Detailed Answer Regarding Whether Taxis in Hong Kong Accept Credit Cards:

1. Mainstream Payment Method: Cash Dominates
   Taxis in Hong Kong (commonly called "taxis") generally accept cash (Hong Kong dollars) as payment, which is the most traditional and widely covered method. Drivers usually do not set a limit on change, but passengers are advised to prepare small denomination bills (such as HKD 20, 50, or 100) to avoid inconvenience with large denominations.

2. Credit Card Payment Situation

3. Some Vehicles Support Credit Cards: A few taxis (especially those with signs indicating "credit card accepted") may support credit card payments, but these vehicles make up a smaller proportion and are mainly concentrated in high-end taxi services at airports, hotels, or popular tourist areas.

4. Additional Handling Fee: If using a credit card, drivers may charge a 3%-5% handling fee (specific details depend on the vehicle's signage), which should be confirmed in advance.

5. Electronic Payment Options

6. Octopus Card (八达通): Some taxis accept Octopus Card payments (contactless), though coverage is limited, so it’s advisable to ask the driver before boarding.
7. Mobile Payments: A few drivers may support Hong Kong's local versions of Alipay (AlipayHK) or WeChat Pay (WeChat Pay HK), but this needs to be confirmed in advance if foreign accounts are bound.

8. Ride-hailing Apps with Credit Card Binding: If booking a taxi through apps like Uber or HK Taxi, you can directly bind your credit card for payment (no need for on-site settlement with the driver).

9. Practical Suggestions

10. Prioritize Cash: It is recommended to always carry sufficient Hong Kong dollar cash (especially small denominations) to deal with situations where electronic payments are unavailable.
11. Confirm Payment Method Beforehand: Upon getting into the taxi, you can proactively ask the driver: “Can I pay by credit card/Octopus/Alipay?” (in English: “Do you accept credit card/Octopus/Alipay?”).

12. Backup Plan: Exchange points are typically available at major transportation hubs such as airports, high-speed railway stations, and large shopping malls, allowing you to exchange currency anytime; convenience stores in Hong Kong (such as 7-11) also offer foreign currency exchange services.

13. Additional Fee Reminder
    Hong Kong taxis may charge extra fees, including:

14. Baggage fee (HKD 6 per piece for luggage placed in the trunk)
15. Tunnel fee (if passing through the sea tunnel, round-trip fees apply)
16. Nighttime/holiday surcharges (specific amounts are displayed on the meter)
    These additional fees must be paid in cash and cannot be settled via credit card.
