As noted by the blog Ata Distance, Apple Pay support for the Octopus card was introduced today and is still rolling out to all users in Hong Kong. Express Transit mode is supported, allowing for tap-and-go payment without needing to authenticate the iPhone or Apple Watch with Face ID, Touch ID, or a passcode.
To add a card to the Wallet app, tap on the plus sign in the top-right corner and follow the instructions.
2019 was a big year for Apple Pay with Express Transit mode, with major cities like London and New York City rolling out support. The feature is available in several other cities, too, including Chicago, Portland, Sydney, and Beijing.
