Apple Pay merchant rollout (2014)
Apple launched Apple Pay with iPhone 6, letting buyers tap to pay at stores using a stored card. Within months, major retailers and apps added the option to their checkout flows.
Apple Pay became a standard mobile checkout method in the US and later abroad, with most major card issuers and merchants on board within a few years.
It established the pattern of a device-based wallet arriving at checkout and forcing merchants to support a new payment option to satisfy buyer demand.
Cash App Pay is following the same playbook: a consumer payment method moving from the wallet into merchant checkout, starting US-only and expanding as adoption grows.
