If using the cards was totally separate from the phone service and other apps it could be interesting. Say it was an app from the credit card company rather than Google Wallet or Iris? I don't care for the fact that phone info might show. Give some merchants phone numbers or any info and bang! you have SPAM. Aside from verifying payment received, they have no business contacting you.
Right now, stores that want addresses and zip codes to help them market either get told where to go, or given wrong info. The CC company has the right address.
