I've just youtubed contactless payment cards and it says that you have to enter your pin number the first time you use it, and may be asked at random times to enter you pin number again. Last time I tried to take a bus I was thrown off for having the temerity to try to pay with money, hence my anxiety about how to pay on the tube. Are the contactless card machines already in place in Turnham Green Station, and do you have to touch as you go in and again as you go out, with the fare being calculated automatically? |
