Not only is it unnecessary, but you should object. The entire point of Apple Pay is that it is both very secure and completely anonymous. The retailer doesn't need to know your identity and track your purchases. No information about you is passed to the retailer during an Apple Pay transaction: not your name, not your account number, not the type of card you are using. Nothing. Which is how it should be. The retailer is assured that you are the valid account holder by the fact that Apple Pay can't work without a validated iPhone present, which the user has unlocked with either a security code or a fingerprint. Stolen iPhones are accounted for by the fact that such phones can be easily and instantly disabled or bricked by the user.
