Earlier this year, Octopus Cards Ltd. Hong Kong had announced that customers will be able to use their Octopus cards on their iOS devices for transit and retail payment with Apple Pay later this year.
However, the company has now revealed that Apple Pay support has been delayed until later in 2020 (via MacRumors).
Octopus Cards Ltd. had previously indicated that Apple Pay support rollout would be completed by the end of 2019. But now, it looks like Hong Kong transit riders will not be able to use their Octopus card with Apple Pay this year:
Apple Pay support will allow the Octopus card to be added to the Wallet app for contactless fare payment using an iPhone or Apple Watch. Express Transit mode will likely be supported, allowing for tap-and-go payment without needing to authenticate the iPhone or Apple Watch with Face ID, Touch ID, or a passcode.
