Had a conversation with my girlfriend about Apple Pay the other day. I'll preface by mentioning neither one of us use it, even though it's readily available on our phones.
Conclusion: Women will eventually love it, as they don't have to dig through their purses and hundreds of credit/gift cards to find their preferred card.
Men will be resistant, as it is much easier to pull out a wallet where each and every one of us men have our most preferred payment method in the most convenient and most accessible slot in our wallets/money clips and swipe.
