Seriously The Google Bashers Are Being Hilarious
Let's say I own an Android phone. I want to use Apple Pay. Ooops. I can't. So I have to use Google Wallet. The reverse is true too. Suppose I want to use Google Wallet but have an iPhone. I can't. That is it. That is all. End of story.
1. There is no competition between Apple Pay and Google Wallet because both are ecosystem dependent.
2. There is no reason for any retailer or bank that currently supports Apple Pay to reject Google Wallet. (Unless the entity objects to sharing data with Google, a requirement that Google will abandon if they have to.)
3. Which means that both Google Wallet and Apple Pay will succeed. Even if Apple Pay is used more and is used to buy more expensive items, Google Wallet will have more than enough users and purchasers to be viable. Consider the competing app stores as an example. Apple has THE App Store with $150 billion in revenue in 2014. Apple mobile device owners pay more for apps, developers make more on iOS, iOS has better quality apps, gets apps months - and sometimes more than a year - first, and has more exclusive apps. Good for Apple. But the thing is that the Google Play store had $95 billion in revenue in 2014 (or $5 billion less than the App Store had in 2013). And where the App Store had $50 billion in year-over-year growth (from $100 billion to $150 billion), the Google Play store had $45 billion in year-over-year growth (from $50 billion to $95 billion). Which means that the Google Play store is not going anywhere.
Now maybe your hope was that Apple Pay was going to be the thing that finally drove Android users to abandon their Galaxy Notes, Moto Xs and HTC Ones, causing Android to become unprofitable and collapse. Oh yeah, that and Apple finally adopting phablets (after years of claiming that they never would). Sorry. That was never going to happen. Even with Apple's great fourth quarter resulting in a decline in Android sales, a record number of Android devices were still sold last year because the first 3 quarters were so huge. How huge? Every Android manufacturer but Samsung and Sony had record revenue and profits last year.
Android isn't going anywhere, which means that Google Wallet won't either.
