Australia is a terrible example. It has 20m people spread very thinly. What we need is a more densely populated country as an example.
In the UK in 2021 Apple Pay was used by
60% of the population to make a transaction
. That is 42m people using it to make at least one transaction. In 2021 there were
13bn contactless payments made in the UK alone which rough maths gives us 7.8bn Apple Pay transactions in 2021. That is 247 Apple Pay transactions a
second! For the record Google Pay
makes up 33% of the population for contactless payments. Only 7% are conducted by just a bank card tap or other means.
Whilst hardly a monopoly, Apple does have the largest market share of the 2 major players.
