I'm not really an Apple user, but can someone here explain to me why Apple Pay would succeed, when the same technology (NFC) already didn't work well with Google Wallet? I remember trying it with my HTC One at a CVS store, and quickly realized that if you use a case on your phone, NFC won't really work.
To elaborate:
1) Ecosystem, Userbase and Partnerships
Though Android has a higher market share than iOS, a lot of that market share is in low-cost smartphones. In terms of top-of-the-line handsets, the iPhone is still king. So, Apple is selling more handsets with NFC than Google is. Apple will very quickly have a large number of users with Apple Pay on their phones, while Google does not. Because of this, the point I'm about to make, more intelligent negotiation, and brand recognition, Apple has already negotiated a set of Apple Pay partnerships with banks and retail chains and has widely publicized these. This will lead to more opportunities for users to use Apple Pay and more uses of it on the whole.
2) Privacy and Security
Google is, to put it quite frankly, a really sketchy company with this kind of thing. Google's revenue model is ad-based, so they make money off of selling user information to advertisers. Because of this business model, in which the real customer for Google is not users but advertisers, they have become completely desensitized to user privacy concerns. In contrast, Apple makes almost all their money off of device sales. Their customer is the user. Therefore, they are more responsive to user privacy concerns, and have recognized that this is a key point on which they can soundly defeat Google.
When Apple introduced Apple Pay, they devoted a significant portion of the time they spent on it talking about privacy. I think people would understandably have worries about putting their credit card or bank account information into a phone and putting an additional third party in the transaction between them and the seller. I think Apple has gone out of their way to address such concerns by stating that they will not store any information about transactions on their servers, instead keeping credit card information stored on the device in a dedicated chip. And, in fact, they've taken things a step further by assigning a device identification number to be used in transactions (along with a unique security code for each transaction) in place of credit card numbers. So beyond just taking steps to make the electronic payment system secure, they have actually made it MORE secure than using your plastic debit/credit card. That's a huge advantage over Google.
