard containing all of them.
Tip: You can export all of your contacts as a vCard and use it as a backup.
