Yes. Or my name/address/phone number. It's essentially a machine-readable address label, the email is just one part of the vCard.

Do you people really not keep a book of stamps in your car? Such inconvenience!

I could overload my pockets carrying around all kinds of special purpose labels and stickers, and track my stock of them so I don't run out....or I could carry a pen.

No, why would I do that?
