FAQ

No. Citi Octopus Card on iPhone or Apple Watch does not have credit card function, hence it can only be used with Octopus readers.

This transaction is incomplete. Please follow the merchant's instruction, tap the Octopus on the reader again to hear a "dood" sound for a complete transaction and see the remaining value. This will NOT cause a double deduction.

No. Just hold your iPhone and Apple Watch above any Octopus reader to make payments for transport, retail outlets and access control without using Face ID, Touch ID or passcode. There is no need to wake or unlock the device or open any apps.

If you have previously added other transit card to Apple Wallet before, you may need to enable Express Transit mode for Octopus manually by: Open Wallet > select Octopus > click "…" > click "Express Travel Settings" > select Octopus*

* The first Octopus that you add to Wallet automatically becomes your Express Transit card. You can change your Express Transit card in Wallet at any time. You may need to open Apple Wallet and select Octopus to pay on mobile phones functioning as an Octopus card reader.

It may be due to the ‘Express Travel’ function being temporarily locked, a safety feature provided when there are several unsuccessful attempts in biometric authentication on your iPhone (such as Face ID unable to recognise you with a face mask on, or unintentional engagement of Touch ID or pressing of buttons) . Simply unlock your iPhone, and tap the reader again to make the payment.

Citi Octopus Card on iPhone or Apple Watch does not require an Internet connection when paying for transport and retail purchases as Apple Pay utilizes NFC technology for transactions.

The exceptions are functions that require an Internet connection, e.g. adding a new Citi Octopus Card on iPhone or Apple Watch, or initiating money transfers from Octopus Wallet.

On iPhone XS, iPhone XS Max, iPhone XR and later models, you can use power reserve with your Express Transit cards. Power reserve enables you to quickly pay for rides and depending on your device, it's available for up to five hours when your iPhone needs to be charged.

If the remaining value of your Citi Octopus on iPhone or Apple Watch is positive (HK$0.1 or more) but insufficient to cover the payment of a particular transaction, the Octopus can still be used provided the resulting negative value does not exceed the auto-reload amount of built-in Automatic Add Value Service (AAVS).

There are a number of possible causes for this problem:

• Ensure you hold the top of the iPhone up to the middle of the Octopus reader
• Please hold the iPhone or Apple Watch over the reader until you hear the "dood" sound
• Remove any materials that may interfere with the transaction, such as metal cases or other Octopus or plastic contactless payment cards
