Does the Hong Kong MTR accept international credit cards for ticketing? If you’re visiting Hong Kong and wondering whether you can use your foreign credit card to buy metro tickets, the answer is yes, but with some limitations. Most MTR stationing machines accept major international credit cards like Visa, Mastercard, and American Express. However, not all machines are guaranteed to process cards smoothly, and some may prioritize Octopus card readers or cash payments. To avoid hassle, carry a few hundred Hong Kong dollars (HKD) as a backup, especially if you’re traveling during peak hours or to smaller stations. Alternatively, consider purchasing an Octopus card—Hong Kong’s versatile transit card—which can be topped up with cash or credit cards at select locations.
