You seem to have a fundamental misunderstanding about the difference between Google Wallet and Apple Pay. Wallet does not need (or even function differently) with the "support" of credit card companies - it is a payment processor unto itself. If you have a Visa, Mastercard, AMEX or Discover logo on your card, it works with Google Wallet.
Put differently, Wallet supports 100% of credit and check cards in the US, whereas Apple supports "many".
Pay, because of the need to generate purchase tokens and "one-time-use" cards, requires integration effort on the side of both Apple and the issuing bank. Pay is not a payment processor, just a gateway.
