Octopus Card Guide 2026: The One Thing Every Hong Kong Visitor Should Buy

The Octopus card is a rechargeable, contactless smart card that covers almost every small payment a visitor makes in Hong Kong: the MTR subway, buses, trams, the Star Ferry, and a long list of convenience stores, fast-food chains and vending machines. You tap it on a reader rather than queuing at a ticket machine for every single MTR journey, which on a multi-day trip adds up to real time saved, not just convenience.

It is not strictly required — single-journey MTR tickets exist, and some visitors get by on cash for everything — but given how often you'll be tapping through a turnstile or boarding a tram, almost every repeat visitor ends up recommending it to first-timers specifically because the alternative (counting exact change or queuing at ticket machines repeatedly) is a worse use of trip time.

There are effectively three options. The Tourist Octopus Card costs HK$39 with no refundable deposit — the fee is a flat cost, not money you get back, but it's the simplest option if you don't want to deal with a refund process at the end of your trip. The Standard Adult Octopus Card costs HK$150, split into HK$100 of usable stored value and a HK$50 refundable deposit you get back (minus a small service charge if returned within three months) when you hand the card back at an MTR customer service counter before leaving.

If you have a compatible iPhone, Digital Octopus is the best option of the three: it's free, has no deposit, sets up inside the Apple Wallet app in under two minutes, and tops up instantly with a linked card rather than requiring a physical top-up. Android support has historically lagged behind iPhone for Octopus's digital version, so check current compatibility if you're on Android before counting on it.

At Hong Kong International Airport, Octopus cards are sold at MTR Customer Service Centres in the arrivals hall and near the Airport Express platforms, as well as 24-hour vending machines. Once in the city, 7-Eleven and other convenience store chains sell the tourist version and handle top-ups, as do MTR station customer service counters and add-value machines inside most stations.

To use it, simply place the card flat on the reader at a turnstile, bus farebox or shop counter and hold it there until you hear the confirmation beep — the display usually shows your remaining balance after each tap, which is worth glancing at so you're not caught short mid-trip with an empty card at a turnstile.
