Most Cost-Effective Way to Top Up Tourist Octopus in Hong Kong (2026)
Use the Octopus App for Tourists on iPhone X or later, or top up with cash at MTR service centers. Both are fee-free. The app accepts non-Hong Kong issued Mastercard, UnionPay, or Visa via Apple Pay; it also takes a non-Hong Kong Mastercard linked directly inside the app, plus WeChat Pay and the e-CNY app. Octopus charges no top-up fee on any of these methods, but your bank sets the exchange rate when the card is reloaded. To avoid Dynamic Currency Conversion (DCC) at the till, always select HKD when given the choice. Withdraw HKD from an ATM with a fee-free debit card (Wise, Revolut, Charles Schwab) and top up the physical Octopus at any 7-Eleven or Circle K register; minimum top-up is HK$50. The standard Adult Octopus costs HK$150 with a HK$50 refundable deposit. Refund the card at MTR customer service centers before flying out: HK$11 fee applies if you return it within 3 months of issue, otherwise refund is free. Apple Pay's tourist Octopus skips the deposit entirely and refunds the unused balance back to the linked card, which is the cheapest setup if you have a compatible iPhone.

How this works
Download the Octopus App for Tourists
Get the app from the App Store on your home country account. Confirm your iPhone is iPhone X or later, or Apple Watch Series 3 or later. Open the app and follow the setup; no Hong Kong phone number needed.
Add a foreign Mastercard or Visa via Apple Pay
Tap Add Card in the app. Pick Apple Pay and select a non-HK Mastercard, Visa, or UnionPay. Confirm the card with your bank's authentication. The app links the card to your tourist Octopus account in under 2 minutes.
Top up with the minimum HK$50
Tap Top Up and choose HK$50 or higher. Confirm via Face ID. The balance is available immediately for use at MTR gates, buses, and 7-Eleven. Octopus charges no fee; the bank's own exchange rate applies.
Always pick HKD at the card terminal
When a merchant offers Pay in your home currency or HKD, pick HKD. The home-currency option (DCC) adds 3 to 5 percent on top of your bank's rate. This applies to ATM withdrawals and card top-ups at MTR machines.
Refund unused balance before flying
For Apple Pay Octopus, open the app and tap Remove Card; balance refunds to your linked card in 3 business days. For physical cards, hand the card and your passport to any MTR customer service center; refund is on the spot.
Why this is different for foreign visitors
Unlike most cities where one transit card is the default, Hong Kong runs Octopus as the universal payment for transit, vending machines, convenience stores, and many small restaurants. The card predates contactless bank cards by 20 years, and locals still prefer it for sub-HK$500 payments. For foreign visitors this means a tourist Octopus is more useful than a contactless Visa, even in 2026 when most foreign cards work on the MTR via direct contactless. The trade-off is the deposit and the refund hassle on departure. Apple Pay's tourist Octopus removes both and is the path of least resistance for iPhone users.
Common mistakes to avoid
- Picking your home currency at the MTR top-up machine. DCC adds 3-5 percent to every reload; always choose HKD.
- Buying a physical Octopus when you have a compatible iPhone. The Apple Pay tourist Octopus skips the HK$50 deposit and the refund queue.
- Returning a physical Octopus within 3 months and complaining about the HK$11 fee. The fee waives after 3 months; plan accordingly or expect the deduction.
Frequently asked
