Short answer
Yes, get one. The Octopus is Hong Kong's stored-value smart card, and it is accepted at around 190,000 points across the city — the MTR, buses, green minibuses, trams, ferries, the Airport Express, 7-Eleven, supermarkets, fast-food chains and vending machines. You tap it and walk on. It works offline, needs no bank account and no phone.
For a short trip the On-Loan Octopus is the right default: HK$150 in total, which is a HK$50 refundable deposit plus HK$100 of stored value. Buy it at any MTR Customer Service Centre or at the airport on arrival. With an iPhone X or newer, or an Apple Watch Series 3 or newer, you can skip the card entirely and add a Mobile Octopus through the free Octopus App for Tourists.
Two things to know before you leave. First, Octopus is not a substitute for cash — market stalls, some taxis and small shops still want notes. Second, the On-Loan card is refundable: return it to any MTR Customer Service Centre for the deposit and remaining balance, minus a handling fee if you return it soon after issue.
What the Octopus actually is
It is a contactless stored-value card that has been running since 1997, well before contactless bank cards were normal. Money sits on the card, not in an account, so it works with no network connection and no registration: you tap it on a reader, hear a beep, and the remaining balance appears on the screen.
Its real value for visitors is that Hong Kong's transport is not one system. The MTR, buses, minibuses, trams and ferries are run by different operators, and Octopus is the one payment method that works on all of them — slightly cheaper than buying a single-journey ticket on the MTR.
Which one to buy
| Type | Cost | Best for |
|---|---|---|
| On-Loan Octopus (adult) | HK$150 = HK$50 refundable deposit + HK$100 stored value | Almost every visitor. Refundable when you leave. |
| Tourist Octopus (Sold version) | Around HK$39 for the card, no deposit; you add value on top | You want the card as a souvenir and do not care about the deposit. The card price is not refundable. |
| Mobile Octopus (iPhone / Apple Watch) | No deposit; you load value in the app | You have an iPhone X or newer and would rather not carry a card. |
| Child / Elder Octopus | Lower deposit-plus-value package | Children aged 3–11 and seniors 65+ get concession fares. |
There is also an Airport Express Travel Pass, bundling one or two Airport Express journeys with a period of unlimited MTR travel. It only pays off if you are definitely taking the Airport Express and riding the MTR heavily — for most people a plain On-Loan Octopus plus a separate Airport Express fare is simpler. These packages are repriced periodically, so check Octopus's own site.
Where to get one
- MTR Customer Service Centres, at every station, including the airport. The most reliable option.
- Hong Kong International Airport, MTR counters and convenience stores in the arrivals hall. Expect a queue right after a big flight lands.
- 7-Eleven and Circle K, sell the Tourist (Sold) version, sometimes with limited-edition designs.
- Before you fly, with an iPhone or Apple Watch, the Octopus App for Tourists sets up a Mobile Octopus in minutes and removes the airport queue entirely.
You do not need ID to buy an ordinary On-Loan Octopus. Personalised cards, registered to a name and blockable if lost, are aimed at residents rather than visitors.
Topping up
Top-ups take seconds and are everywhere: Add Value Machines in every MTR station take cash notes, and convenience stores and supermarkets will add value at the till. Mobile Octopus users top up inside the app.
The maximum stored value is HK$3,000. For a short visit, HK$200–300 at a time is plenty, treat the card like cash, because a lost anonymous card means a lost balance.
What it covers, and what it does not
| Works with Octopus | Does not work with Octopus |
|---|---|
| MTR and Light Rail | Most market stalls and street food vendors |
| Public buses and green minibuses | Many taxis — carry cash as a fallback |
| Trams (the "ding ding") | Some small independent restaurants |
| Star Ferry and most ferries | Anything priced in another currency |
| Airport Express | Red minibuses, which usually want exact cash |
| 7-Eleven, Circle K, supermarkets, fast food, vending machines |
Mobile Octopus: worth it if you have an iPhone
You download Octopus App for Tourists, add an Octopus to Apple Wallet, and from then on you tap your iPhone or Apple Watch on exactly the same readers as a physical card, no need to open an app or unlock the device.
