Can two people share one metro card?

Depends on the city. New York allows card sharing for pay-per-ride but not unlimited passes. London requires one card per person always. Paris allows sharing on some ticket types. Check your specific city's rules. When in doubt, get one card per person to avoid gate rejections and delays.

What happens if I lose my metro card?

Unregistered cards are gone forever with no refund. Registered cards (London Oyster, Hong Kong Octopus, Japan IC cards) can be frozen and reissued, but you need the card number or registration details. Take a photo of both sides of your card when you first get it. This helps with reporting and replacement.

Do metro cards work in suburbs and airport trains?

Usually yes, but sometimes at higher fares. London's Oyster works to Heathrow but costs more than central zones. Paris Navigo works to CDG airport. Tokyo IC cards work on almost every train in Japan. Check zone maps when buying if you plan airport or suburb trips. Some cities sell special airport express tickets separately.

Can I buy metro cards online before I travel?

Some cities allow it, most do not. London lets you order an Oyster card shipped internationally. Japan lets you buy virtual IC cards on iPhone. But most cities require in-person purchase. Do not stress about pre-buying. Airport and station machines are straightforward, have English options, and buying on arrival takes 5 minutes.

Are tourist passes better than regular metro cards?

Rarely. Tourist passes often bundle museum entry or hop-on buses you will not use, inflating the price. A regular unlimited metro card is usually cheaper and more flexible. Run the numbers. If you want the included attractions, tourist passes can work. For transit only, stick with the standard metro card locals use.

Getting and Using Metro Cards When You Travel

Metro cards are reloadable transit passes that save time and money in most major cities. Buy them at ticket machines or transit stations on arrival, load enough credit for your stay, and tap or swipe at gates. Most cards work across all transit modes in the city and cost 5-15 dollars for the card itself plus whatever you load onto it.

Buy the card at the airport or major station. Look for ticket vending machines or transit service centers when you arrive. Airport stations almost always have English language options on the machines. You will pay a one-time card fee (usually 2-10 dollars) plus whatever initial balance you want to load. Start with 20-30 dollars and reload later if needed.
Choose between pay-per-ride and unlimited passes. If you are taking more than 2-3 trips per day for several days, an unlimited pass usually saves money. For occasional use, pay-per-ride is better. Do the math: multiply the single-ride fare by how many trips you plan to take, then compare to the unlimited pass price. In New York, for example, break-even is around 12 trips on a 7-day pass.
Load enough value to avoid constant reloading. Running out of credit mid-trip is frustrating. Load at least 2 days worth of expected trips at once. You can reload at any station ticket machine, but it takes time. Most cards hold a maximum balance of 100-200 dollars, and unused credit is refundable or good indefinitely in most cities.
Learn your city's tap or swipe system. Some cities require a tap on entry and exit (London, Singapore). Others only need a tap on entry (Paris, Tokyo). A few still swipe (New York). Watch other passengers or ask station staff. Tapping out when required prevents overcharges. Not tapping out when required can lock your card or charge maximum fare.
Keep the card in the same place every time. Always store your card in the same pocket or wallet slot. Fumbling at turnstiles during rush hour while locals pile up behind you is avoidable stress. Some cards work through thin wallets or phone cases. Test this once at a quiet station before relying on it.
Check if the card covers buses, trams, and trains. Most modern metro cards work on all transit modes in the city. Confirm this when buying. In some cities like Rome, you validate the card differently on buses versus trains. In others like Seoul or Hong Kong, the same card tap works everywhere including convenience store purchases.
Get a refund or keep it for next time before leaving. Many cities refund unused balance and card deposit at ticket offices. Others let you keep the card active for years. If you plan to return, keeping the card saves the reissue fee next time. Check refund policies before your last day. Some cities charge a small processing fee for refunds under 10 dollars.
