What data do these cards allow stores to​ gather, and why would they want that​ data?

Answer 1

Stores usually ask customers for a mailing address and email in order to gather information from both the records made by the use of such a mailing address and the email, that is the contacts linked to the mail address and the online tracking recorded with that email.

This is an exception for the customers warned and worried about these aspects of mailing and email tracking history available on tracking software, such as the ones with mailing address and email restricted privacy policies choices.
