From AppleInsider's "Apple Pay accounted for 92% of US mobile wallet debit transactions in 2020, study says" posted Tuesday:
Apple Pay dominated the mobile wallet space for debit transactions in 2020, a year of significant sector growth thanks to dramatic changes catalyzed by the COVID-19 pandemic.
Apple's payments service accounted for 92% of all mobile wallet debit transactions in the U.S. last year, according to Pulse, an electronic funds transfer firm and subsidiary of Discover Financial Services that serves more than 4,400 financial institutions nationwide.
Pulse's annual 2021 Debit Issuer Study, conducted by Oliver Wyman, shows about two billion mobile wallet debit transactions were conducted in 2020 using either Apple Pay, Samsung Pay or Google Pay. That figure is up 51% year-over-year, with Apple Pay benefitting most to outperform its two major competitors across every metric, the study says.
Compared to Apple Pay's 92% transaction share, Samsung Pay and Google Pay accounted for 5% and 3% of mobile wallet debit transactions, according to Pulse.
My take: I almost feel sorry for Samsung and Google.
