Since I did a little spotlight on Apple I feel the need to address Google too because I felt like maybe it seems like Google is poo poo in payments (Google Wallet launched in 2011) with Apple entering the arena when in reality their plays are quite different.
Where Apple doesn't do as well:
struggles more on partnering because money is recycled within its own ecosystems
locks merchants out and consumers in. pros and cons here.
biometric ID (touch ID)
obviously, Apple is doing extremely well - their model works! But perhaps their model is not the best suited for making the biggest impact (which may not even be their biggest goal).
Where Google differs:
for merchants, consumers, banks, etc.
very open to sharing and partnering
really good at online data - knows everything about you
data means that their business is centered around ad revenue
understand cohorts of data rather than transaction level
As you can see, Google wins in network effects and enabling.
In getting this it, trades off complete control over its ecosystem that Apple. It can enable a whole slew of companies to grow and form symbiotic partnerships for bank data and fintech applications such as neobanks who want automatic data, analytics, merchant integrations, and Android access. Google ties everything together and closes the loop.
So clearly both Apple and Google are not destined to become banks nor should they.