- Hardware: iPhone X or later, or Apple Watch Series 3 or later.
- Top-up funding: a non-Hong Kong issued Visa, Mastercard or UnionPay card in Apple Pay, or via Weixin Pay or e-CNY.
- No deposit, and refunds are handled inside the app and credited back to the card you paid with.
- Trade-off: it is tied to one Apple ID and one device, so you cannot hand it to a travel companion, and a flat battery means you cannot tap.
Android visitors have fewer options. Octopus on Android officially supports only specific Samsung and Huawei models sold in Hong Kong, so most overseas Android users should plan on a physical card.
Getting your money back
Take a physical On-Loan Octopus to any MTR Customer Service Centre on your way out. You get the HK$50 deposit and the remaining balance back in cash on the spot. A handling fee applies if you return the card soon after issue, the current figure is published on Octopus's site.
Two exceptions to know:
- The Tourist (Sold) version is not refundable. You paid for the card itself and that money is gone. You can still cash out any remaining stored value at an MTR counter.
- Mobile Octopus refunds are applied for in the app and credited back to your original payment card, usually within a few working days. A handling fee applies if you refund within 90 days of issue.
What about cards and cash?
Hong Kong is not cashless in the way mainland China is. Contactless Visa and Mastercard work at many shops, hotels and restaurants. But the layer visitors actually enjoy, the market stall, the noodle shop, the dai pai dong, is still frequently cash-only, and the taxi you flag at 1am may want notes.
The practical setup: Octopus for transport and convenience stores, a contactless card for restaurants and shops, and a few hundred Hong Kong dollars in small notes for everything else.
Frequently asked questions
Do I really need an Octopus card in Hong Kong?
For anything longer than a day, yes. It is the only payment method that works across the MTR, buses, minibuses, trams and ferries, it is slightly cheaper than MTR single tickets, and it removes the need to find exact change. It works in convenience stores too.
How much does an Octopus card cost?
An adult On-Loan Octopus is HK$150, which breaks down as a HK$50 refundable deposit plus HK$100 of stored value. The Tourist (Sold) version is around HK$39 for the card with no deposit and no stored value, you add money separately, and the card price is not refundable.
Can I use my credit card instead of Octopus?
Contactless Visa and Mastercard are accepted at many shops, restaurants and hotels, and the Airport Express takes them directly. But buses, minibuses and trams generally do not, so you still need Octopus or cash for local transport.
Can I get an Octopus on my phone?
Yes, with an iPhone X or later or an Apple Watch Series 3 or later. Download the Octopus App for Tourists, add an Octopus to Apple Wallet, and top it up with a non-Hong Kong Visa, Mastercard or UnionPay. Android support is limited to specific Samsung and Huawei models sold in Hong Kong.
Where can I top up an Octopus card?
At Add Value Machines in every MTR station (cash) and at the till in 7-Eleven, Circle K and most supermarkets. Mobile Octopus users top up inside the app. The maximum stored value is HK$3,000.
Do I get my deposit back when I leave Hong Kong?
Yes, for the On-Loan version. Return it to any MTR Customer Service Centre and you get the HK$50 deposit plus any remaining value in cash. A handling fee applies if you return it soon after issue. The Tourist (Sold) card is not refundable.
Can I share one Octopus card with my travel companion?
No. An Octopus cannot be used twice within a short time window, so two people cannot tap the same card through a gate. Each traveller needs their own card, including children, who can use a Child Octopus for concession fares.
Does Octopus work outside Hong Kong?
Some versions do. The Tourist Octopus, China T-Union variant works on participating public transport in mainland China and Macao, though conversion fees can apply. A standard On-Loan Octopus is a Hong Kong product.
