There are certain bank cards, that work as travel-cards, but I doubt anyone coming from abroad would have one of those. However, anyone can buy an Oyster card from a ticket vending machine at most train and tube station, then top it up (at the same machine, or online) and use that credit to pay for almost all public transport in London. Once the cost of your journeys in a day reaches the cost of a daily travel-card for the zones you've been traveling within - the rest of your travel that day - within those is free.
You can also use the Oyster card as a weekly travel-card.
Sweet, thanks - so it does the math for you to get you the best deal. Nothing is worse than accidentally wasting money on an inefficient ticket - the other day I accidentally payed $2.20 at an automated machine to travel zero stops at a train station. I felt like a complete idiot
It only does this on a daily basis though. If you are going to be there multiple days you need to figure out which is more cost effective. http://www.londontravelpass.com/prices.html
If you use an Oyster card, you won't be charged more than £6.40 a day (for zones 1-2). A weekly travelcard for zones 1-2 is £32.10.
32.10 / 6.40 = 5.01
So if you are only going to be there for 5 days, you don't need a weekly travelcard. If you will be there for 6+ days, a weekly travelcard is more cost effective.
Also take into consideration that you have to add money to your Oyster card if you don't have a travelcard loaded on it, so it might be worth the hassle to buy one anyway.
