Paying in Hong Kong: Octopus, cards, Alipay and cash

1Octopus: the card that runs the city

Octopus is a stored-value card used on the MTR, buses, trams, ferries, minibuses, in convenience stores, supermarkets, fast food chains and a lot of car parks and vending machines. It is the single most useful thing to acquire on arrival.

• Where to get one: any MTR customer service centre, or the airport arrival hall.
• What it costs: a refundable deposit plus stored value. The card is not a credit product; you top it up.
• How to top up: cash or card at station machines, convenience stores, or through the Octopus app.
• On your phone: Octopus can be added to Apple Wallet and to Android phones, which removes the need for a physical card entirely.

For a short visit there is also a tourist version sold at the airport, but a standard card plus a top-up does the same job.

2Contactless bank cards

Visa and Mastercard contactless cards work at MTR gates, on buses and trams, in most shops and restaurants, and in a growing number of taxis. At the MTR gate you are charged the adult Octopus fare, so there is no penalty for using a card instead of a card-shaped transit token.

This means a visitor with a contactless card and no Octopus can still get around the whole city. The only gap is small merchants and minibuses that are cash-only.

3Mainland wallets: what works where

Alipay and WeChat Pay are widely accepted in Hong Kong, but "widely" is not "everywhere", and the two ecosystems are not identical to their mainland versions:

• Alipay (mainland app) works at many Hong Kong merchants that display the Alipay QR code, including chains, attractions, some restaurants and many taxi drivers.
• AlipayHK is the local wallet. It is a separate app with separate balance and promotions.
• WeChat Pay similarly works where the merchant accepts it; acceptance is thinner than card or Octopus outside tourist areas.

The practical implication: do not plan a day around paying by phone. Have a card or Octopus as the fallback, because a small noodle shop with a handwritten menu probably takes neither.

4Where cash is still needed

• Small independent restaurants, especially older ones with no card terminal.
• Wet markets and street stalls, though many now take Octopus.
• Red minibuses, which are largely cash.
• Some taxis — a growing number accept Octopus or QR payment, but not all.

Keeping HK$300–500 in small notes covers a week of edge cases without carrying a dangerous amount.

5A five-minute setup that saves a week of friction

1. Get an Octopus at the airport or your first MTR station, and load HK$300–500.
2. Add a contactless Visa or Mastercard to your phone wallet before you travel.
3. Keep HK$300 in cash, in notes of HK$100 and smaller.
4. Set your card to be charged in HKD, never in your home currency.
