Network Tokenization (Apple Pay/Google Pay) exchange a token unique to {card, device, merchant}. This token is sent from device, to merchant, to acquirer, to card network, and to issuer without the need to resolve token to PAN in the middle (unlike PCI tokenization most payment gateway provides). AFAIK, three parties that are aware of a purchase history of tokenized cards are: Token Service Provider who provides the token, Token Requester who offer the tokenized service (Apple/Google in this case) and a card issuer. Apple Pay for example, uses First Data as its Token Service Provider. (I'm pretty sure Google Pay does as well)
