Lea: Hi, I need to travel on the Tube, but I don’t have an Oyster card. Is that possible?

John: Yes, of course, you can still buy paper tickets. But there are Visitor Oyster cards, too, you know.

Lea: Oh, really? I didn’t know that. Isn’t that a lot more expensive, though?

John: No, fares are actually cheaper than single paper tickets or paper Travelcards.

Lea: But don’t I need to pay for the card itself

John: Yes, it’s a contactless card that costs £5. You load it with credit which you pay as you go.

Lea: I’m only here for the weekend. What happens if I haven’t spent it all?

John: Whatever credit you have left never expires. Then, if you come back, you just top it up.

Lea: Oh, well, I’m sure I’ll be back, so I guess that’ll be useful. OK, one Oyster card please, with £15 credit!

John: Here you go. Make sure you touch your card to the reader at the start and the end of your journey, so you’ll be charged the right fare.

Lea: Will do. Thank you!
